LiquiBase is a DBMS-independent library for tracking, managing, and applying database changes. It is built on a simple premise: all database changes (structure and data) are stored in an XML-based descriptive manner and checked into source control. While there have been many attempts to provide a similar tool, LiquiBase aims to provide a solution that supports merging of changes from multiple developers, works well with code branches, supports a database refactoring IDE/plugin, and more.
The PKP Open Archives Harvester is a free metadata indexing system intended to expand and improve access to research. The PKP OAI Harvester allows you to create a searchable index of the metadata from Open Archives Initiative (OAI)-compliant archives, such as sites using Open Journal Systems (OJS) or Open Conference Systems (OCS).
Essential Management is a multi-user project management system for managing intricate and complex information. Its initial purpose was to allow software development teams to create, maintain, track, and store project requirements on a multi-project basis in a multi-user environment. It has now become more abstract in the type of data it can maintain, allowing the easy addition of new data models and other expansions. Information can be stored in any of several database management systems, and can take advantage of a networked DBMS.
cstor is a cross-reference compiler and reverse engineering tool. It compiles one text file (database) from multiple source modules (currently reads C, C++, and Perl). The tool combines reverse engineering capabilities, code validation, and an HTML documentation generator. The database can then be reused from own scripts and programs, e.g. to implement cross-compilers, validate coding conventions, build statistics etc. The builtin documentation generators are actually an application of the database.
Dico is a Java application to display database schema. It allows importing database schema from an existing database (Oracle, Microsoft SQL Server, MySQL, and PostgreSQL), offers a customizable display of tables and relationships, and allows you to print to any system printer and export to various formats (PDF, EMF, SVG, and others).
XML to DDL is a set of Python programs that converts an XML representation of a database into a set of SQL or DDL (Data Definition Language) commands. In addition, it can examine the difference between two XML files and output a sequence of SQL statements (normally ALTER statements) to bring one database up-to-date with the XML schema. You can also download the XML schema directly from the database. Finally, there's a tool to convert your schema into HTML for documentation purposes. XML to DDL currently supports the most recent versions of PostgreSQL, MySQL, Oracle, and Firebird databases.
alph implements and analyzes historical and traditional ciphers and codes, such as polyalphabetic, substitutional, and mixed employing human-reconstructable algorithms. It provides a pipe filter interface in order to encrypt and decrypt block text to achieve transparency. The program is meant to be used in conjunction with external programs that transfer data, resulting in transparent encryption or decryption of information. The program can thus be used as a mail filter, IRC filter, IM filter, and so on.
