The Logical Framework Approach takes the form of a four-by-four project table, often referred to as a "Logframe". The rows represent types of events that take place as a project is implemented: Activities , Outputs , Purpose and Goal (from bottom to top on the left hand side — see EC web site under external links).

The four views of the model are logical, development, process, and physical view. In addition, selected use cases or scenarios are used to illustrate the architecture serving as the 'plus one' view. Hence, the model contains 4+1 views: [1] Logical view: The logical view is concerned with the functionality that the system provides to end-users.

The 64-bit variant runs on CPUs compatible with the 8th generation of x86 (known as x86-64, or x64) or newer, and can run 32-bit and 64-bit programs. 32-bit programs and operating system are restricted to supporting only 4 gigabytes of memory, while 64-bit systems can theoretically support 2048 gigabytes of memory.
Logical Data Modelling The process of identifying, modelling and documenting the data requirements of the system being designed. The result is a data model containing entities (things about which a business needs to record information), attributes (facts about the entities) and relationships (associations between the entities).
The first logical framework was Automath; however, the name of the idea comes from the more widely known Edinburgh Logical Framework, LF. Several more recent proof tools like Isabelle are based on this idea. [1] Unlike a direct embedding, the logical framework approach allows many logics to be embedded in the same type system. [3]
