Despite Help From Microsoft, SQL Injections Remain A Threat

Any SQL-based database server is vulnerable to a SQL injection, but the ones that have wreaked havoc this year have been directed at Microsoft's SQL Server via malicious code in a SQL query string, directed to the database via a Web app.

As reported last week, the number of unpatched Web sites that are exposing malicious code still is alarmingly high -- some seven of 10 Web apps are unsafe, according to Cenzic's Intelligent Analysis Lab report.

Of particular concern to database developers is the fact that one in five of those measured for by Cenzic had SQL injection applications. The finding comes as Microsoft released a new security filter for its Internet Information Services (IIS) Web server aimed at thwarting such attacks.

Microsoft's UrlScan 3.0 is an upgraded version of a five-year-old tool that now examines the query string in a SQL query request. That allows developers to create more granular rules for specific types of requests, Wade Hilmo, senior development lead on Microsoft's IIS team, which wrote UrlScan, told Redmond Media Group online editor Kurt Mackie. "For example, you can write a rule that only applies to ASP pages or PHP pages," Hilmo says.

While a step in the right direction, Kevin Beaver, founder and principal information security consultant of Atlanta-based Principle Logic LLC, tells Mackie that the features in UrlScan are rather basic. "It's good the features are now available, but getting admins and developers to actually upgrade is a whole different issue," Beaver tells Mackie.

And therein lies the problem. Until patching systems becomes a priority at the CIO levels, hackers are going to continue to have a field day.

Is your organization taking these threats more seriously? Drop me a line.

Microsoft Unleashes SDK For SSDS

The first beta of SSDS was released back in March, announced with much fanfare at the Mix08 Conference by Microsoft chief software architect Ray Ozzie

The SDK includes the command-line tool and the SSDS Explorer demonstrated by Soumitra Sengupta at TechEd back in Orlando in June. "The team would appreciate if you can give it a spin and let us know what you like, what you do not like and above all file bugs that you see," Sengupta wrote in an MSDN posting yesterday. Testers do need an SSDS account in order to use the SDK, he noted. The SDK can be downloaded here.

Sengupta also suggests Microsoft may open up the SSDS tools. "I am personally curious to find out if there is any interest in the community to take over the code base for these tools," he asked in a follow-up post late yesterday.

If you haven't paid much attention to SSDS, perhaps you should -- it appears to be a key component of Microsoft's plan to offer a cloud-based repository for data-driven content. Microsoft, Google and others are looking to the success Amazon.com is having with its S3 cloud-based repository and the companies have come to the conclusion that this is the future of enterprise computing.

Have you looked at SSDS and the new SDK? Please share your stories with us.

Java Developer Idolizes .NET

It's worth noting that Arora, a native of Bombay, India and currently attending Georgia Tech, is a Java developer who came to New York this summer with no prior .NET programming experience.

The clincher though, was that his project outshined presentations of five other seasoned developers who all outlined their own respective programming case studies at an "American Idol"-themed bakeoff called "Speaker Idol," held by the New York City .NET User Group last month.

During Arora's 10-minute presentation to a room full of local developers, held at Microsoft's midtown offices, Arora, who was the last of the six presenters, described his project. When he began his summer internship at Morgan Stanley's Investment Management group, the firm's asset management unit, he took on the task of providing better interoperability between the trade-order generation tools used by portfolio managers developed in Visual Basic for Applications with Microsoft Office as a front end and disparate Java-based back-end systems.

Arora said replacing Office with a Java-based UI was not an option. "Office in the enterprise is ubiquitous, it's familiar, it's powerful and extensible -- why take it away from my users and try to make a Java UI?" Arora explained.

As a result, he spent six weeks building reusable services oriented applications using Visual Studio Tools for Office. The SOA-based components provide connectivity between Office Business Applications and Java-based backend infrastructures such as IBM's DB2 and Sybase databases. Those repositories are typically non-Windows-based, running on Linux and Apache servers.

VSTO's rapid application development environment allowed him to create .NET services that could be consumed by different Java-based systems, Arora said. The goal was to improve the business process of how trade orders are generated. "It provides access to business process services in a standards-based approach," he said of the way processes are defined in VSTO.

"The code is not just written in VBA [where just] one portfolio manager is going to use it," he said. "[Now] everybody is going to use it; it will run on a Java back-end."

