Introduction to cubes and dimensions
What tables are to relational databases in the way cubes are to TM1. Almost all data stored in TM1 is stored in and accessed from cubes.
There are two ways to create cubes:
- Empty cube: You can create an empty cube by selecting (at least) two dimensions from the list of existing dimensions in the Creating Cube window to create a new cube with no data.
- External data sources: You can create a cube and load it with data by using TurboIntegrator to identify and map dimensions and data from an external data source to a new or existing cube (of course, this requires some expertise using TurboIntegrator).
Each and every TM1 cube must have at least two dimensions and a maximum of 256 dimensions.
Without dimensions, there will be no cubes. So let's start the discussion with dimensions!
