# Exploring your data[¶](https://doc.dataiku.com/dss/latest/explore/index.html#exploring-your-data "Permalink to this headline")

Once you have defined a dataset, the first thing that DSS allows you to do is to view your data in the “Explore” component.

Explore shows you a sample of your dataset. It also provides:

* Quick descriptive statistics, either on the sample on the entirety of the data

* Meanings, i.e. rich types. See Schemas, storage types and meanings for more information

* An overview of all columns

* The ability to sort and filter the sample

* The ability to choose which columns are displayed

All these abilities are also available while doing visual preparation of your data.

Note

For a step by step introduction to the exploration component of Data Science Studio, we recommend that you follow our Basic Courses. This section will focus on *advanced* and *reference* topics related to the exploration component.
