      SAP HANA

      SAP HANA is a high-performance in-memory database and platform by SAP. It facilitates real-time analytics by connecting systems, extracting data, and enabling seamless data loading.

      OvalEdge provides an interface that can connect to SAP HANA and perform all standard operations. The SAP HANA data source is integrated via the JDBC driver that supports crawling database objects, profiling sample data, query execution, and building lineage.

      Connector Settings 

      Once the connection is validated successfully, various settings are provided to retrieve and display the information from the data source.  The connection settings include Crawler, Profiler, Query Policies, Access Instruction, Business Glossary Settings, and Others.

      Connection Settings

      Description

      Crawler

      Crawler settings are configured to connect to a data source and collect and catalog all the data elements in the form of metadata. 

      Profiler

      Profiling is the process of gathering statistics and informative summaries about the connected data source(s). Statistics can help assess the data source's quality before using it in an analysis. Profiling is always optional; crawling can be run without profiling.

      Query Policies

      The Query Policies in the Crawler setting provide the right access to the Query sheet functions (Join, Union, SUM, or aggregate functions). You can specify the desired roles and permission to deny the usage of the query sheet function. A role that has been denied policy permission will not have access to those functions in the Query Sheet.

      Example: If the user selects the Role as “OE_HRADMIN,” Query Type as “JOIN,” and the Access Type as “DENY,” then the users associated with the OE_HRADMIN privileges are restricted from using the JOIN function in the Query Sheet page.

      Access Instruction 

      It allows the data owner to instruct others on using the objects in the application. 

      Business Glossary Settings

      The Business Glossary setting provides flexibility and control over how they view and manage term association within the context of a business glossary at the connector level. 

      Notification

      The Enable/Disable Metadata Changes Notifications option is used to set the change notification about the metadata changes of the data objects.

      • You can use the toggle button to set the Default Governance Roles (Steward, Owner Custodian, etc.) 
      • From the drop-down menu, you can select the role and team to receive the notification of metadata changes.


      For more information, refer to the Connector Settings.

      The Crawling of Schema(s)

      You can use the Crawl/Profile option, which allows you to select the specific schemas that need to be crawled, profiled, or unprofiled. For any scheduled crawlers and profilers, the defined run date and time are displayed to set.

      1. Navigate to the Connectors page, and click Crawl/Profile. 
      2. It allows the user to select the specific schemas that need to be crawled, profiled, unprofiled, or scheduled.  
      3. Click on the Run that gathers all metadata from the connected source into the OvalEdge Data Catalog. 

      Note: For more information on Scheduling, refer to Scheduling Connector
