3rd topic

  Information System

           In this trimester as a last lesson which was related to information (IS) and the system methodology. During this week our lovely miss taught us about the (IS) which we are familiar as an information system, and she described a short detail based on this topic. Based on my understanding, what I have learned the definition of the information system is the set of components or elements, which works on the base of it's module. In information system we have to follow the IS module which is start from input and processing to create output by using information system.

       After having finished this part she also described us about (CBIS). Which is a combination of software, hardware, telecommunication networks that people build and use to collect, create, distribute data or information in an organization. Furthermore, that is the software based solution used together and analyse the information. She also explained us about different types of (CBIS), which we use in an organization to develop new technology. Afterwards, she focused on the common usage of (CBIS) in organization and in business. In organization business, people and information are inter related. In the business strategy, we use three types of information such as strategic, tactical and operational. These types of information in business organization used by people, worker and end user.

                                                             
     After giving the short summary our beloved lecturer has described us about the components of CBIS such as hardware, software, database, telecommunication network as well people and so on. Afterwards she gave us concise idea based on the components of CBIS and their uses in information system. She has also shown us the difference among software, hardware and their components. From my understanding software is an intangible part of computer but hardware allowed user to enter data into the information system. The the following one is database which is organised collection of interrelated data. It is the place to store data. The next is telecommunication which means to all communication media. As a last one is people means the person who manage , run the programme and maintain the data. On the other hand, people are also include in components of IS. They also can be IT architecture, system analyst or designer.

                                                             
     Times was going so fast, but we are still in the same topic. So, to continue our topic in the next class our sweet and lovely lecturer taught us about the development information system methodology which is the under topic of information system. To check our understanding our lecturer asked us some question from the previous part before continuing our class. Then she continue the class by the system development which is the process of defining, designing  testing, implementing new software application or programme and so on. There are seven kinds of information system development methodology exists in the tecnological word between them three methodology are most important such as SDLC, PROTOTYPING and STRADIS. We also can define the system methodology which is all about a conceptional model used in project management and also describe all the stages that used in information system management. There are six participants in system methodology such as project manager, stockholder, users, programmer, system analyst as well support personnel which method also follow the six stage to work on it.
