Document Summary

Up until now companies had unintegrated information systems that supported only the activities of individual business functional areas. This configuration of information system is called silos because each department has its own stack, or silo, of information that is unconnected to the next silo. Computer hardware and software has grown rapidly in the 1960"s to the 1970"s. Moore"s law states that the computer chip doubled every 18 months. This means that the capabilities of computer hardware were doubling every 18 months. In the 1970"s relational database software was developed, which allows business to store, retrieve, and analyze large volumes of data (ex: spreadsheets) By the mid 1980"s, telecommunication developments allowed users to share data and peripherals on local networks. The central computer-local computer arrangement is now called a client-server architecture. The computers eventually got more power allowing a larger scalability, meaning that when the equipment"s capacity is exhausted, its capacity can be increased by adding new hardware.
