# Utilizing Data Profiler Navigator

*A license is required to access the Data Profiler on the DNAnexus Platform. For more information, please contact DNAnexus Sales (via* [*sales@dnanexus.com*](mailto:sales@dnanexus.com)*).*

## Overall about Navigation

Data Profiler helps you explore different levels of a dataset. There are 3 levels of a dataset in Data Profiler:

* Dataset level: Show cross-table statistics, relationships between tables, and summaries of all tables and columns in the dataset
* Table level: Show statistics of one particular table. It can also join with another table to create a joint profile.
* Column level: Show statistics of one particular column of a table. It can also combine with other columns in the same table to create a joint profile.

To navigate between these 3 levels, you can select from a navigator on the left side of the application. Once an option of the navigator is selected, the content of the main interface will change accordingly.

The user interface of Data Profiler consists of a navigator (left), which controls the content of the main section (right).

### Navigator

Navigator controls the content on the main section of Data Profiler. The main component of the Navigator is a hierarchical structure of the dataset.

The top level of the data hierarchy is Overview, indicating the dataset level. This level is selected by default.

Under Overview are individual tables in the dataset. Each table has a number on the far right indicating the number of columns in the table. You can click on a table to see all columns in it.

Above the Data Hierarchy, you can search for one or more columns. The Data Hierarchy will show tables that have at least one of the column names in the search list (OR logic).
