# Creating a New Meta Data Store

There are two ways to create Data Store Meta Data:

1. By mapping to an existing Collection
2. Without mapping to any existing Collection

## Creation by Mapping to an Existing Collection <a href="#creation-by-mapping-to-an-existing-collection" id="creation-by-mapping-to-an-existing-collection"></a>

The Data Store Metadata can be created by mapping it with an existing collection. In this case, it will display the data of the mapped collection.

* Navigate to the ***Data Center*** ***Homepage***.
* Click the ***New*** menu.
* Select the ***Data Store Meta Data*** option from the ***New*** context menu.

* A new page asking for the ***Meta Store*** details opens.
* Enter a Data Store Name.
* Provide the Description of the Data Store Meta Data.
* Choose a ***Collection Name*** from the drop-down list (optional). In this case, a collection has been selected.
* Click the ***Next*** option.

* The names of the fields get selected from the chosen Collection.
* The user also gets 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:

* Click the ***Next*** option.

* The ***Hierarchy Definition*** tab opens.
* 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.
  * 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.

* The ***Data Restrictions*** tab opens. The Data Restriction tab allows the user/user group to access data as per the selected ***User Property*** options.
* Click the **Add** icon to insert new fields for ***Dimension*** and ***User Property***.
* 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.
* Click the ***Finish*** option.

* A notification message appears to confirm the configuration of the new Meta Data.
* The newly created ***Meta Data*** gets added to the list displayed on the left pane of the page.

## Creation without Mapping to any Existing Collection

The Data Store Metadata can be a structure/index in which the actual data can be stored/written using an application such as Data Pipeline. In this case, there will be user defined structure without actual data in it.

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

<figure><img src="https://content.gitbook.com/content/TEE47Mdie26Zlpy6Ko2H/blobs/7cjsGYepguNQz2WmJhoh/image.png" alt=""><figcaption></figcaption></figure>

* A new page asking for the ***Meta Store*** details opens.
* Enter a Data Store Name.
* Choose no ***Collection Name*** from the drop-down list.&#x20;
* Click the ***Next*** option.

* Define the data type to insert the field name manually since the **Collection Name** is not chosen.&#x20;
* The users can define the data for the ***Dimensions***, ***Measures***, and ***Time*** categories. The user can even interchange the data categories of dimension, measure, and time value by using the below-given options:
  * Provide a title for Dimensions, Measures, or Time  entities.
  * Use the Add icon to add the defined Dimension, Measure and Time values.
