Introducing the Data Catalog¶

The default URL for accessing the Denodo Data Catalog from a local machine is http://localhost:9090/denodo-data-catalog. Type it in your favorite browser and you will see the login page.

Login page of the Data Catalog¶

In the data infrastructure of your company you may have several Virtual DataPort servers, each one with a different catalog to discover. Select the Virtual DataPort server you want to connect to and sign in with your credentials. The Data Catalog will welcome you with its new home page.

Home page of the Data Catalog¶

From the home page of the Data Catalog you can start discovering new data resources of your organization. Just enter a query in the search bar to find views, web services and external elements by their metadata (name, description, fields…). You can also browse your data resources by category, tag, or database/folder using the links below the search bar.

To help you discover new elements among the data resources of your company, the home page presents you with a selection of items organized by different topics:

Browse The Catalog: This section shows the number of items of each type managed by the Data Catalog.

Popular Assets: This section highlights frequently used and recently updated data resources.

• Most used lists the views and web services most requested by all the people in your company.

• Recently added shows you which elements are new in the catalog.

• Recently endorsed is the list of views and web services that have recently received an endorsement from someone in your company.

For You: This section personalizes recommendations based on your activity:

• Recommended by Denodo Assistant shows you a ranking of elements from the catalog that can be of your interest according to your interactions with the Data Catalog and the Virtual DataPort.
