There are two types of account-based models:
- Classic account model
- New model
Accounts-based models have a single measure with multiple accounts. Measures are the structures in your model that hold numeric values.

In a classic account or new model, model values are stored in a single default measure, and you use the account structure to add calculations, specify units, set up an account hierarchy, and set aggregation types for all the data. For example, financial data is broken down by general ledger account (i.e., discounts and gross sales), which is used to describe the values in the measure column (i.e., signed data), which represents transaction data.
