Web Aplication Explanation

What is web page ?
I learnt this subject on replacement class, my lecturer gave us 3 weeks that our class left behind with other class. Web Page is a document containing text and graphics created with HTML that is part of group of hypertext documents or resources that can be accessed through internet. There are two types of web pages; static web page and dynamics web page.

And what is differences between them ??
Web statics is web that the content we only read the information that webmaster give, and we cannot give the comment or opinion inside those web page. Is mean we cannot interact with one another (reader and webmaster), also this type we called web page 1,0. E.g AIU website (
Web dynamics is web that the content we can read and give comment. And we can interact with the owner of the web. We can give the comment if the contents are false or u can give suggestion. We called web page 2,0. E.g, and so on.

IS Develoment Methodology

IS Development Methodology is collection of procedure, techniques, tools, and documentation aids which will help the systems developers in their efforts to implement new IS. If we want to build a new software or an information we must refer to that particular methodology to make analysis and design process more accessible to non-expert. ISD methodologies is recommended of philosophies, phases, procedures, rules, technique for developers of information systems. There are many types of ISD methodologies to build Information Systems :

·         STRADIS
This method is introduced by Chris Gane and Trish Sarson on system analysis and design in the 1970’s. their method based on logical model, using graphical techniques to enable users. Also this method focus on flow diagram which is used to describe process in the system and how to transform data.

IE is an architectural approach to planning, analyzing, designing, and implementing application within an enterprise.

JSD is is a method of system development that covers the software life cycle either directly or, by providing a framework into which more specialized techniques can fit.

An easily modified and extensible model (representation, simulation or demonstration) of a planned software system, likely including its interface and input/output functionality.

·         SDLC (System Development Life Cycle)
The oldest and most known methodology used to coordinate the efforts of information systems development is known as the “Waterfall”. The model is based on a set of generic life cycle stages to guide developers from an initiating through maintenance of the completed systems.

Type of IS

1.     TPS (Transaction Processing System).
The transaction processing system records the data from everyday operations throughout every division or department in the organization. Each division or department is tied together through the TPS to provide useful information to management levels throughout the company. It used by Supervisior (lower/operational manager) to monitor operational everyday.

2.     MIS (Management Information System).
MIS is an integrated collection of people, procedures, databases and devices that provides managers and decision makers with information to help achieve organizational goals. The function of MIS is to help an organization achieve its goal by proving manager with information. MIS take the data and make decision to get reports (output) like summary, demand, periodic. It used by middle manager (tactical Decision).

3.     DSS (Decision Support System).
An organized collection of people, procedures, software, databases and devices used to support problem-specific decision making. It is used for complex "what-if" questions that require internal and external data. Decisions at this management level are mostly complex. Same like MIS, DSS systems are used by middle manager (tactical) to solve specific problems in organization.

4.     ESS (Expert Support System).
An Executive Support System (ESS) is software that allows users to transform enterprise data into quickly accessible and executive-level reports, such as those used by billing, accounting and staffing departments. An ESS enhances decision making for executives.
Sharing the same concepts of a DSS, an ESS focuses more in the end-user requirements of maximum interactivity and user-friendlyness. An ESS can be understood as a friendly, fully customised and interactive DSS to be mostly used by top executives and policy-makers to get permanent and updated assessment in relation to key questions (information and knowledge).

While a complete DSS will have efficient links to  external large   databases and advanced  models, an ESS focuses only on interactive and executive assessment tools, those which can be used personally by end-users. An ESS requires a previous expert work filtering information and knowledge into meaningful indicators and tools.

In this topic also we had Assignment about Information System in AIU Library :

Information System

What is System ?? System is a se of elements or components that working together to achieve a common set of objectives. So, information system is A Set of interrelated elements/components that collect , manipulate , store, disseminate data and information.

The picture above shown that the component of Information System, such us; people, telecommunication, Software, Hardware, Database, and procedure. The component are used to build any kind of services; e.g PayrollSytem, customer services, Inventory System, Marketing System.
·         People.
People who manage, run, program, maintain the system work properly. People also the important thing that Information System must be included.

  • ·         Telecommunication.

Telecommunication is electronic transmission of signal for communication which is enable organizations to carry out their process and task throught effective computer; for example Information System need Internet connection.

  • ·         Software.

Consist of computer programme that govern the operation of the computer. E.g finance software (process payroll, send bills to customers, provides manager with Information System)

  • ·         Hardware.

Consist of equipment used to perform input, processing and output activities.

  1. ·         Database.

Database used for organizing collection of facts and information, typically consisting of two or more related data files.

  • ·         Procedure.

Procedure is strategies, policies, methoes and rules for using computer information System including operation, security and maintenance of the computer.

ICT in Daily Life

In 21st Century, ICT make influence in our society. Such us our healthy, business, government, education, and science. In this lesson, we had presentation assignment about ICT in our daily society. We divided by 5 group and each group, my group were yusuf from Singapore, firdaus from Malaysia, Zulkarnain from Indonesia and Adnan from Kosova; our topic was ICT application in government. We have chosen Singapore because in Singapore the government success leading the country and use ICT in their system.
Our Group Presentation

There are several application that Singapore use :
·        Housing.
This application for count people that people live in Singapore. Its make government easier to count, because they use this application. And also make singaporian easier to find new house consider with safety and cheaper.

·        Health.
In health application, the Singaporian can access information about health online. Also the government will post the article about health, new viruses, how to avoid the disease and so on. This application is helpful.

·        E-Government.
E-Government consist of portal web, online news, security (streaming CCTV), national service. Government make this application to catch people to get information from any media; handphone and computer devices.
Also in this portal government can introduce tourist area, hotel, transportation, employment

·        Smart Card Alliance.
Smart Card Alliance is the company that provide electric payment. We don’t need to bring more money, but our money is inside the card. And we just scrabe the card into the machine. It usually use for train, bus and any kind of payment.
Smart Card

Information Technology

Information Technologi (IT) is Any computer-based tool that people used to work with information and to support the information and information-processing needs of an organisation. And IT can be divided into 2:

  • Information Technology Architecture
A comprehensive view of an IT Architecture specifies policies and principles that indicate direction, and services and common solutions, standards and guidelines, and products that detail the means of implementation.
The framework for the IT Architecture is that of a cube sliced into five sections or layers from back to front. Each section or layer represents a type of architectural specification from the most general IT policy layer at the back of the cube to the most specific product layer at the front of the cube.

  1. ·        Information Technology Infrastructure

While IT Strategy determines what your information technology must accomplish in order to achieve your business objectives, it is the IT infrastructure that has the supporting role; because its capacity, reliability, and level of vulnerability directly impact your ability to implement successfully and ultimately reach objectives.
IT infrastructure and its ability to meet the needs of their businesses. We do not sell hardware or software. We assess what’s available based on your needs, priorities, and budgets; and then we make recommendations according to what our experience suggests is the best fit for your organization. Although we do work with and will refer reputable vendors, we are never involved in that revenue stream ensuring that our sole intent is finding the best possible solution for you.
When it comes to infrastructure, we can help you identify the right combination of components for your business based on a range of criteria including; budget, scale, capacity, availability, level of security, IT operational procedures, redundancy requirements, staff competency, partners involved, etc. Our analysis will typically include higher and lower end alternatives to provide a range of options for your consideration so that you can be sure of selecting the best possible cost/benefit combination.
