DEPS (formerly known as graph-includes) is a set of tools and libraries which allows users to extract dependency information from arbitrary material (e.g. program source files), apply various transformations to this graph, and draw it. It is typically used as helper tool for a refactoring effort, to create a graph of dependencies between groups of source files. Readability and usability of the dependency graphs are currently improved by customizable grouping of several source files into a single node, coloring of nodes belonging to given groups, and transitive reduction of the graph.
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.
Autodia is a command line Perl application that generates UML class diagrams from source code, SQL, and database connections. It supports multiple programming languages including SQL, and can output images (using GraphViz/VCG/SpringGraph), Dia XML and Umbrello XML, or custom formats using templates.
