These pointers, called linked lists in many approaches, are difficult for the developer to maintain.Īny time someone adds information to the database, the pointers have to be updated to show the next piece of information and the previous set of information. Flat files use techniques such as keeping track of pointers from one set of information to another. Werbung The approach of a flat file database is contrary to the approach of a relational database, in which how information is stored does not matter how it is retrieved does.
