RDBMS

Here’s another in the series of our internal talks, this time on our old friends, the relational database management systems — also known under their misleading alias — databases.
In the talk, I’ve explained some of the concepts of relational algebra and shown that if all our tables were indeed relations, the RDBMSs could do a lot of optimisations. For further reading, I recommend an excellent book by C. J. Date Database in Depth — Relational Theory for Practitioners.
