This document discusses relational databases in Pharo. It introduces Guille, a PhD student writing his thesis without using RDBMs. It then lists several database vendors and drivers that are available for Pharo, including Oracle, MSSQL, MySQL, PostgreSQL, SQLite, and ODBC. It describes Glorp, an ORM library for Pharo that is compatible with OpenDBX, Postgres V2, and NBSqlite3. Finally, it mentions that Glorp documentation is a work in progress and that Jenkins is used for continuous integration testing of OpenDBX, MySQL, PostgreSQL, SQLite, and Glorp on Windows, Linux, and 32-bit architectures.

4. Glorp
• Not the last version (available in VW)
• ~900 tests
• Compatible only with
OpenDBX, PostgresV2, NBSqlite3

(again, one driver to rule them all)
JDBC like (yes, sorry guys)
• But then, all drivers have different APIs
• Adapters or not?
• Forking? Breaking compatibility?
• Well, we are going there slowly

7. Jenkins
• Windows and Linux
• 32 bits for the moment
• OpenDBX, Native Mysql, Native Postgresql,
NBSqlite3, Glorp
