In SAP Analytics Cloud, dimensions represent master data in general. For example, product, cost center, and employee are all examples of dimensions. A model can have any number of dimensions.
On the other hand, a Measure represents transactional data (quantitative). In a classic account model, model values are stored in a single default measure, and you use the account structure to add calculations, specify units, and set aggregation types for all the data. In the new model type, you can add and configure multiple measures with aggregation and units to fit your data.
Dimensions can be private (model specific) or public (shareable across models).
