  1. Databases

  2. Purpose of the Database • Managing Web Content • Executing Transactions

  3. Database Management Systems (DBMS) • Commercial • Open Source

  4. Commercial DBMS • Oracle • Access • Microsoft SQL Server • DB2 • Sybase • Buyers Guide • http://www.dbmsmag.com/pcdbms.html#P1107

  5. Oracle • http://www.oracle.com/start/portals/intro.html?src=201777&Act=67

  6. Access • http://www.microsoft.com/office/access/default.htm

  7. Microsoft SQL Server • http://www.microsoft.com/sql/ • Open Database Connectivity (ODBC) is a widely accepted application programming interface (API) for database access. It is based on the Call-Level Interface (CLI) specifications from X/Open and ISO/IEC for database APIs and uses Structured Query Language (SQL) as its database access language.

  8. Sybase • Scalability • http://www.sybase.com/products/databaseservers

  9. Open Source DBMS • MySQL • PostgreSQL • InterBase • db.linux = Centura • http://www.codecatalog.com/

  10. MySQL • Launched January 1998 • Primarily for managing web content • Transaction processing by end 2001 • Up to 10,000 records

  11. PostgreSQL • Michael Stonebreaker UC Berkeley • Great scalability • Runs on large number of platforms • Image of the DB is dumped to text file • Backup and Recovery Features missing • No Journaling-automated recovery • No Replication-update of remote copies

  12. InterBase • A mature relational system, InterBase, is already in use by such large commercial customers as Bear Stearns, Boeing, The Money Store, Motorola and Nokia. • InterBase, has backup and recovery mechanisms that function much like the automated processes of commercial database systems. But its replication is supplied via a third-party add-on engine from Synectics Software, a South African firm. • InterBase is entry level SQL-92 compliant

  13. db.linux • Centura Software-Open Source • http://www.dbstar.org/

  14. SQL92 • the latest standard for accessing data in relational databases; • compliance is gauged in three stages: entry level, intermediate and high level. • Entry level achieved by commercial DBMS • Nobody is fullySQL92 compliant

  15. SQL • http://www.sql.org • http://www.dbasupport.com/

  16. Tutorials • http://searchdatabase.techtarget.com/bestWebLinks/0,289521,sid13_tax281630,00.html • http://www.builder.com/Programming/ChoosingWebDB/ • CIA-Handbook • http://www.dcs.napier.ac.uk/~andrew/sql/
