Indexes are a basic feature of relational databases. PostgreSQL offers a rich collection of index options for developers and designers. But users need to understand the basic concept of indexes, to be able to compare the different index types and how they apply to different application scenarios. Only then can you make the best decisions about index strategy and design. 

This course consists of 13 short videos. Pass a brief quiz afterward and receive a Certificate of Completion from Percona. Begin the course on Google Classroom here. If you’re prompted for a class identifier, enter code xk5k6fz. The lesson list:
