This ranking of results is a key difference of information retrieval searching compared to database searching. [2]
The "software" for pre-computer information systems included how the hardware was prepared for use (e.g., column headings in the ledger book) and instructions for using them (the guidebook for a card catalog). Data: Data are facts that are used by systems to produce useful information. In modern information systems, data are generally stored in ...
