'''H2''' - [[Java (Бағдарламалау тілі)|Java]] бағдарламалау тілінде жазылған реляциялық [[мәліметтер қорын басқару]] жүйесі.<!-- written in [[Java (programming language)|Java]]. It can be embedded in Java applications or run in the client-server mode.<ref>{{cite web | title=Presentation and use of H2 Database Engine | url=http://www.baptiste-wicht.com/2010/08/presentation-usage-h2-database-engine/}}</ref> The disk footprint (size of the [[JAR (file format)|jar file]]) is about 1 MB.--><ref>{{cite web | title=Jar File Download | url=http://repo2.maven.org/maven2/com/h2database/h2/}}</ref><br />

== Сипаттамалары ==<br />
[[SQL]] тілінде бағдарламаланады. Қосымшалар бағдарламалау интерфейстері (APIs): [[SQL]] және [[JDBC]], сонымен қатар мәліметтер базасы [[PostgreSQL]] [[ODBC]] драйверін [[PostgreSQL]] сервері ретінде жұмыс істелінеді.<ref>{{cite web | title=H2 Database supports PostgreSQL ODBC driver | url=http://www.theserverside.com/news/thread.tss?thread_id=46456}}</ref><br />

It is possible to create both in-memory tables, as well as disk-based tables. Tables can be persistent or temporary. Index types are hash table and tree for in-memory tables, and [[b-tree]] for disk-based tables. All data manipulation operations are [[Database transaction|transactional]]. Table level locking and [[multiversion concurrency control]] are implemented. The [[2-phase commit]] protocol is supported as well, but no standard API for distributed transactions is implemented. The security features of the database are: [[Access control#Role-based access control|role based]] access rights, encryption of the password using [[SHA-256]] and data using the [[Advanced Encryption Standard|AES]] or the Tiny Encryption Algorithm, [[XTEA]]. The cryptographic features are available as functions inside the database as well. [[Secure Sockets Layer|SSL]] / [[Transport Layer Security|TLS]] connections are supported in the client-server mode, as well as when using the console application.<br />
<br />
Two [[full text search]] implementations are included, a native implementation and one using [[Lucene]].<br />
<br />
A simple form of high availability is implemented: when used in the client-server mode, the database engine supports hot failover (this is commonly known as clustering). However, the clustering mode must be enabled manually after a failure.<ref>{{cite web | title=H2 Clustering | url=http://geowebcache.org/trac/wiki/external_h2db#H2clustering}}</ref><br />
<br />
The database supports protection against [[SQL injection]] by enforcing the use of parameterized statements. In H2, this feature is called 'disabling literals'.<ref>{{cite web | title=SQL Injections: How Not To Get Stuck | url=http://thecodist.com/article/sql-injections-how-not-to-get}}</ref><br />
<br />
Since version 1.1.111, H2 [[in-memory database]] can run inside the [[Google App Engine]].<ref>{{cite web | title=H2 Database on GAE | publisher=gaevfs | url=http://code.google.com/p/gaevfs/wiki/H2GAE}}</ref><br />
