Information is the knowledge of something and its specific description. Some examples of information are the facts of history, maps, etc. Information, in a broad sense, is structured, processed and organised information. It provides context to other data and helps decision making. For instance, a person’s sale in a restaurant is financial data-it becomes financial information when the company is able to identify which food is the most profitable or least profitable.

Organizations require large amounts of information systems and computing resources to support their needs. Organizations are adopting information technology because it increases processing power, lowers the costs of data entry and improves information accessibility. Organizations using information technology are able to process large volumes of data quickly and efficiently. Organizations using information technology are able to make better decisions than their counterparts using manual systems or operating systems.

Data warehousing, information systems, and database management software are the key components of information technology. Web application development environment is an important part of developing information technology. The web application development environment includes web page creation, web server configuration, graphic user interface (GUI), image manipulation applications, image gallery browser, etc. The organization developing the web application needs to decide how to use the database management software.

Database management software is part of information technology. The computer systems used for database management are generally SQL, Oracle, MS-SQL, MySQL, and Oracle. The database management software is designed to store and retrieve data that can be retrieved through a web browser. The application includes language support for programming languages such as HTML, XML, PHP, etc., dynamic content management systems, stored procedures, and application programming interfaces (API).

Information in informational equivalent is stored and retrieved in two ways: spatially and functionally. Spatially, information is changed and updated in accordance with a subject’s needs or objectives. The information is retrieved through a cognitive process which includes categorization, synthesis, deduction, and reasoning.

On the other hand, information is retrieved and used by a physical information environment, which is an information system that operates and executes on a CPU. Information processing and storage of information usually consists of logical processes such as processing, storing, and retrieval. Information systems developers play a major role in the operational support of the organizations in which they work.

The information systems developer designs the physical information environment. For instance, the Web has servers, client-server technologies, and file formats. Each of these technologies has their own architecture. A server can be divided into operating system kernels, controlling software, and application software. Client-server technologies include programming language, hypertext transport, and database management systems. These technologies provide information to computers, operating systems, storage devices, and other software applications through a server.

An information systems developer thus plays a critical role in the maintenance of information systems. This ensures smooth operation and effective usage of information technology. Thus, this field is highly specialized and demands a great deal of training, skills, and experience.
