# Region Properties Panel

In this article, we will explore and discuss the various properties of data regions in a report model. But first, let us explore what a data region is.

## What is a Data Region?

A Data Region is an area of data captured within your report. It can cover any number of lines in a source report. This area is defined by specifying a pattern.

Setting up a data region is one of the first steps of extracting data from a report. Data regions are the backbones of Report Models – they direct Astera where to extract data from.

To support the selection of data regions, Astera contains a set of Region Properties.

* *Line Count*: Ends your region after a specified number of lines.
* *Blank Line*: Ends your region where a blank line occurs.
* *Last Field Ends*: Ends your region at the last data field within your data region.
* *Another Region Starts (100 Rows Max)*: Ends your first data region where the next data region begins. This is used for variable-length data regions.
* *Till Regular Expression*: Ends your region when the specified regular expression occurs.
* *Till Specific Text*: Ends your region when the specific text string occurs.

*Line Count:* Allows the user to vary the line count according to the requirement of the data region.

**Note:** The *Line Count* option appears dynamically, depending on which option is selected from the dropdown menu of *Region End Type*.

*Overlapping Container:* Used when there are multiple data regions with overlapping lines.

*Container Region:* Used when a data region contains a sub-region within its boundaries.

This is how you can define and modify Region Properties in a report model.
