Pervasive PSQL

Pervasive PSQL is an ACID-compliant database management system (DBMS) developed by Pervasive Software. It is optimized for embedding in applications and used in several different types of packaged software applications offered by independent software vendors (ISVs) and original equipment manufacturers (OEMs). It is available for software as a service (SaaS) deployment due to a file-based architecture enabling partitioning of data for multitenancy needs.

Applications can store the data and the relationships in tables in a relational model (RDBMS) or store the data in a schema-less way with no fixed data model (key-value store).

Pervasive PSQL runs on system platforms that include Microsoft Windows, Linux, and Mac OS X. Both 32-bit and 64-bit editions of Pervasive PSQL are available. Editions are also specifically designed for different computer networking deployment needs, such as workgroup, client-server, and highly virtualized environments, including Cloud computing.

The original name for Pervasive PSQL was Btrieve. Pervasive Software was acquired by Actian Corporation in 2013.
