Database documentation tools

List of tools that allow the documentation (e.g. with descriptions) of schema of your databases.

Database documentation is a set of descriptions of the data, that facilitate management, maintenance, and retrieval of resources. Documentation can take many forms, however, it usually acts as a data catalog that holds detailed information about the table schema, all relationships, data types, etc. Description of datasets as well as single data objects also is referred to as metadata (data about the data).

Database documentation tools support data management by creating helpful descriptions, meaningful aliases, and annotating data assets with additional elements. The tools capture all the relevant information about the metadata and make it available to the users in a convenient way (tabular or graphical). The features of documentation tools can vary widely. The tools allow users to:
• Facilitate datasets with meaningful descriptions/aliases,
• Create relational diagrams,
• Advance search of resources,
• Track schema changes,
• Document repositories from various sources, through compatibility with many database engines,
• Automatic documentation export to user-friendly formats and easy-to-share formats (HTML, PDF, Excell )

Developers (especially those working on the backend) are constantly faced with questions from non-IT teams or customers about what a given object means. This is because creating and maintaining documentation is not a top priority. However, using documentation tools has many benefits such as:
• Help Data stewards quickly discover database schema,
• Data becomes understandable for non-IT members,
• Documentation as a single source of truth about the data is available to everyone
• Easier implementation for new people working on the repository,

We have selected database documenters that, we believe, are truly noteworthy. We have included both, open-source tools and advanced, professional software (offering trial versions).
