Web Information System (WIS)

In this week I just learnt about web information system. WIS is web-based information system, is an information system that uses Internet web technologies to deliver information and services, to users or other information systems/applications. It is a software system whose main purpose is to publish and maintain data by using hypertext-based principles.

A web information system usually consists of one or more web applications, specific functionality-oriented components, together with information components and other non-web components. Web browser is typically used as front-end whereas database as back-end.

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 (www.aiu.edu.my).

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 blogger.com, wordpress.com 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.

·         INFORMATION ENGINEERING

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

·         JACKSON SYSTEM DEVELOPMENT

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.

·         PROTOTYPING

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 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.
