Description

Author

Manuel Lemos

Package of classes that provide DBMS independent access and management of databases.

Currently it features:

o BSD style license.

o Dual API call forms:
* Direct driver class object calls
* Global function calls

o Set of functions that call the selected DBMS driver objects functions supporting when possible:
* Database connection setup with support for connection strings
* Operation error handling
* Query constant data conversion
* Direct queries
* Prepared queries
* Query result rows random access
* Retrieve a limit range of rows of a SELECT query.
* Nested transactions
* Large object fields (BLOBs - storing files in the database)
* Database object creation (tables, indexes, sequences)
* DBMS driver supported feature query

o DBMS Drivers classes that support the most important databases being used on the Web.

o Driver conformance test suite to verify if the driver classes are working and features are properly implemented.

o A parser class that is able to interpret DBMS independent database schemas file defined in a custom XML format supporting the following types of objects:
* Tables with fields of the types: text, integer, boolean, date, time, timestamp, decimal, float, character large objects (CLOBs) and binary large objects (BLOBs), auto-increment.
* Primary keys
* Indexes
* Auto incremented sequences

o A manager class that is able to:
* Install a new database from a schema description interpreted by the parser class.
* Ability to compare a previously installed schema with a new schema and only install the changes without affecting data stored after the previous installation or update.
* Dump database structure and contents in the same XML format handled by the parser allowing for moving data between databases of different DBMS vendors.
* Reverse engineer schemas of already installed databases

o Driver classes for multiple databases:

* MySQL using the traditional MySQL extension or MySQLi
* PostgreSQL
* Oracle using oci extension
* Microsoft SQL server using the mssql extension
* SQLite
* Generic ODBC base driver
* MS Access using ODBC
* Interbase
* Informix
* MiniSQL

Obliquid is a PHP and XML based framework for building groupware Web portals. It provides "Lego bricks" that may be composed to build an Internet application. Metabase was chosen after experiencing database portability problems with others database abstraction layers. Metabase is also used also to install the database schema.
Database independent Web hit counter and manager.
phpSecurityAdmin is a package for managing user accounts and access rights. Metabase was used due to its extensive database driver support and its API that is meant to provide portability to the database packages like this.
