Workspaces are the data storage units of Mantid. If you want to create, save or manipulate in any way a workspace this is done using Mantid Algorithms.
For example an algorithm is used when loading data into a workspace. The current list of available algorithms is very large, but most algorithms interact with workspaces in the same way, outputting a new workspace as the result.
In this section we will introduce you to some basic types of workspaces, and some key algorithms to operate upon those workspaces.
