Businesses use information systems at all levels of operation to collect, process, and store data. Management aggregates and disseminates this data in the form of information needed to carry out the daily operations of business. Everyone who works in business, from someone who pays the bills to the person who makes employment decisions, uses information systems. A car dealership could use a computer database to keep track of which products sell best. A retail store might use a computer-based information system to sell products over the Internet. In fact, many businesses concentrate on the alignment of MIS with business goals to achieve competitive advantage over other businesses. MIS professionals create information systems for data management such as storing, searching, and analyzing data. In addition, they manage various information systems to meet the needs of managers, staff and customers. By working collaboratively with various members of their work group, as well as with their customers and clients, MIS professionals are able to play a key role in areas such as information security, integration, and exchange. As an MIS major, you should have better knowledge to design, implement, and use business information systems in innovative ways to increase the effectiveness and efficiency of your company.
