# About Data manager
{: #exp_objects}

The **Data manager** page in IBM® watsonx.data is the entry point to browse the schemas and tables by engine. You can select an engine by selecting the **Browse data** tab to view the associated catalogs, schemas, and tables.
{: shortdesc}

From the **Data manager** page, you can create schemas and tables by using the **Create** option. You can also select a catalog or schema, click the overflow menu, and use the corresponding **Create** option to create a schema or table. **Create table from file** option in the overflow menu of schema is also used to ingest a data file into watsonx.data. Similarly, schemas and tables can be dropped from the catalogs.

Wait for a few minutes to view the changes after a schema or table is dropped.
{: note}

You can **Ingest data** from the **Data manager** page.
Other tasks that can be performed in the **Data manager** page include adding, renaming, or dropping a column.

You can browse the **Table schema** and up to 25 rows of **Data sample** for some tables. You can view the **Time travel** snapshots and use the **Rollback to snapshot** feature to rollback or rollforward to any snapshots for Iceberg tables.

watsonx.data provides pre-defined **Sample and benchmarking data**, such as **tpch** and **tpcds**, to test the performance of a database system under controlled conditions. It also provides **System monitoring data** that uses **jmx** and **system** metrics to collect data about the system's health and performance during benchmark testing to understand how the system responds to the workload. **Sample and benchmarking data**, **tpch** and **tpcds** can only be queried using the Presto engines.
