Discuss the historical development of database management systems and logical data models, starting from the file-based system of the past to today. Make sure you explain why databases were developed.
Sure, here is a discussion of the historical development of database management systems and logical data models, starting from the file-based system of the past to today:
File-based systems were the first type of database system. They were developed in the 1960s and were based on the concept of files. Each file stored a single type of data, such as customer records or product inventory. Files were stored on disk drives and were accessed using file management systems.
File-based systems had a number of limitations. They were difficult to manage, as there was no central repository for data. They were also inefficient, as they required multiple copies of the same data to be stored in different files.
