CTI Python STIX2 provides the DataStore suites of [FileSystem](../api/datastore/stix2.datastore.filesystem.rst), [Memory](../api/datastore/stix2.datastore.memory.rst), and [TAXII](../api/datastore/stix2.datastore.taxii.rst).

"[CompositeDataSource](../api/stix2.datastore.rst#stix2.datastore.CompositeDataSource) is an available controller that can be used as a single interface to a set of defined [DataSources](../api/stix2.datastore.rst#stix2.datastore.DataSource). The purpose of this controller is allow for the grouping of [DataSources](../api/stix2.datastore.rst#stix2.datastore.DataSource) and making `get()`/`query()` calls to a set of DataSources in one API call. [CompositeDataSources](../api/stix2.datastore.rst#stix2.datastore.CompositeDataSource) can be used to organize/group [DataSources](../api/stix2.datastore.rst#stix2.datastore.DataSource), federate `get()`/`all_versions()`/`query()` calls, and reduce user code.\n",

"[CompositeDataSource](../api/stix2.datastore.rst#stix2.datastore.CompositeDataSource) is just a wrapper around a set of defined [DataSources](../api/stix2.datastore.rst#stix2.datastore.DataSource) (e.g. [FileSystemSource](../api/datastore/stix2.datastore.filesystem.rst#stix2.datastore.filesystem.FileSystemSource)) that federates `get()`/`all_versions()`/`query()` calls individually to each of the attached [DataSources](../api/stix2.datastore.rst#stix2.datastore.DataSource) , collects the results from each [DataSource](../api/stix2.datastore.rst#stix2.datastore.DataSource) and returns them.\n",

When `get()`/`all_versions()`/`query()` calls are made to the [CompositeDataSource](../api/stix2.datastore.rst#stix2.datastore.CompositeDataSource), it will pass along any query filters from the call and any of its own filters to the attached [DataSources](../api/stix2.datastore.rst#stix2.datastore.DataSource). In addition, those [DataSources](../api/stix2.datastore.rst#stix2.datastore.DataSource) may have their own attached filters as well.

"The CTI Python STIX2 DataStore suites - [FileSystem](../api/datastore/stix2.datastore.filesystem.rst), [Memory](../api/datastore/stix2.datastore.memory.rst), and [TAXII](../api/datastore/stix2.datastore.taxii.rst) - all use the [Filters](../api/datastore/stix2.datastore.filters.rst) module to allow for the querying of STIX content. The basic functionality is that filters can be created and supplied everytime to calls to `query()`, and/or attached to a [DataStore](../api/stix2.datastore.rst#stix2.datastore.DataStoreMixin) so that every future query placed to that [DataStore](../api/stix2.datastore.rst#stix2.datastore.DataStoreMixin) is evaluated against the attached filters, supplemented with any further filters supplied with the query call. Attached filters can also be removed from [DataStores](../api/stix2.datastore.rst#stix2.datastore.DataStoreMixin).\n",
