With Perst, Silverlight Gains Embedded Database and Secure Local Storage

McObject® announced it has successfully ported Perst™, its open source, object-oriented embedded database system, to Microsoft’s Silverlight technology for building rich Web applications. With Perst for .NET, developers using Silverlight can now include true database management system (DBMS) features in their rich Web client applications, including adding persistence to this data by storing it on local file systems. Visit the Perst product portal for complete feature and specification details

Data stored in Perst can exceed the storage size limit initially imposed on Silverlight applications, although for security reasons, permission from the Web application user is required for this. Permitting substantial amounts of locally stored data makes Perst a logical choice for Silverlight-based software-as-a-service (SaaS) and other hosted applications that need a database to support users’ work on ongoing projects.

Microsoft has also positioned Silverlight as a platform for rich Internet applications on smartphones and other mobile devices. “Perst’s strengths – including its small footprint, rich data management features, successful track record in a variety of mobile applications, and freely available source code – give it an edge to become the de facto embedded database system for Silverlight client software targeting mobile devices,” McObject CEO Steve Graves said.

McObject also released a new demo, available atwww.mcobject.com/silverlight-demo, showcasing Perst in a Silverlight-based customer relationship management (CRM) system. The demo runs in the user’s browser, stores records locally, and takes full advantage of Perst features such as indexes and native full text search to sort, retrieve and write records to the database. Users can launch the application from McObject’s site and also download complete, commented source code and documentation.