To build the order generator, Arora used VSTO 2003 using C# and WinForms. On the back-end he used Sun Microsystems Java EE -- Apache CXF, JAXB, Hibernate, Spring, and Apache Tomcat, among other tools.

In an interview following his presentation, Arora told me the biggest challenge was that he had never used .NET or Visual Studio before. "I'm a Java developer at heart," Arora said, though he said he did not encounter any difficulty figuring out .NET and VSTO. "It's a different world, but it's been very nice."

Does that make Arora a .NET convert? "I can think of some use cases where I might expand on my .NET experience," he said.

Arora was the only student in the competition. The six developers showed a variety of programming efforts ranging from the use of F# to arithmetic algorithms, before a panel of four judges: Andrew Brust, chief of new technology at twentysix New York; blogger Mary Jo Foley; Peter Laudati, a developer evangelist and Kathleen McGivney, a software consultant. Stephen Forte, chief strategy officer at Telerik, organized and moderated the event.

"We thought his presentation was the most broad-based, well rounded and he did the best job of conveying a business case, and really explaining it clearly," Brust said of the panel's decision to name Arora the winner. The prize: an Xbox 360.

SQL Server 2008: It's Here

Officials from Microsoft's Data Platform Group held a conference call for analysts and press to announce the RTM. The company had indicated last month that its release was imminent despite skepticism to the contrary.

Among the key new features Microsoft is touting is support for policy management, improved use of data encryption, the ability to store and query spatial data, a new report builder and improved support for analysis, reporting and administration. It also boasts new data compression capability, which the company said makes better use of storage and provides faster queries.

Microsoft officials belabored the point that organizations can upgrade without having to modify their software. "Customers can adopt these enhancements and features without making changes to their applications," said Ted Kummert, corporate vice president of Microsoft's Data and Storage Platform division.

But that raised another question on the call: Will Microsoft's cloud-based incarnation of its forthcoming database platform, dubbed SQL Server Data Services, or SSDS, be just as seamless to developers or will they require new interfaces or development methodologies?

"As we move things forward, I think you will see things change," Kummert said. "Our focus today is on SQL server 2008. I think in the next year, you will see a lot of clarity emerge around SSDS and how SSDS relates to our overall data platform. But the overall commitment is clear, that we are spanning this data platform vision to the cloud and we will provide a consistent application model across all tiers -- that is the edge, the data center and the cloud."

With so much buzz about cloud computing, this will certainly be something to watch.

Database Growth Points To Open Source

Both IT research firms last month released their annual market share reports for database software. SQL Server revenues grew 16.5 percent in 2007 over the prior year, compared to Oracle, which grew a more modest 14.9 percent, and IBM, which was up just 10 percent, according to Gartner analyst Donald Feinstein. However Oracle and IBM's revenues come from a much higher base -- $48.6 billion and $20.7 billion respectively, compared with SQL Server's $18.1 billion.

Microsoft's license fees tend to be lower than its larger rivals, suggesting unit-wise even more substantial growth for SQL Server. But the latter database server platform only runs on Windows, hence limiting its proliferation within the enterprise.

In the Windows server market, SQL Server accounts for a dominant share of 51.4 percent, compared with 28.8 percent for Oracle and 9.8 percent for IBM. In the Windows market, Oracle's growth of 21 percent outpaced Microsoft's 16.5 percent.

All that noted, Gartner this year drilled deeper into the open source database market.

The steady growth of open source database software could affect license fees going forward, Feinstein predicts. Until this year, Gartner had only broken out open source databases as a whole -- accounting for about 1 percent of the market. Having broken out the key players, here is the rundown: MySQL revenues were $65 million, up 46.9 percent, Ingress was just shy of $40 million, up 100 percent, and EnterpriseDB, supplier of the popular Postgres database was up nearly 9 million, though revenues were up 282 percent.

Feinstein points out since the open source database licenses are free, it's hard to compare it to suppliers of licensed software. Revenues for open source database software, of course, are all for services, etc. Because open source database software lags the features of licensed software today, it has not been a threat, but Feinstein says that could change over time.

"Looking out five years, if open source databases can start to be used in mission critical situations, they could have a major impact on pricing," he said.

Changing of The Guard on Microsoft's SQL Server Team

For Ibarra's part, it's onward and upward to the next release of SQL Server, where, if history should be our guide, will come out somewhere around 2011 -- though to be clear, that's what observers suspect. That didn't come from Ibarra or anyone else at Microsoft. All he would offer up on that front is Microsoft's goal of making it easier to manage all content across multiple tiers ranging from mobile devices to the cloud.

