Without giving you a copied and difficult to understand web definition, it is basically any system supported by its entities that manages and changes information. Some common entities include people, software, hardware and the data itself. \n\nInformation systems can be big or small like those designed to manage groceries at your local supermarket or those designed to handle millions of transactions like the New York Stock Exchange. All of the entities involved in those systems help manage and move information. \n\nMy first source is some web defintions of IS while my second is some definitions for a wide range of technical terms.

A system of anything is a set of things that work together. A computer hardware system would be: a processor unit, connected to a monitor (screen) or more, plus printers, storage devices (disks), modems, and so on. So, I could ask: Is the system up, which means is the computer hardware system working. A system may also mean a software (program) system, a program that runs on the hardware system. So, a word processor (like Word) is an application system (actually an application system is a bigger system, so maybe MS Office is a system) that runs on the hardware system. So, I could ask: Is the system up? which means is the software running.

Information technology (IT) or Information and communication(s) technology (ICT) (also Infocomm, esp. in Asia) is a broad subject concerned with technology and other aspects of managing and processing information, especially in large organizations.\n\nIn particular, IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and retrieve information. For that reason, computer professionals are often called IT specialists, and the division of a company or university that deals with software technology is often called the IT department. Other names for the latter are information services (IS) or management information services (MIS), managed service providers (MSP).

Corporate information systems strategy \n\n•Describe the factors influencing an information system within an organization: management organization and functions, planning and decision making methods, general organization structure, responsibility for the information system within an organization, information flow, hardware and software, standard, behavioral factors e.g. personalities, motivation, ability to adapt to change. \nInformation flow \n\n•Describe the methods and mechanisms of information flow within an organization both formal and informal and the constraints imposed upon this by organizational structures... \n\nPersonnel \n\n•Understand the levels of task/personnel within an organization: strategic, implementation, operational and relate the needs of these three levels to the information system. \n\nSAMPLE\n\nIntro The business environment is very competitive. Consequently, COMPANY NAME needs to offer customers efficient and reliable service. If they do not, customers will switch to more consumer efficient companies. Furthermore, as our COMPANY NAME grows in size, it becomes harder to keep track of the growing amount of customer information. If COMPANY NAME does a poor job of organizing and maintaining customer records and data, it can result in problems for both COMPANY NAME and the consumer. \n\nII. Company Description \n\nIV. Solution\n\nVI. MIS Strengths and Weaknesses Before implementing the any new software and hardware we need to make sure under any new system all customer information and invoices can be quickly accessed by simply entering the number of the invoice, customer account or purchase order. Errors on invoices can be changed without having to retype the whole document. \n\nAny new system of software and hardware should allowed COMPANY NAME customer representatives to save time, which may be used in handling more complicated customer issues. Customer service has to be tremendously improved since customers seeking information on their transactions no longer have to be inconvenienced by waiting long hours. Instead, customer information should be available in real-time, at the moment the customer service representative needs it, a feat that could be made possible by On Demand software. \n\nThis means that as the COMPANY NAME accumulates data that eventually becomes obsolete or is rarely accessed, they can simply remove the cartridges that the information is stored on and replace it with a blank one. This allows additional storage capacity at a very low incremental cost. Furthermore, the use of a Database makes it possible to integrate information as web services. Without Database it would be very difficult to integrate all of the customer information to a web based form or make it accessible on the company's intranet. \n\nIn terms of weaknesses, it is hard to identify any limitations to COMPANY NAME management information systems.  It would seem that the Database is using the most advanced and reliable software and hardware available on the market, as is evidenced by the wide use of all of NAMED PRODUCT and services by companies around the world. \n\nVII. Competitive Advantage of Database MIS As previously stated, COMPANY NAME is involved in a wide range of markets and the range of products and services they provide is unparalleled by any other company. In short, there is no other company in the world that competes on the same level as COMPANY NAME. Rather, there appears to be several competitors in each sector or industry in which COMPANY NAME offers its products and services. Since their competitors are so much smaller, they don't require the same degree or level of information systems that COMPANY NAME has and it is therefore hard to make a comparison. What COMPANY NAME information system does for the company is allow it to be more flexible and swift than it was previously. Frequently, as companies grow, they tend to become more bureaucratic and less able to adapt to changes in the mark

Well your question is not clear.But if you wanna know what a database system is ...\nA database keeps all possible information in the form of records that are normally maintained in the form of tables.\nThere are some really advance techniques of handling these databases using Oracle or SQL server or DB2 etc.\nIf you want to do some basic operations you'll have to learn the language called SQL(Structured Query Language) which is language for the manipulation of databases.\nThese systems are normally the backend support for systems whose front ends are visible to you in the form various Web Applications,Web services and other Desktop based applications.

Management information system\n\n\nAs an area of study it is commonly referred to as information technology management. The study of information systems is usually a commerce and business administration discipline, and frequently involves software engineering, but also distinguishes itself by concentrating on the integration of computer systems with the aims of the organization. The area of study should not be confused with computer science which is more theoretical in nature and deals mainly with software creation, or computer engineering, which focuses more on the design of computer hardware.\n\nIn business, information systems support business processes and operations, decision-making, and competitive strategies.\n\nThe functional support role\nIt can also be called Data Base Management System wherein maximum utilization in an efficient manner based on the organisational needs is obtained by analyzing, processing and referenceing of Data Base. Not only for the business, but for all kinds of organisations such as Disaster Management Organisation for using it as Disaster Management Information System.\n\nBusiness processes and operations support function are the most basic. They involve collecting, recording, storing, and basic processing of data. Information systems support business processes and operations by:\n\nrecording and storing accounting records including sales data, purchase data, investment data, and payroll data. \nprocessing such records into financial statements such as income statements, balance sheets, ledgers, and management reports, etc. \nrecording and storing inventory data, work in process data, equipment repair and maintenance data, supply chain data, and other production/operations records \nprocessing these operations records into production schedules, production controllers, inventory systems, and production monitoring systems \nrecording and storing such human resource records as personnel data, salary data, and employment histories, \nprocessing these human resources records into employee expense reports, and performance based reports \nrecording and storing market data, customer profiles, customer purchase histories, marketing research data, advertising data, and other marketing records \nprocessing these marketing records into advertising elasticity reports, marketing plans, and sales activity reports \nrecording and storing business intelligence data, competitor analysis data, industry data, corporate objectives, and other strategic management records \nprocessing these strategic management records into industry trends reports, market share reports, mission statements, and portfolio models \nThe bottom line is that the information systems use all of the above to implement, control, and monitor plans, strategies, tactics, new products, new business models or new business ventures.\n\nThe decision support role\nThe business decision-making support function goes one step further. It becomes an integral part -- even a vital part -- of decision -making. It allows users to ask very powerful "What if…?" questions: What if we increase the price by 5%? What if we increase price by 10%? What if we decrease price by 5%? What if we increase price by 10% now, then decrease it by 5% in three months? It also allows users to deal with contingencies: If inflation increases by 5% (instead of 2% as we are assuming), then what do we do? What do we do if we are faced with a strike or a new competitive threat? An organization succeeds or fails based on the quality of its decisions. The enhanced ability to explore "what if" questions is central to analyzing the likely results of possible decisions and choosing those most likely to shape the future as desired. "Business decision-making support function" is a phrase likely to quicken the pulse of no one but an accountant, but, in fact, it is all about turning wonderful dreams into solid realities.\n\nTetova ...\n\nThe communication decisi
