MODM describes all necessary data for maintaining a complete overview over all financial transactions and positions as well as for complying with rules set by regulatory bodies, internal rules and instructions of the customers. The scope of data is chosen to achieve this purpose. Relying on the FIDM™-description of financial instruments, issuers and other institutions, MODM consists of the following sections ("packages" in UML-terminology):

Each class of the model is associated with one of the packages.
Each section of the model contains its own set of rules. However, some sections entirely deal with rules and preferences. The level of detail is chosen to comply with all requirements of front office, back office, reporting and accounting.
