Writing WiredTiger applications

This section covers topics of interest for programmers writing WiredTiger applications.

We follow SQL terminology: a database is set of tables managed together. Tables consist of rows, where each row is a key and its associated value. Tables may optionally have an associated schema, splitting the value into a set of columns. Tables may also have associated indices, each of which is ordered by one or more columns.
