Pervasive Software has started shipping version 4.0 of its Scaleable SQL embedded database for low footprint platforms such as laptops.
The supplier - formerly Novell subsidiary Btrieve - has traditionally sold its Btrieve navigational database and Scaleable SQL relational database through the third party channel.
Bo Holland, Pervasive?s director of product marketing, said the firm had rewritten the file system in Scaleable SQL 4.0 to support up to 54Gbytes rather than the previous 4Gbytes, with the aim of removing former limitations in memory and scaleability.
As a result, the company has included conversion utilities in the product free of charge to help people migrate their existing applications.
The new version of Scaleable SQL also includes Inscribe, a Visual Basic-compatible scripting tool to enable developers to write business rules and stored procedures for building partitioned applications.
Inscribe also enables programmers to customise applications more easily - if they script their business rules into the database, they will automatically be mirrored in the application.
Other new features include nested transactions and TCP/IP support. The latter will enable Scaleable SQL-based applications to hook seamlessly into a Unix environment for the first time - something, according to Holland, that has become increasingly important since the database was ported to Windows NT as an additional platform to Novell?s Netware.
Pervasive was spun out of Novell in April 1994, and kept its former Btrieve name until last July, when it was renamed to try to de-emphasise the close links with its former parent.
