Database Abstraction Layer is a project to produce a general way to access databases from within PHP. The DAL class takes care of the administration involved with the different kinds of databases. DAL is extendible via plugins so support for different dbms' can be added dynamicly. Also switching from one DBMS to another is simple because not very much has to be altered to support the new DBMS.
SQLConnect is a JDBC connectivity tool that allows the user to browse, query, edit, export, and print data from any JDBC compliant database. It has a rich set of data editing and data manipulation functionality that allows the user not only to query the JDBC database, but also to change its structure and model without writing complex and awkward SQL statements.
PHP/Toolbox is designed to make the process of creating database-powered Websites easier. It utilizes the iterative, or step-by-step development paradigm. It therefore enables you to create fully-functional Web interfaces for an arbitrary set of DB tables within minutes. Any changes you make in these tables after the test driving will be handled automatically. You can then adjust this automatic interface in an iterative manner to suit your specific needs.
