Database Abstraction Layer

A.6.1.1 Description

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 PHPDoc API documentation

DB layers itself on top of PHP's existing database extensions. The currently supported extensions are: dbase, fbsql, interbase, informix, msql, mssql, mysql, mysqli, oci8, odbc, pgsql, sqlite and sybase.

DB is compatible with both PHP 4 and PHP 5.

db++ database functions

A.6.4.1 Description

db++, made by the German company Concept asa, is a relational database system with high performance and low memory and disk usage in mind. While providing SQL as an additional language interface, it is not really a SQL database in the first place but provides its own AQL query language which is much more influenced by the relational algebra then SQL is.

A.6.5. DB_ado

Repository: PEAR - License: LGPL - By Alexios Fakos (lead)

DB driver which use MS ADODB library

A.6.5.1 Description

A.6.6. DB_DataObject

Repository: PEAR - License: PHP License - By Alan Knowles (lead)

An SQL Builder, Object Interface to Database Tables

A.6.6.1 Description

DataObject performs 2 tasks:

  1. Builds SQL statements based on the objects vars and the builder methods.

  2. acts as a datastore for a table row.

The core class is designed to be extended for each of your tables so that you put the data logic inside the data classes. included is a Generator to make your configuration files and your base classes. nd

A.6.7. DB_DataObject_FormBuilder

Repository: PEAR - License: PHP License - By Markus Wolff (lead)

Class to automatically build HTML_QuickForm objects from a DB_DataObject-derived class

A.6.7.1 Description

DB_DataObject_FormBuilder will aid you in rapid application development using the packages DB_DataObject and HTML_QuickForm. For having a quick but working prototype of your application, simply model the database, run DataObject´s createTable script over it and write a script that passes one of the resulting objects to the FormBuilder class. The FormBuilder will automatically generate a simple but working HTML_QuickForm object that you can use to test your application. It also provides a processing method that will automatically detect if an insert() or update() command has to be executed after the form has been submitted. If you have set up DataObject´s links.ini file correctly, it will also automatically detect if a table field is a foreign key and will populate a selectbox with the linked table´s entries. There are many optional parameters that you can place in your DataObjects.ini or in the properties of your derived classes, that you can use to fine-tune the form-generation, gradually turning the prototypes into fully-featured forms, and you can take control at any stage of the process.

  • support for NotNull, Indexes, Sequences , Unique Indexes and defaults

  • works totally in non-connected mode (eg. no database or setting up required)

  • stores in MDB like xml file.

  • saves to any supported database SQL create tables files.
