PEAR::DB is a database abstraction layer providing: * an OO-style query API * portability features that make programs written for one DBMS work with other DBMS's * a DSN (data source name) format for specifying database servers * prepare/execute (bind) emulation for databases that don't support it natively * a result object for each query response * portable error codes * sequence emulation * sequential and non-sequential row fetching as well as bulk fetching * formats fetched rows as associative arrays, ordered arrays or objects * row limit support * transactions support * table information interface * DocBook and phpDocumentor API documentation Drivers for the following extensions pass the complete test suite and provide interchangeability when all of DB's portability options are enabled: fbsql, ibase, informix, msql, mssql, mysql, mysqli, oci8, odbc, pgsql, sqlite and sybase.
