ANALYSIS SYSTEM

1. Definition of Systems Analysis

Systems analysis is a term that collectively describes the early phases of system development. Systems analysis is a technique that describes the problem solving component parts by studying how well the component parts work and interact to achieve their goals.



2. Definition of System Design



A problem-solving techniques which are complementary to a string back into the component parts of a complete system which he hoped. An improved system. This involves additions, deletions and changes to the system relatively early parts.



3. Information Systems Analysis



Development phases in the development of information systems that mainly focused on the problems and requirements of business, independent of any technology that can or will be used to implement solutions to those problems.



4. Model analysis approaches Driven



Model Driven is analysis that uses images to combine the issues, requirements, business solutions. Examples of model is frequently used flowchart and DFD. example of the analysis is driven by pendekatanmodel:

Object-oriented analysis



4.1 Structured Analysis



First is one of the first formal approach for the analysis of information systems. This analysis focuses on data flow and business processes and software. This analysis process is called oriented. Analysis of data flow diagrams (data flow diagram) depicting the process of existing or proposed, together with the input, output and file them.



4.2 Engineering information and data modeling



Engineering duluterfokus information on the structure of data stored on a system. So say centered data. Data models in engineering is called entity relationship information. For more details would be discussed at the next module. Engineering information is said to center on the data because the emphasis on learning and analysis requirements
