基于PHP實現的數據庫模型版本控制，deltasql 1.4.2 發布

新版本改進了可視化效果，在一些重要的功能上提供了圖標指示，為空的單元格提供邊框顯示，修復了一些小bug。

deltasql 是一個高級的數據庫模型版本控制軟件，類似于 cvs 和 svn 。它可以讓一個團隊同時開發一個數據模型，該工具目前支持的數據庫包括：MySQL, PostgreSQL 和 Oracle。
它具有以下特性：

• Deltasql server manages SQL scripts which alter database structure and contents. It organizes scripts in modules, which can be grouped in projects. It allows to search among them.
• Database synchronization by adding special synchronization table to each schema. Synchronization script generated by deltasql server. Handling of branches of branches and tags supported.
• Verification step inside synchronization script to ensure script is executed on correct schema (available for Oracle and PostgreSQL).
• Several teams of developers can manage several projects and several databases.
• Ability to manage development schemas and production schemas by creating branches, branches of branches and tags.
• Syncronization scripts can be generated for Oracle, postgreSQL, mySQL, Microsoft SQL Server and sqlite. On user request, any SQL-like database can be supported.
• Synchronization script can be exported in several formats, including pretty printed HTML, text and XML or even a zipped package with each script stored in a file.
• Free to use, Open Source tool licensed under GPL.
• Integration on Windows platform (XP, 7) with multipurpose deltaclient tool.
• Integration in Eclipse IDE with ant client or dbredactor client.
• Bash client can perform continouus database integration on Linux.
• RSS feed and iGoogle Gadget show latest submitted scripts.
• Easy to install, like a webforum, as deltasql server runs on Apache/PHP backed by a mySQL database.
• There is a manual, a list of frequently asked questions and a set of tutorial movies explaining how it works.
• It is used productively by companies in Pakistan, USA, Italy, Switzerland and India and is popular in Japan and South Korea. In some companies it manages more than 2000 scripts and more than 10 projects.
• Typically used for large J2EE/Oracle software architectures which are partially customized to the customer's wishes.
• Lightweight, fast and reliable :-)
