The CTU Prague Relational Learning Repository
Motl, Jan, Schulte, Oliver
The aim of the Prague Relational Learning Repository is to support machine learning research with multi-relational data. The repository currently contains 148 SQL databases hosted on a public MySQL server located at https://relational-data.org. The server is provided by getML to support the relational machine learning community(www.getml.com). A searchable meta-database provides metadata (e.g., the number of tables in the database, the number of rows and columns in the tables, the number of self-relationships). Many organizations maintain their data in relational databases, which support complex structured data.
