SchemaCrawler has a good mix of useful features for data governance. You can [search for database schema objects](https://www.schemacrawler.com/schemacrawler-grep.html) using regular expressions, and output the schema and data in a readable text format. The output serves for database documentation, and is designed to be [diff-ed](https://en.wikipedia.org/wiki/Diff) against other database schemas. SchemaCrawler also generates [schema diagrams.](https://www.schemacrawler.com/diagramming.html) You can [execute scripts](https://www.schemacrawler.com/scripting.html) in any standard scripting language against your database. You can find potential schema design issues with [lint](https://www.schemacrawler.com/lint.html). SchemaCrawler can also generate structured database documentation in [Google OKF format](https://github.com/GoogleCloudPlatform/knowledge-catalog/blob/d44368c15e38e7c92481c5992e4f9b5b421a801d/okf/SPEC.md) using [SchemaCrawler Scribe](https://www.schemacrawler.com/scribe.html). SchemaCrawler supports almost any database that has a JDBC driver, but for convenience is [bundled with drivers](https://www.schemacrawler.com/database-support.html) for some commonly used RDBMS systems. SchemaCrawler works with any operating system that supports Java SE 17 or better. [SchemaCrawler is also a Java API](https://dev.to/sualeh/how-to-get-database-metadata-as-java-pojos-24li) that makes working with database metadata as easy as working with plain old Java objects. > The [SchemaCrawler-Core](https://github.com/schemacrawler/SchemaCrawler-Core) API and tools framework code is available as a separate GitHub project. ## Licensing SchemaCrawler is available under a number of [licenses](https://www.schemacrawler.com/license.html). ## Distributions and Downloads Explore the SchemaCrawler command-line with a [live online tutorial](https://killercoda.com/schemacrawler).
