One of the major problems with this system was data redundancy and inconsistency. Since the files and programs jammed into files were created by several different programmers over a long period of time, the files were certain to be in different formats, involving several different programming languages. Most of the information is also constantly duplicated due to how tedious it would be to access others’ code and double check the information. For example, if a customer of a bank has two accounts, the data accompanied by these accounts would be stored in two separate files in order to satisfy both accounts as they are made. This leads to data redundancy. This would lead to bigger storage sizes for the same information, increasing the cost.
