Central Information System The goal of an MIS is to be able to correlate multiple data points in order to strategize ways to improve operations. Lack of security — the security of manual systems is implemented by restricting access to the file room. Experience shows unauthorized people can easily gain access to the filing room Duplication of data — most departments in an organization need to have access to the same data.
In a manual system, it is common to duplicate this data to make it easy to accessible to all authorized users. The challenge comes in when the same data needs to be updated Data inconsistency — due to the duplication of data, it is very common to update data in one file and not update the other files.
This leads to data inconsistency Lack of backups — if the file get lost or mishandled, the chances of recovering the data are almost zero. Computerized information system Computerized systems were developed to address the challenges of manual information systems.
The major difference between a manual and computerized information system is a computerized system uses a combination of software and hardware to record, store, analyze and retrieve information. Advantages and Disadvantages of a computerized information system MIS The following are some of the disadvantages of a computerized information system.
Advantages: The following are the advantages of computerized information systems Fast data processing and information retrieval — this is one of the biggest advantages of a computerized information system. It processes data and retrieves information at a faster rate.
Common among these many definitions is that MIS represent a collection of technologies, people, and processes that manage the information and communication resources of an organization. Or being able to compare marketing expenditures by geographic location and link them to sales can also improve decision-making. In addition to the skills and knowledge you develop through your coursework, MIS degree programs offer student services that can give you a competitive edge in the job market. MIS can be the means by which information is transmitted such as the Internet , the software that displays the information such as Microsoft Excel , or the systems that manage the data. You can build and maintain computer systems as a network administrator.
Reduced data duplication — database systems are designed in such a way that minimized duplication of data. This means updating data in one department automatically makes it available to the other departments Improved backup systems — with modern day technology, backups can be stored in the cloud which makes it easy to recover the data if something happened to the hardware and software used to store the data Easy access to information — most business executives need to travel and still be able to make a decision based on the information.
The web and Mobile technologies make accessing data from anywhere possible. Disadvantages: It is expensive to set up and configure — the organization has to buy hardware and the required software to run the information system. In addition to that, business procedures will need to be revised, and the staff will need to be trained on how to use the computerized information system.
Heavy reliance on technology — if something happens to the hardware or software that makes it stop functioning, then the information cannot be accessed until the required hardware or software has been replaced. Risk of fraud — if proper controls and checks are not in place, an intruder can post unauthorized transactions such as an invoice for goods that were never delivered, etc. The second era personal computers began in as microprocessors started to compete with mainframes and minicomputers and accelerated the process of decentralizing computing power from large data centers to smaller offices.
In the late s, minicomputer technology gave way to personal computers and relatively low-cost computers were becoming mass market commodities, allowing businesses to provide their employees access to computing power that ten years before would have cost tens of thousands of dollars. This proliferation of computers created a ready market for interconnecting networks and the popularization of the Internet. The first microprocessor — a four-bit device intended for a programmable calculator — was introduced in and microprocessor-based systems were not readily available for several years.
It is arguable that the microprocessor-based system did not make significant inroads into minicomputer use until , when VisiCalc prompted record sales of the Apple II on which it ran. The IBM PC introduced in was more broadly palatable to business, but its limitations gated its ability to challenge minicomputer systems until perhaps the late s to early s.
Computers on a common network shared information on a server. This lets thousands and even millions of people access data simultaneously on networks referred to as Intranets.
The fourth era enterprise computing enabled by high speed networks, consolidated the original department specific software applications into integrated software platforms referred to as enterprise software. This new platform tied all aspects of the business enterprise together offering rich information access encompassing the complete management structure. The fifth era cloud computing is the latest and employs networking technology to deliver applications as well as data storage independent of the configuration, location, or nature of the hardware.
This, along with high speed cellphone and Wi-Fi networks, has led to new levels of mobility in which managers may access the MIS remotely with laptops , tablet computers and smartphones.
The terms management information systems MIS , information system IS , enterprise resource planning ERP , computer science , electrical computer engineering , and information technology management IT are often confused. MIS is a hierarchical subset of information systems.
A management information system (MIS) is a computerized database of financial information organized and programmed in such a way that it produces regular. A management information system (MIS) is an information system used for decision-making, and for the coordination, control, analysis, and visualization of.
MIS are more organization-focused narrowing in on leveraging information technology to increase business value. Computer science is more software-focused dealing with the applications that may be used in MIS. While management information systems can be used by any and every level of management, the decision of which systems to implement generally falls upon the chief information officers CIO and chief technology officers CTO. These officers are generally responsible for the overall technology strategy of an organization including evaluating how new technology can help their organization.