Key to that, he offered, will be Project "Velocity" and SQL Server Data Services. You can read more about Ibarra's plans in his new role here.

Data quality apparently is another key area of focus for SQL Server. The company's announcement this week that it will acquire Israel-based Zoomix gives it entrée into that space. The little-known startup offers what it calls Data Accelerator, server-based software that it says provides a scalable and fast approach to synchronization of critical data.

Data quality is an important aspect for numerous business operations, among them identity management, but it remains to be seen how much of a focus Redmond and its other key rivals will place on this area.

"If any of their customers have a need for a powerful matching engine, Zoomix has a pretty interesting product," says Forrester Research analyst Rob Karel. "It's relatively new; they have some customers but for the most part it's really an early stage technology that Microsoft acquired."

It remains to be seen whether Microsoft's key goal was to acquire the product or the team and presence in Israel, adds Gartner analyst Donald Feinstein. "Instead of buying a major vendor of data quality, they bought a development team in Israel," Feinstein says. "It will pay off in that they get the product that they got to date, but they also get the developers out of it."

SQL Server To Ship This Quarter: Should It?

Also raising doubts were testers of SQL Server 2008, saying there were still numerous bugs in the CTP. But Redmond officials insisted that SQL Server 2008 was still on track to be released to manufacturing in the third quarter and urged testers to report any bugs.

Now it appears it won't slip. At yesterday at Microsoft's Worldwide Partner Conference in Houston, the company said the database is on pace to be released by September 30th.

Fausto Ibarra, Microsoft's new director of product management for SQL Server, told me that he is quite confident that SQL Server 2008 will be ready to ship.

"The release candidate we have is feature complete, so our customers and partners can try out absolutely everything SQL Server offers," Ibarra says.

Still, among those who had raised doubts back in May was Andrew Brust, chief of new technology at twentysix New York, speaking at a meeting of the NYC .NET User Group, a user group he not so coincidently founded. I asked Brust for his reaction of Microsoft's latest announcement.

"There is mounting evidence that a Q3 RTM is the reality," Brust said in an e-mail, though he remains skeptical. "I'm still dubious, but that might be irrational at this point. I would, in any case, greatly prefer to see one more RC before RTM. That would raise my comfort level enormously."

It's not clear, however, whether Brust will see his comfort level rise. While Microsoft's Ibarra hasn't ruled out another release candidate, he sounded quite comfortable with the stability with the current build.

"We are getting some reports of bugs," he admits. "It's usual -- it's actually a small number. By now the product is very solid. We already have a lot of customers in production, we have a lot of applications that Microsoft is running on SQL Server 2008, including SAP -- we all get paid because of SQL Server 2008. At this point we are just in the final stages of testing."

Ibarra says a decision whether to issue another release candidate will come within a few weeks. What's your take? Is SQL Server 2008 almost good to go? Drop me a line.

ADO.NET Entity Framework Saga

Ironically, I got wind of the protest on Tuesday while attending the Data Services World conference in New York, where none other than Michael Pizzo, a principal architect on Microsoft's data programmability team, was giving a session on LINQ, the Entity Framework and ADO.NET Data Services.

In his session, he demonstrated LINQ queries being used against the Entity Framework. "We expect [that] when you're using the Entity Framework and writing applications against the Entity Framework, LINQ will be the primary way you do that," he explained in an interview following his demo.

As for the online petition, Pizzo was unaware of it until I pointed it out to him (it was posted just this week). However, he said the discord comes from what he called a "vocal subgroup." Pizzo said the issues raised are under consideration for a future release.

"While we certainly take them seriously and are planning on addressing many of their concerns, specifically around persistence ignorance in the next release, we have a large number of customers who see value in the Entity Framework as it is in version 1," Pizzo said.

For his part, Tim Mallalieu, a Microsoft product manager, posted a detailed response to the no-confidence vote in his blog.

Not surprisingly, the controversy has generated a lot of buzz. OakLeaf Systems Principal Consultant Roger Jennings pointed out in his own blog that this vocal group is spearheaded by NHibernate proponents.

And today, Jennings pointed to a blog post by Ian Cooper, proponent of LINQ to SQL but an opponent to Entity Framework and a Microsoft MVP, who argued that this is history repeating itself (see circa 2000 when complexities around Enterprise Java Beans surfaced).

