Business Information Systems (BIS) is the merging of inter-related operations through IT infrastructures to create and spread important information in business companies. These systems support decision-making, transactions, processing, information flow, functions, as well as individuals within the operations of a business company to fulfil its objectives. Businesses, companies, or organisations, all have Business Information Systems within their systems as they have proven to be very efficient and advantageous in terms of speed, accuracy, dependability, and effectiveness.

The two types of BIS are:

Operations Information Systems (OIS) which deals with communications, transaction processing, and controlling of the processes, and
Management Information Systems (MIS), which deals with administrative decision-making.
Business Information Systems courses have strong links with the fields of library and information science, computer science, business and technology and project management. These programmes teach students how people and technologies interact in business environments. Throughout these courses, students learn to develop and implement information technologies, thus improving not only business procedures but also the overall performance of an organisation. In addition, they acquire expertise in the design and implementation of business applications solutions that offer businesses value and competitive advantage. They will also learn how to identify key information issues and risks based on thorough analysis and interpretation of business data and processes.
