Logical Data Model
A Logical Data Model fills in the gap between a Conceptual Data Model and Physical Data Model. While Conceptual Data Models are completely devoid of database-level information, a Logical Data Model stores generic characteristics (such as indexes and foreign keys) without adding anything specific to a single DBMS. Physical Data Models translate information from a Logical Data Model to designs that are specific to a certain DBMS.
Loosely Coupled
A flexible architectural approach to the connection between two or more computer systems that are exchanging data. Loosely Coupled systems are considered useful when either the source or the destination computer systems are subject to frequent changes. This is in contrast to tightly-coupled connections, which are less flexible and more difficult to change.
