Using the delivery service example above, the Warehouse Management system should get access to only a subset of the customer data for security reasons. And it shouldn't get any level of access to the Credit Card Processing system. This level of access is called defined by the Access Control Lists or "ACLs". Data Governance is used to describe managing the ACLs. Data Governance also defines where the data records are stored.

Several terms have been introduced and it may be helpful to review them before moving on:
- Data Integration (DI) The process of transforming and transferring data from one system to anotherAccess Control Lists (ACLs) The defined access limit to MDM data records for any given system, application, or role.
- Adaptor Applications, modules, or some software or hardware component that transforms data from one format to another so that the data can be consumed by another system.Data Governance Managing data access, i.e. who accesses certain data sets based on role, application, etc. Defining where the Master Data is stored.
- Data Domain (Domain) A set of fields or properties that define a set of data (i.e. the "Customer" data is comprised of the name, address, and phone number properties).
- Data Governance Managing data access (i.e. who accesses certain data sets based on role, application, etc. defining where the Master Data Management (MDM) An approach to reducing data redundancy across systems by maintaining a master file for critical dataData is stored).
- Data Integration (DI) The process of transforming and transferring data from one system to another.
- Data Record The latest (most recent) version of a given record.
- Federated MDM Whereby the latest change to a record is noted in one of the organization's systems without actually storing the data in YOUnite (in the YOUnite MDM data store).
- Master Data (MD) The master or golden version of a record (for a customer, for example). The "record of truth."
- Master Data Management (MDM) An approach to reducing data redundancy across systems by maintaining a master file for critical data.
- YOUnite Data Store Whereby the latest change to a record is saved inside of YOUnite (in the YOUnite MDM domain).
- Federated MDM Whereby the latest change to a record is noted in one of the organization's systems without actually storing the data in YOUnite (in the YOUnite MDM data store).
- Acess Control Lists (ACLs) The defined access limit to MDM data records for any given system, application, or role.
