Week 9……………… Google sites



In the early Friday morning we were gathering at AIU library on the third floor with our lecturer. When everybody sat down our lecturer started to begin the class. Usually she started with Assalamualaikum and very good morning to everyone and also recites Al-fatihah. This is a very good way to begin the class. For today I felt something unusual because this time the environment was not like in class as there was no whiteboard or projector. It is something like we were going to have a conference. Suddenly our lecturer asked everyone to find a group which is must not same member with the previous one and one group must have three members. First I thought we are going to play some game but it is not actually. For this time we were given new project about creating Web sites with Google sites. So our lecturer gave us guides study how to create the web sites. I felt quite lazy in the first time when I heard the news. Anyway I have to do it finally and if I think positively I will get benefit from it. So for my group we decided to create the Web site about AIU pencaksilatclub and we will do our best to create it. For who interested AIU penccaksilatclub you can visit our Web sites as the link below:
https://sites.google.com/site/aiupencaksilatclub/home
 


Ok that’s all for this week …Do not forget to visit the Web sites you are welcome….bye

Week 8



Now I have already past haft of this semester the time is flying meanwhile, I am walking. Normally I sleep at night and get up in the morning this is how is the life going on. So what the point of living is to get the better day than yesterday. Anyway when I look back to myself I always asking myself that am I doing my best to day?.
So in this week as I said at the last post our class has some problem so we cannot use it. In this we moved to G8 class in foundation building. So this week I was late coming class again. It was embarrass when everybody was looking at me so I just smile to all my friends and say good morning.
          When everybody was in the class our lecturer started to teach us as usual. She didn’t teach us as usual to day she gave us some task to do by group. We were given a case study where we had to select the most appropriate IS methodologies for developing any information system in AIU for student registration and hostel registration as well as preparation of exam results and present it to the higher authorities of AIU. It was terrible for me because I did not do a research. So I had no idea the first time but fortunately it was grouping work. So helped together and finally I finished it in a time.
          For my group we chose Jackson Methodology. Why we choose this this one. Let’s we see how is it and why we chose it.
Jackson Methodology is the suitable methodology for AIU. There are three basic principles for Jackson Methodology:
         Development must start with describing and modeling the real world, rather than specifying or structuring the function performed by the system.
         An adequate model of a time-ordered world must itself be time-ordered. Main aim is to map progress in the real world on progress in the system that models it.
         The way of implementing the system is based on transformation of specification into efficient set of processes.
Why?
The JSP steps in developing a program are:
        Draw a data structure for each input and output file.
        Draw a single program structure that contains program components to handle correspondences between the input and output data structures. For example: "Consume input files record; write output report line"
        Complete the program structure by adding program components to handle input and output data components that have no counterparts in other structures. For example: "Write report file summary line"
        List the operations needed by the program.
        Allocate each operation to the appropriate component of the program structure. Note that certain operations (READ operations, for example) may be allocated multiple times, to several different components of the program structure.
        Specify the conditions for iteration and selection.
        Translate the whole thing into code
 So that all for this week ……………see you then.


Week 7 different information system methodology




After had a nice holiday last week which was very nice and extremely relaxed at my hometown in Thailand. I came back to AIU on Saturday night. This week was one of the very busy weeks in this semester as I have many assignments to complete. Especially ICT group project which we had to submit in week 7. So everything were went well my group have done the project and submitted it in the class on Friday.
 This week we continued our lesson about different information system methodology. Unfortunately air-con and all electricity were not working. The class was very temperature and we could not use projector. So our lecturer decided to send us off to library to do a research. She gave us five types of information system methodology. They are
1) STRADIS ( Structured Analysis, design and implementation information system)
2) Jackson
3) SDLC (System Development Life Cycle)
4) IE (Information Engineering)
5) Prototyping
So we have to search about them we did it by group actually. And in the next class we will discuss about that. So as i said we didn't study in this week we just submit our lesson and went to library because of the electricity problem. I think  that all for this week which is week 7 so see me again next week…………………………………………bye,,,,,thank you 


Week 6.... type of Information system



In this week we continuous to learn about type of Information system as in the week we learned about what is information system and its components.
Five Types of Information Systems. Information systems are constantly changing and evolving as technology continues to grow. Formation systems can generally be classified as follows:
1. Transaction Processing System (TPS)
Applications of information systems that process business transaction data. Its use at operational level and focuses on the data. An example is a computer application for typing.
2. Management Information System (MIS)
Applications of information system that aims to provide information used in the field of management (management-oriented reporting.) Examples are computer applications for hospital services, pharmacy purchasing, scheduling of production machinery and others.
3. Decision Support System (DSS)
Applications of information systems that provide decision-oriented information and especially in situations where decision-making. At the executive level often called Executive Information System. For example a computer application to determine the purchase of drug stocks at the hospital, the determination of sugar distribution system and others.
4. Expert System (ES)
Information system designed to produce a decision by reproducing knowledge and expertise of the decision maker and problem solver and then simulate it. For example advanced applications of artificial neural networks, face recognition and so forth.
5. Office Automation System
Systems that support business activities on a large scale. Examples ERP applications for the company.



week 5.........................


This week I had class on Friday morning as usual but at the last night before that day I didn’t sleep well so I got up late and went to the class late. When I reached at the class I noticed sometime strange because nobody in the class then I suddenly called to my friend to ask what happened. So he answered me that we got a quiz to day and we changed the class to G2 in foundation building. So I quickly went there I was very afraid that how to tell the reason why I was late. But fortunately at that day my lecturer didn’t come she just asked to do the quiz after that we can go,,,,,,,,,,,,So at that day I  didn’t have any lesson and after I finished the quiz I went to my room for have a rest. This is a very confused week for me it was excited that I was late and excited that I do the quiz with very poor preparation. This my experience in the week I learnt that we must be ready for any test in every time so I have to do some review after I have learned. Those all for this week thank you.

week 4 information system


This week I learned about information system so now let begin with the definition of IS
Information system definition: An information system and MIS (IS) - or application landscape which is any combination of information technology and people's activities that support operations, management and decision making. In a very broad sense, the term information system is frequently used to refer to the interaction between people, processes, data and technology. In this sense, the term is used to refer not only to the information and communication technology (ICT) that an organization uses, but also to the way in which people interact with this technology in support of business processes.
The 5 components that must come together in order to produce a Computer-Based Information system are:
1. Hardware: The term hardware refers to machinery. This category includes the computer itself, which is often referred to as the central processing unit (CPU), and all of its support equipment’s. Among the support equipment’s are input and output devices, storage devices and communications devices.

2. Software: The term software refers to computer programs and the manuals (if any) that support them. Computer programs are machine-readable instructions that direct the circuitry within the hardware parts of the CBIS to function in ways that produce useful information from data. Programs are generally stored on some input / output medium, often a disk or tape.
3. Data: Data are facts that are used by programs to produce useful information. Like programs, data are generally stored in machine-readable form on disk or tape until the computer needs them.
4. Procedures: Procedures are the policies that govern the operation of a computer system. "Procedures are to people what software is to hardware" is a common analogy that is used to illustrate the role of procedures in a CBIS.
5. People: Every CBIS needs people if it is to be useful. Often the most over-looked element of the CBIS is the people, probably the component that most influence the success or failure of information systems.
that all for this week ,,and see you next week...thank you
