Many Common ICT Systems have different functions, of which they have names. All businesses, schools and organisations will often require some computer system, even registration or time management. However often these systems are financially concerned and for that reason are often automated.

Legacy Systems

Maintain the older applications for customers who still use them. They are maintained until they become depreciated and service systems that are older or out of date. It is likely that this system has been used for a long time and it would be impractical to upgrade without replacing it being expensive, disruptive or not worthwhile. Financial systems may keep their systems records for significantly longer amounts of time than other departments to monitor progress etc.

Back office systems

Maintain the business itself. They are situated elsewhere from the front-facing aspects of a business and whose role it is to keep the business working effectively. A back-office system resides in a ‘back office’ and as such doesn’t usually interact with any customers. The goal of back office systems like finance and IT is to service the other departments of the business and keep the business running effectively.

Day-to-day working systems

A transaction processing system

A system that manages and maintains the records of transactions and payments, they crucially have to be up-to-date at any time. Often on large-scale systems, this can be difficult to keep accurate, so caching is used.

Customer Relationship Management Systems
