WSO2 moves data services component to OSGI-based Carbon framework

Moving to expand its user base to more database folks, WSO2 is releasing the promised data services component to Carbon, the open source company’s new modular service-oriented architecture (SOA) framework based on the OSGi component model.

WSO2 Data Services is “completely re-architected” for Carbon’s componentized approach to SOA development, which WSO2 debuted earlier this year. [Disclosure: WSO2 is a sponsor of BriefingsDirect podcasts.]

The new data services tools are aimed at database programmers and database administrators (DBAs), folks who may not be as familiar with WS-* style Web services, REST-style Web resources, data services, or OSGi as their Java coding brethren.

To help ease database folks into the brave new world of data services, WSO2 is offering free online training courses this month to “explain data services concepts and best practices for quickly exposing data as Web services.” In order to promote new thinking about enterprise data applications in the midst of a recession, WSO2 said it is waiving the $199 fee for the courses.

“WSO2 Data Services addresses the demand among enterprises to quickly and easily take data from a wide variety of sources and expose it as Web services within their SOAs,” Dr. Sanjiva Weerawarana, founder and CEO of WSO2, said in announcing the product.

DBAs may be asking: “How easy is easy?”

WSO2 answers that anyone who knows SQL can quickly create data services that can be shared and accessed across the network.

And you can even do some data service management from – we are not making this up –your cell phone.

This feature is courtesy of Data Services 2.0’s new extensible server administration framework that allows customization including writing a bridge application for management of data services servers from a Blackberry or other mobile device.

Since almost no enterprise SOA application is going to have just a single database, the WSO2 product supports a range of data sources. It works with relational databases including Oracle, MySQL and IBM DB2, as well as “virtually any database accessible via JDBC.” It can also work with the good old comma-separated values (CSV) file format, and Excel spreadsheets.

For DBAs and others with security concerns about where all this disparate data is coming from and where it’s going, WSO2 says services can be authenticated, encrypted and/or signed using the WS-Security and HTTP security standards. There is also a WS-Policy Editor for configuring services, as well as support for WS-ReliableMessaging.

Event-driven architecture (EDA) aficionados will find Data Services 2.0 support for events, including graphical declaration of event sources and mediation for event delivery.
