The persons who work for the company are known as data workers. The best example for data workers are employees. The information system types comes under this department are Knowledge management system (KMS) and Office automation system (OAS). In any organisation KMS is used to capture, organise and create business processes in efficient and innovative way. To get the right information we collect data and apply knowledge. The organisation success depends upon the knowledge. All the employees in an organisation must share their thoughts for the organisation goal. The professional people who works for the KMS acts as advisors and give assistance for both Top level and Middle level management. These People develop new knowledge for the organisation and integrated it with existing knowledge which is nothing but updating the system. Example for KMS is the banks say that deposit money in banks for protection. In addition to that the knowledge they use to increase the customers is if you deposit the money for more than a year we will give an additional 5% for the money which means if you deposit $100 then at the end of the year you own $105. OAS is an additional tool to make the process easy in the organisation. A computer system which allows variety of application such as Microsoft word, Emails, Calender and even sharing resources each other through a connected network. This is used mainly by office workers who supports managers at all levels. The best example for OAS is Microsoft word. This application is of user interface which helps to make the documents more easy and has additional facilities like spell correction, word count etc.
This is one of the department/layer in an organisation. The major role is to monitor subordinates like data workers, operational manager before reporting to upper manager. The Information system types that involve in this department are Management Information System (MIS), Decision Support System (DSS), and Intelligent Support System (ISS). Manage information tells manager how to manage information for a particular situation. This information is managed in accurate, timely and relevant for situations. System is a combination of different levels in an organisation. MIS is defined as combination of different layers in organisation, people and documents to know the organisation problems and provide appropriate information for the problem. Accessing, Organising, Summarizing and displayed information for supporting routine decision making in the functional areas. The four types of MIS are TPS, OIS, DCS and Expert Systems. The example for MIS is for an online bank bill payment, the account holder has an option to transfer the amount for a particular date in each month. The bank transfers money each month on that date and send a email with information about how much money is detected, time of transfer and date of transfer. DSS is a system used to make decision with the help of wide range of resources. This system interacts with the people by using range of resources to make decisions which we see in organisation. For example, company wants to sell books internationally through online. To do this the company need to think wether the decision made is wise for business. Company can use DSS for making decisions with the help of company information and also by other resources. This result gives an idea for the company to expand the business internationally or not.
