Yet Analytics SQL LRS

A SQL-based Learning Record Store.

What is SQL LRS?

A Learning Record Store (LRS) is a persistent store for xAPI statements and associated attachments and documents. The full LRS specification can be found in Part 3 of the xAPI specification. SQL LRS is distinct from other LRSs developed at Yet Analytics for being SQL-based and supporting multiple SQL database management systems (DBMSs) like SQLite and Postgres.
