InterBase

Checkpoints[03]

Checkpoint (also called Journaling Checkpoint) is supported in InterBase.

Compression[04]

Run-Length Encoding Prefix Compression

In index, data values are compressed via pre and postfix compression.

Concurrency Control[05]

Multi-version Concurrency Control (MVCC)

InterBase implements Multi-Version Concurrency Control (MVCC) and refers to it as Multi-Generational Architecture.

Data Model[06]

Relational

InterBase is a relational database management system (RDBMS) and it complies with SQL-92 standard.

Foreign Keys[07]

Supported

InterBase supports foreign keys and creates indices for foreign keys by default. Referential integrity is enforced for foreign keys.

Indexes[08][04]

B+Tree

InterBase uses a variant of B-tree for index structure. Indices are automatically created for PRIMARY KEY, FOREIGN KEY and UNIQUE attributes.

Isolation Levels[09]

Read Committed Snapshot Isolation

Three isolation levels are supported: SNAPSHOT, SNAPSHOT TABLE STABILITY, READ COMMITTED.

Joins[10][11]

Nested Loop Join Sort-Merge Join

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.
