InterBase is a light-weight, embeddable, cross-platform Relational Database Management System. InterBase is characterized by its small footprint, minimal administration and built-in data security control.
InterBase was originally developed by Jim Starkey in 1984 as a RDBMS utilizing multi-generational architecture. InterBase was acquired by Borland Inc. in 1991. In 2000, an open-source DBMS called FireBird was forked from InterBase. InterBase, along with other development tools, are purchased by Embarcadero Technologies, Inc.
InterBase supports virtual views. Views are not materialized.
InterBase is the first DBMS that implements Multi-Version Concurrency Control (MVCC). MVCC is referred to as Multi-Generational Architecture in InterBase.
InterBase uses an optimizer to estimate costs of different joining orders and to generate data retrieval plan. Merge-Sort Join and Nested Loop Join are supported. InterBase also allows users to specify customized plan by using PLAN clause.
Three isolation levels are supported: SNAPSHOT, SNAPSHOT TABLE STABILITY, READ COMMITTED.
InterBase uses a variant of B-tree for index structure. Indices are automatically created for PRIMARY KEY, FOREIGN KEY and UNIQUE attributes.
InterBase supports foreign keys and creates indices for foreign keys by default. Referential integrity is enforced for foreign keys.
InterBase is a relational database management system (RDBMS) and it complies with SQL-92 standard.
InterBase can be used as a server which adopts Shared-Everything architecture, or as an embedded library.
In index, data values are compressed via pre and postfix compression.
