Behavior Diagrams Definition: Behavioral models describe the internal dynamic aspects of an information system that supports the business processes in an organization. During analysis‚ behavioral models describe what the internal logic of the processes is without specifying how the processes are to be implemented. Later‚ in the design and implementation phases‚ the detailed design of the operations contained in the object is fully specified. Use case diagrams are behavior diagrams used to describe

1.2. ACTIVITIES TIMING AND TOTAL FLOAT To determine timing of activities in the network diagram the following calculations were done for each node: Earliest Start-(ES)‚ Earliest Finish-(EF)‚ Latest Start-(LS) and Latest Finish-(LF). Field and Keller (1998‚ p. 191) ES and EF are found by using the forward pass through the network … from the unique project start node and ends at the unique project completion node. ES is the ending day for the previous node/activity‚ where more than one

Reading Response (Diagrams Matter by Stan Allen) “A diagram architecture is not necessary an architecture produced through diagrams.... Instead‚ diagram architecture is an architecture that behaves like a diagram‚ indifferent to the specific means of its realization." (Par. 13) This paragraph points out the answer that beginners architecture students struggled to find. In the process of design‚ I try to find the potential through the translation from reality to the abstract diagram. While I wonder

The Programming Development Life Cycle (PDLC) Programming can be defined as the development of a solution to an identified problem‚ and the setting up of a related series of instructions which‚ when directed through the computer hardware‚ will produce the desired results. The notification that there is a problem can come from a systems analyst‚ an end user‚ or management. The problem needs to be defined so that the correct solution to solve it can be a program. Once a program is written‚ it is

There are two phases involved in the design of any program: Problem Solving Phase Implementation Phase 1. In the problem-solving phase the following steps are carried out: Define the problem Outline the solution Develop the outline into an algorithm Test the algorithm for correctness Problem solving is a mental process and is part of the larger problem process that includes problem finding and problem shaping. (Problem finding means problem discovery. It is part of the larger problem

A Venn diagram is a drawing‚ in which circular areas represent groups of items usually sharing common properties. The drawing consists of two or more circles‚ each representing a specific group or set. This process of visualizing logical relationships was devised by John Venn (1834-1923). Each Venn diagram begins with a rectangle representing theuniversal set. Then each set of values in the problem is represented by a circle. Any values that belong to more than one set will be placed in
