Data Catalog Navigation

The Data Catalog user interface enables users to move from one level to another through a data model’s graph, as well as to filter specific elements.

How Do I Access the Data Catalog?

The Data Catalog is accessed from the K2View Web Framework. Select the Data Catalog application from the Web Framework context menu. A display showing a project deployed to the OrientDB database will appear. If multiple projects have been deployed to the same OrientDB database, all projects will be displayed.

Data Catalog Legend

The Legend is displayed on the bottom right corner of the screen and provides a visual description of each component in the graph. The graph's data types can be split into the following categories:

Category Data Type Description
Project PROJECT Project name.
Target Components SCHEMA

Project entity (LU, Web Services or Common).

TABLE

LU tables.

API

Web service and its fields.

Source Components INTERFACE INTERFACE_SCHEMA INTERFACE_TABLE  Data source components.
Connection Lines


CONTAINED Indicates the data entity that holds the current entity. For example, if a table is contained in a Schema (LU).
USE Indicates the data entity used by the current entity. For example, if a TABLE (LU table) uses an INTERFACE_TABLE.
POPULATION_KEYS Indicates how the current table is populated in the LU schema. For example, when the relationship is ACTIVITY > CUSTOMER, the ACTIVITY table is populated using the key from the CUSTOMER table.

Click imageicon in the Legend to hide / unhide data elements in the tree.

How Do I Navigate Through the Data Catalog?

The following tools are used to navigate the Data Catalog:

  • Search the data element using the Search area in the top left corner of the screen. The search is performed using the search-as-you-type field type. The search results are presented in a table, enabling users to either add an entity to the tree or to replace the tree's focus to the selected entity.
