The Data Store Metadata is a database created to store metadata. It is a structure/index in which the actual data can be stored/written using an application such as ETL.

* Navigate to the ***Data Center*** ***Homepage***.
* Click the ***New*** menu.&#x20;
* Select the ***Data Store Metadata*** option from the ***New*** context menu.

* A new page asking for the ***Meta Store*** details opens.
* Enter a Data Store Name.
* Choose a ***Collection Name*** from the drop-down list (optional).
* Click the ***Next*** option.

* Define the data type (The user needs to insert the field name manually if the **Collection Name** is not chosen. Else, the names of the fields get selected from the chosen Collection). &#x20;
* The users can define the data for the ***Dimensions***, ***Measures***, and ***Time*** categories. The user can interchange the data categories of dimension, measure, and time value by using the below-given options:

* The ***Hierarchy Definition*** tab opens.          &#x20;
* Click the ***Add*** icon  provided in the Hierarchy Definition window.
* A new ***Drill Def*** box gets added to the page.
* Drag and drop the dimensions or time options to define a hierarchy.                   &#x20;
  * The time dimension creates a hierarchical sequence from the higher to lower time values by default. E.g., **year->month->date** by pulling it once in the ***Drill Def*** boxes.
  * Dimensions have to be manually pulled to create a hierarchy.
* Click the ***Next*** option. &#x20;

* Select a dimension from the drop-down menu to apply filter values to the data store.
* Enter a ***User Property*** to create a filter parameter based on the user.&#x20;
* Click the ***Finish*** option.   &#x20;
