OdbcSqlServer
SQL Server ODBC Connector is a Relational Database Management system (RDBMS) that consists of a multithreaded SQL server. It supports different back ends, several different client programs and libraries, administrative tools, and a wide range of application programming interfaces.
In the OvalEdge application, ODBC Plugin (provided by OvalEdge along with the application) allows users to crawl and profile the datasets such as Tables, Columns, Views, Procedures, and Synonyms and helps build the data catalog and lineage.

Establish Environment Variables (Optional)
This section describes the settings or instructions that users should be aware of prior to establishing a connection. If your environments have been configured, skip this step.
Configure Environment Names
The Environment Names allow users to select the environment configured for the specific connector from the dropdown list in the Add Connector pop-up window. You might want to consider crawling the same schema in both stage and production environments for consistency. The typical environments for crawling are PROD, STG, or Temporary, and may also include QA or other environments. Additionally, crawling a temporary environment can be useful for schema comparisons, which can later be deleted, especially during application upgrade assistance.
Steps to Configure the Environment
Navigate to Administration | Configuration.
Select the Connector tab.
Find the Key name “connector.environment”.
Enter the desired environment values (PROD, STG) in the value column.
Click ✔ to save.

Connector Settings
Once the connection is established successfully, various settings are provided to fetch and analyze the information from the data source.
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
Profiler 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 also.
Data Access
Data Access (Data Access Authorization) is included in the crawler-specific connector settings to ensure that the right user is accessing the query sheet and queries in the data catalog. Here, the system validates the user credentials and allows that user to access the query sheet and queries in the data catalog.
It includes:
(i) OvalEdge follows OvalEdge data permissions (ii) OvalEdge follows Remote system permissions
Query Policies
It restricts the use of the selected query types based on your role.
Access Instruction
Access Instruction allows the data owner to instruct others on using the objects in the application.
Others
The Send 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.