"EJBs were an ambitious attempt to support persistence, transactions, events, RPC, etc. in a single component," Cooper wrote in his blog. "While there was an initial rush to adoption, they quickly proved a millstone around the Java communities' neck, because of their complexity. Technologies like Spring and Hibernate emerged as less complex ways of delivering enterprise-class solutions. Many of them were later to be incorporated into drastically revised EJB visions."

Cooper believes the .NET community can learn from that. "Ports of Hibernate and Spring offered the community the chance to avoid the mistakes of the past," he added. "However, seemingly unaware of the lessons of history, the EF team embarked on a project to produce a complex framework, of which persistence is just one aspect, reminiscent of the EJB initiative."

Jennings described Cooper's assessment as a "level-headed critique of the Entity Framework v1."

So what's your take on this? Will this affect the choices you make as you embark on developing new data-driven apps using the Entity Framework and related technologies? Drop me a line at jschwartz@reddevnews.com.

With Velocity, There's Winners and Losers

Many jaws dropped when Microsoft unveiled Velocity -- not just as a project but with enough code to allow developers to test.

William Bain, CEO of ScaleOut Software, told me this week he was blindsided about Velocity, only getting wind of it days before its announcement. Particularly troubling, said Bain, is that ScaleOut is a Microsoft partner that is on the fourth release of its distributed cache server, dubbed ScaleOut StateServer (SOSS), used by a number of large organizations -- including Home Shopping Network and Reuters -- for high-performance applications.

"This was a surprise to us," Bain said. "We are a Microsoft partner focused on high-performance computing, particularly in the financial services market and we've had a positive and successful relationship with them over the past year."

Because Microsoft has hedged on its product plans, many are speculating that the software giant might offer Velocity free of charge or, at the very least, put the squeeze on other players like ScaleOut.

"The steps they take over the next year will determine whether it has an effect on the market," Bain said. "If Microsoft should elect to make distributed caching available as its own standalone SKU free of charge, that does undermine the market for products of this type, coming from vendors that have worked for years to develop and evangelize this market and that has a negative effect on investment for new Microsoft-related technologies."

ScaleOut's pain, of course, could mean customers' gain. "A free entry into this arena from a major vendor is sure to make the other vendors think about lowering their prices," wrote Marc Adler, technical head of complex event processing at a major investment bank on Wall Street, on his blog. "In these economic times, financial companies will certainly welcome the chance to embrace this technology without having to spend a lot of money."

There are still many unknowns about Velocity, Adler points out. Among his questions are what product group will commercialize it, how will it be tied to LINQ and SQL Server, will it have support for third-party (even Java-based) message busses, and will it link to non .NET environments and database servers other than SQL Server.

As for whether or not it will commoditize in-memory data caching, ScaleOut's Bain believes time is on his side. Based on the current CTP, Velocity only provides a subset of the functionality in SOSS, Bain said. For example, SOSS already supports high availability of stored data, offers a self-configuring and -healing architecture, offers quorum-based updating of stored objects, supports push notification of events within the cache, offers asynchronous replication between data centers for disaster recovery and parallel query of cached objects using tags.

If Microsoft ends up giving away Velocity or bundling it with other tools, Bain said the onus on suppliers of distributed caching technology will be to add value in other ways.

That said, he also knows if you can't beat them, join them. For example, he didn't rule out supporting Velocity and the APIs that come with it.

"I think the Velocity API may become a defacto standard as the lowest common denominator API that everybody will support," he said. "In addition I think vendors like ourselves and our competitors will add value; I know that we will add value beyond those APIs."

Microsoft's Latest Data Driver: Velocity

Velocity is designed to provide high-speed access to data developed in .NET via partitioned, replicated or local caches. "It's an application cache," said Anil Nori, a distinguished engineer in Microsoft's SQL Server group. Naturally, given his roots, I asked him if this is seen as an alternative to using the SQL Server repository. Nori explained the rational for data caching software, which he sees as a separate tier in the application stack.

"Today we have ASP.NET applications, which are going off to SQL Server," Nori said. "One of the bottlenecks we have is how do we scale our session state. The way we solve this is to use a distributed cache and you keep the session state in the cache, and it can provide a really large-scale place to really hold a session cache. Then you can provide better performance and scale."

