Mozilla Firefox name conflict

Storage and index technology

The Multi-Generational Architecture (MGA)

Firebird inherited the storage architecture of Interbase. To ensure the ACID properties of transactions, the database engine keeps different versions of each record changed by the active users in the database. When the transactions are committed, the last version of every changed record is marked as the definitive. If transactions are rolled back, the database engine keeps the mark on the original record versions, leaving them untouched.WEB,weblink Multi-generational architecture (MGA) and record versioning, HK-Software, 14 July 2011, As a result, Firebird disk writes are very reduced compared to databases that use the traditional transaction log architecture.WEB,weblink Interview with Jim Starkey from InterBase World, Marina Novikova, InterBase World, 14 July 2011, Writing transactions does not prevent reading and vice versa, because each one sees its own version of the database.WEB,weblink What is Multi Generational Architecture (MGA)?, The Firebird FAQ, 14 July 2011, The tradeoff is that some maintenance (“sweeping”) is required from time to time to clean up old record versions and free disk space.WEB,weblink Database Housekeeping And Garbage Collection, The Firebird Project, 14 July 2011, The multi-generational architecture ensures that OLTP and DSS/OLAP operations can be run simultaneously without the delays caused by locking mechanisms found in other products.WEB,weblink What is Multi Generational Architecture (MGA)?, The Firebird FAQ, 14 July 2011,

Indexes

Firebird makes all indices of the database behave like well-tuned “clustered indexes” used by other architectures. Firebird index buckets aren’t subject to two-phase locking, and boolean “and” and “or” operations can be performed on intermediate bitmaps at a negligible cost, eliminating the need for the optimizer to choose between alternative indexes.WEB,weblink Interview with Jim Starkey from InterBase World, Marina Novikova, InterBase World, 14 July 2011,

Variants

  • Firebird SuperServer has a single daemon/server for all client connections, multithreaded with shared cache
  • Firebird SuperClassic also has a single daemon/server for all client connections, multithreaded with separate caches
  • Firebird Classic uses inetd to run one copy of the server per client connection, recommended for SMP systems but might have event-notification issues if access is via a firewall
  • Firebird Embedded for creating CD-ROM catalogs, single user or evaluation versions of applications

Licensing

The Firebird database engine and its modules are released under an open-source license, the Initial Developer's Public License (IDPL), a variant of the Mozilla Public License (MPL) version 1.1. It does not require the developer to open the products using Firebird or even custom-derivatives made from its source code, but if the developer chooses to do so, then some terms and conditions should be honored. The IDPL allows the developer to make proprietary, closed-source applications that use Firebird or are based on it.WEB,weblink Firebird: Initial Developer's Public License Version 1.0, Firebird Project, 13 July 2011,

Connectivity APIs

Low-level Firebird Native API, Services API and embedded SQL

The Firebird native API is used directly or indirectly by applications or middleware that connect to a Firebird database. It is implemented in the client library, fbclient.dll, on Windows systems, and in libfbclient.so on Unix ones.WEB,weblink The Firebird client library, The Firebird Project, 14 July 2011, The Services API is a special function set for accessing and controlling service administration tasks such as user management, backup/restore and statistics gathering.Embedded SQL is a technique that simplifies the development of C/C++ and COBOL Firebird applications, by using a preprocessor called gpre, which allows the embedding of SQL statements directly into the source code of the host language.WEB,weblink Application development, The Firebird Project, 14 July 2011,
