B-tree Indexes in Databases Using .NET Entity Framework and PostgreSQL as Examples

A talk about how regualr™ indexes work in databases. It will be extremely useful both for those who start working with databases, and for those who have database experience. The talk will describe the way you could use database indices to make SQL faster. The samples will use PostgreSQL, however the knowledge will also apply to many other databases, because the b-tree algorithm was invented in 1970, and its variations are used very often now.
