CobiT definition:

The information systems function creates and regularly updates a business information model and defines the appropriate systems
to optimise the use of this information. This encompasses the development of a corporate data dictionary with the organisation’s
data syntax rules, data classification scheme and security levels. This process improves the quality of management decision making
by making sure that reliable and secure information is provided, and it enables rationalising information systems resources to
appropriately match business strategies. This IT process is also needed to increase accountability for the integrity and security of
data and to enhance the effectiveness and control of sharing information across applications and entities.
