############ Introduction ############ The Aerospike Python client enables you to build an application in Python with an Aerospike cluster as its database. The client manages the connections to the cluster and handles the transactions performed against it. The Python client is a CPython module built on the Aerospike C client. .. rubric:: Data Model At the top is the **namespace**, a container that has one set of policy rules for all its data, and is similar to the *database* concept in an RDBMS, only distributed across the cluster. A namespace is subdivided into **sets**, similar to *tables*. Pairs of key-value data called **bins** make up **records**, similar to *columns* of a *row* in a standard RDBMS. Aerospike is schema-less, meaning that you do not need to define your bins in advance. Records are uniquely identified by their key, and record metadata is contained in an in-memory primary index. .. seealso:: `Architecture Overview `_ and `Aerospike Data Model `_ for more information about Aerospike.
