CASE
- CASE tools provide a foundation to define, design, build, test, document and supporting information systems and software products.
- CASE tools provide a mechanism to evaluate the activity information at this time, defining the proposed changes, produce and validate the new information that focus on the changes, which will improve the performance and operations of the organization.
4 Reasons for Using CASE
- To improve productivity
- Facilitate communication between analysts and users
- To provide sustainability of the life cycle phase
- To test the impact of maintenance
CASE
- Uppercase tools (also called front-end CASE), usually do the design and analysis
- Lowercase tools (also called back-end CASE). This tool makes computer language source code from CASE design
- Integrated CASE tools (integrated CASE), making a good function of upper danlower CASE
- CASE repository is a database system where developers can save a developer of system models, detailed descriptions and specifications, and product development of information systems. Also called dictionary and encyclopedia.
- Forward engineering capabilities CASE tool that automatically create a model of the system software or database code.
- Reverse engineering CASE tool is the ability to read the program code from a database, application programs, and / or user interface and automatically akan mengenerate the equivalent system model
Upper-CASE
- Create and modify the design of the system
- Store data in the container (project repository)
- Container is a collection of recordings (records), elements, diagrams, screen (screens), reports, and other project information
- CASE tools this organization needs memodelkan da nmendefinisikan restriction system
Lower-CASE
• Lower CASE tools to create source code from CASE design computer.
• Source code can usually be made in several languages.
Diagraming Tools: used to draw a model system that is required or recommended in the system development methodology. Usually in the form of a model system can be connected with another model system to describe your in more detail.
Dictionary Tools: used to record, delete, edit, and print detailed specifications and documentation. Description can be associated with the form of a visible model of the system.
Design Tools: can be used to build system components such as input and output. Inputs and outputs can be dihubungan with the model system that has been dideskripsi.
Quality Management Tools: Analisamodel system, description and specification and design for completeness, consistency, and received confirmation for the rule of the methodology.
Documetation Tools: used to set up, manage, report on the model system, the specification and description, and create a prototype so that it can be reviewed by the system owner, system designer userm system, and system builder.

1. System Development Life Cycle
SDLC is a sisteminformasi development methods that have been used for several decades and is widely accepted in the structured approach to the analysis and design of modern information systems. SDLC seen as a process that skuensial (waterfall) with each step or fasanya have a definitive beginning and end point. However, in reality, SDLC is a process that iteratif (inkremental) where activities in one phase can be back to correct previous kefasa or filter the information that is contained.
SDLC is a schematic approach to solving business problems with every step or time have a unique activity. SDLC consists of some phase. There is a divided phase 6, phase 7 phase dan8. Although different in the number of steps, or fasanya, but they do not differ because it still remains in the 4-step process of SI, the Initiation system, system analysis, system design and system implementation.
- First phase (Identification-Inv)
This phase can also be referred to as the phase of identification or investigation. Business problem that appears due to the identification of the system needs a new or more modern or because there have been situations that provide opportunities for improvement and re-design of one or more of the existing system, or also the creation and integration of the existing system .
- Second phase (Analysis)
This phase is also called the analysis phase. This phase includes a study of the organization that includes the process, procedures, and the system applied by the organization. In the second phase is set for the initial needs of the new system, the logic of the system that have already developed, and the relationship between the various elements of the system and the data is also determined. In the end this phase will bring the proposal for the management of the solution to the problem that has been specifically defined and described the effect of the environment.
- Third phase (Logical Design)
Phase logic of this mode system that has been revised at this time and filtered to correct sources of problems identified and the business to determine the function that the new system proposed in accordance with the expected and meet the needs and objectivity, which is determined during the analysis phase. Made during the design phase is called the implementation of an independent, because he was not bound by the system software and hardwarenya.
- Fourth phase (Physical Design)
Model logic is converted into the last spesifikasifisik that includes
detailed specification of hardware, software, and programming intruksi necessary to change the system into a reality. Issues such as data capture, process and output the specific needs defined and developed in this phase.
- Fifth phase (Implementation)
In this phase programmer work, and up and install the physical model of the system that works. Akivitas in this phase includes the testing and final installation of the software and hardware. Finally, the phase in the implementation of this end-user akan ditraining to use the new system.
- Sixth phase (Evaluation)
Although the system has been comprehensively analyzed, designed, tested, installed, users sometimes find a problem with the new system is, or find something better to complete a task with the system. With this situation, then a necessary fasaya the maintenance phase to modify the new system for this purpose pengkoreksian a problem that is not found during final testing.

INFORMATION SYSTEM
SYSTEM
Hall and Fagen (1956): defines the system is a collection of elements that interact each other that a total of teintegrasi. City, cells, and the body is an example of the system. Likewise, automobiles, computers and washing machines are also a system. Formally, the system can be defined as a collection of elements of each other, with boundaries (Boundary), which can be identified, which work together to achieve a common goal.
From this definition can be seen that there are 3
important components of the system:
1.Elements of each other (interrelasi)
2.The existence of restrictions (Boundary)
3.The existence of a common goal
Inter-relations
Interrelasi concept suggests that the elements of the system is not sufficiently free (interdependen). In other words, if one element of a system failure or does not work, he will affect some or all the other elements of the system. These elements are often called subsystems, which work together to achieve the goal or object of the system.
Boundary
Boundary concept, the limit, suggests that the system can be defined within the context of all the systems and other limitations that can be defined by a virtual who have clear limits. Furthermore, the existence of the Boundary elements that cause the system should include, and the elements that are not included in the limits of the system that is meant a system is not part of the system.
Purpose
The third concept is the purpose of the public. Goal or purpose of a system is very easy, the reason is to be used. If the system does not have a reason not because he has a function or can not provide the functionality needed, the purpose of a system is not important, and the system is needed again.
Type System
System often associated with a closed system or a stable system mekanistik. Some systems rarely interact with the environment with the purpose or to receive input to output. As a consequence, the closed system tends to operate in without explaining assesses routine and high, and environmental changes do not tend to have a material effect on it. An example of this system is a closed terrarium. One of the important Characteristics of this system is that it can survive by itself (self-sustaining).
The system also often called open system or organic adaptive system. In this category, entities that are both Internally and externally is important. The system tends to be less open and less structured operational systems such as in closed. Furthermore, the Variations of interaction with other components and one with the environment, although probabalistik, constantly changing and less able diprediski from the closed system. Characteristics of any openly that he is able to adapt to changes in both internal and external. Although not perfect, two examples of a system for open interest is a systems Analyst oraganisasi business and information systems.
Information
Is that information? Information is a collection of the data that is processed / processed, which can be understood to be used in decision making. While the data itself is something that has not been organized and processed so it can not yet be understood. Data can be a fact of the accident.