What is not clear is Microsoft's intentions for commercializing Velocity. The company released it as a community technology preview (CTP) last week .

"We haven't figured out what is a long-term set of facilities, but one thing we feel strongly, is that it is aligned with the .NET stack rather than SQL Server," he said.

Nori did explain that CTP 1 Velocity offers dynamic scaling by adding nodes in memory and provides automatic load balancing and high availability by distributing copies of data across multiple nodes. However, it does not support any availability, Nori said.

In CTP 2, Nori believes Microsoft will offer higher functionality and it will round off with the utilities necessary to loading the caches, including high availability and improved integration for manageability. Microsoft is targeting its Professional Developers Conference in late October for that release, followed by a full release sometime in the second half of next year.

Meanwhile, Velocity caught a number of industry watchers off guard, though others say it makes sense for Microsoft to offer an in-memory data cache to help rev .NET applications.

"That wasn't something I saw coming," said Daniel Chait, managing director of New York-based Lab49, in an interview during this week's Securities Industry and Financial Markets Association (SIFMA). What remains to be seen, Chait said, is whether Microsoft plans to release Velocity as a product and in what form.

There are a number vendors who offer their own distributed cache products, among them GigaSpaces, Gemstone Systems, Oracle's Tangosol and ScaleOut Software. "[These companies] spent a lot of research and development money; they are naturally going to be upset," Chait said.

In fact, ScaleOut, took the unusual step of expressing its dismay in a press release. "We are disappointed that this surprise announcement has created confusion for our customers," the release stated.

Gideon Low, GemStone's principal architect, said during an interview at SIFMA that caching is just one component of its product family, which includes support for among other things complex event processing.

"It's really our roots. We began our product as a distributed caching product, but today it's really just a component of a much larger technology suite that we have," says Low. "Managing data in memory is very core to what we do because of the performance advantages of in-memory data management, but it really is a subset -- we're not a caching vendor so to speak."

Have you looked at the CTP yet? Let me know your thoughts.

Gates Plugs SQL Server at Tech-Ed

"It's a very big release in terms of what people can do in the data center, how these various pieces connect together, different types of data that we can understand in a very rich way. And so this is central, and it's a big investment for us, something that is very key," Gates said.

Interestingly, he talked up how SQL Server is becoming the engine for other data-driven Microsoft platforms including Active Directory and even SharePoint. "Microsoft has always had a central focus on SQL Server as the place to store data," said Gates. "It's where we have the greatest capacity, the ability to distribute, update, query in very rich ways. In fact, what you see us doing is taking all our different data driven activities, and pushing them into SQL."

For example, now meta directory stored in Active Directory is SQL-based, where objects are replicated. Gates said in the future, Exchange will use the SQL store as well. While SharePoint already uses SQL, "we'll expose more and more of that native SQL power to the SharePoint developer for them to do easy application development," Gates said.

Gates was joined on stage by Dave Campbell, who talked up SQL Server 2008's spatial data as well as its support for file types.

Meanwhile, Gates also threw a bone to shops that use Visual Studio Team System that are managing apps developed for IBM's DB2 database. With the new support, developers will be able to perform DB2 development within Visual Studio.

Getting Ready For Tech-Ed Developers

While it remains to be seen what Gates may have to say about data-driven development, it wouldn't be surprising to hear him talk up Microsoft's Language-Integrated Query (LINQ) and Microsoft's "Oslo" project. Microsoft, of course, released LINQ with Visual Studio 2008 as a means of making it easier for developers to build database queries into their applications, and it's a significant extension to the .NET Framework. As for Oslo, Microsoft’s next-generation modeling platform for building service oriented architecture applications, it would be disappointing if some new details didn't emerge from Gates or chief software architect Ray Ozzie next week.

Regardless of what the big brass has to say, those interested in Oslo may want to check out Jon Flanders' "Framework and Microsoft BizTalk Best Practices with an Eye Toward Oslo" session on June 4th and David Chappell's "The Road to Oslo" session the following day.

If your interest is more down and dirty SQL Server development, Ward Pond, a technology architect in Microsoft's business online service delivery group's SQL Server Center of Excellence, points out he will be delivering several sessions that cover the gamut. Among them are "Set-Based Thinking for the OLTP Developer" on Tuesday June 3. A day later, Pond will be giving three more sessions: "SQL Tricks," "Data Modeling for OLTP," and "Version-Stamping of Database Objects."
