# Map Chains
Accessed through clicking Development > "**Map Chains"** link on the left side panel of the application.
Map Chains are a series of mappings that are linked together to form a complex data integration process. Map Chains are used to automate the transfer of data between multiple systems and applications, and to transform and manipulate the data in a specific order. By using Map Chains, this reduces the time and effort required to perform manual data mapping and manipulation, and improves accuracy and consistency of the data integration operations.
On the top of the Mapper panel there are controls for:
* Creating a new Map Chain
* Opening a Map Chain
* Save a Map Chain process
* Run the Map Chain process
