Metastorage 2007.09.19

Metastorage is a PHP data access object generator compiler tool.
Metastorage is a PHP data access object generator compiler tool.

Metastorage is an application that automatically generates code for an Object Oriented API to store, retrieve and manipulate the persistent objects of classes described in a high level data model definition.

Metastorage provides a much more efficient development process for medium or large size applications that store and retrieve data from SQL based databases or other types of storage persistence containers, like XML files, flat file databases or LDAP servers.

When storing objects in SQL databases, Metastorage generated code performs efficient object-relational mapping. Metastorage antecipates static storage optimization decisions at compile time, so applications gain in performance, code size and memory usage by avoiding evaluating static decisions at run time.

Here are some key features of "Metastorage":

XML definition format

· Easy to write and understand component definition format in XML

Database schemas

· Automatic generation of (database) schema definition of the persistence container

Automatic generation of all classes

· Generates all the code for the data classes, factory class and (database) schema installation class

Self-contained code

· The generated code is self-contained and does not depend on MetaL or libraries of code that are not supplied

Object Query Language

· Provides an Object Query Language (OQL) to define expressions to filter objects in search queries

No SQL

· All code is generated without the need for the developer to write SQL code manually

Forms

· Generation of classes to create, validate and process Web forms to manage objects of the data classes.

Reports

· Generation of classes to execute queries to retrieve data from many objects to elaborate reports or to execute another kind of bulk processing

UML Diagrams

· Automatic generation of Entity-Relationship graphs in UML of the component class diagram

Requirements:

· Metastorage is an application of the MetaL compiler engine. This engine is totally written in PHP.

· The MetaL engine requires PHP 3 or later to run. The code generated by Metastorage requires PHP 4 or later to run. Any platform on which PHP 4 is supported can run Metastorage and the generated code, including: Linux, Windows, Mac OS X, Solaris, etc..

· Metastorage can be run either from the command line (shell/DOS) or using Webstorage - the Web interface (recommended). Webstorage requires a Web server supported by PHP, including Apache, Microsoft IIS, Netscape Server, etc.

What's New in This Release:

· This release introduces the capability of generating a new type of function to create a copy of an existing persistent object in memory.
· The generation of form processing classes for creating new objects was enhanced to support classes with variables of types boolean, integer, decimal, and float.
· This release also includes several minor bugfixes.
