The Concourse data model is lightweight and flexible. It can support any kind of data at very large scales. Concourse trades unnecessary structural notions of schemas and tables for a more natural modeling of data based solely on the following concepts:

Record - A logical grouping of data about a single person, place or thing (i.e. an object). Each record is a multimap of key/value associations that are together identified by a unique Primary Key.
Key - An attribute that maps to one or more distinct values. A record can have many different keys. And the keys in one record do not affect the keys in any other record.
Value - A dynamically typed quantity that is mapped from a key in a record.

Data Types

Concourse natively stores boolean, double, float, integer, long and string (UTF-8) data.

Links

Concourse supports the ability to link one record to another. This is accomplished by adding the primary key of the destination record as a value to a key in the source record.
