Administrative entities
- **Dataspace** is a primary logical separation of data.
and uniquely identified by its name (within its own dataspace). Same YANG resources (source files) can be
referenced by multiple schema sets from different dataspaces.
-- **Anchor** identifies the unique data set (data record) within a dataspace
+- **Anchor** identifies the unique data set (data record) within a dataspace.
Anchor always references a schema set within same dataspace which describes a data model of associated data.
Multiple anchors may reference same schema set. Anchor is uniquely identified by its name (within own dataspace).
Querying
-- **CPS Path** is used to query data nodes. The CPS Path is described in detail in :doc:`cps-path`.

+NCMP Modeling
+=============
+
+Data Model
+----------
+
+NCMP stores DMI-Plugin and CM Handle relations using a data model described as per this Yang module.
+
+:download:`DMI Yang Module <api/yang/dmiYangResource.yang>`
+
+Basic Concepts
+--------------
+
+- **CM-Handle** represents an instance a modeled Network Function(node) in ONAP.
+
+ These are stored as Anchors within CPS-Core.
+
+- **Datastores** represent different views of the cm data.
+
+ Datastores are defined for NCMP to access the CPS running or operational datastores. Currently supported datastores are:
+
+ +--------------------------------+-------------------------------------+-------------------------+
+ | Datastore | Configurations | Data access type |
+ +================================+=====================================+=========================+
+ | Passthrough-operational | config-true, config-false | read-only |
+ +--------------------------------+-------------------------------------+-------------------------+
+ | Passthrough-running | config-true | read-write |
+ +--------------------------------+-------------------------------------+-------------------------+
