But let's get a bit thorough on this. Normally, we are usually introduced to Relational Databases, like MS Access. Those are primarily SQL based languages. They have tables in which data is stored. Each table has multiple rows, and each row has multiple columns or fields. The data stored follows a well defined schema. Moreover, relations can be set-up between various tables, so that redundant data is not stored. One of the main advantages is that we can thus change the data in only one location and the effects are observed everywhere.

Instead of tables, it has what are called as "Collections", though o
