information management
Quick Summary
Information processing involves acquiring, recording, organizing, retrieving, displaying, and disseminating information. While the term "information" can broadly refer to facts and opinions, in computing, it specifically relates to data handled by computers.1
Information management (IM) focuses on the capture, digitization, organization, and presentation of data. Computers use auxiliary disk storage for permanent data storage, which is slower but has higher capacity than main memory. IM systems develop efficient algorithms to store and retrieve data for processing, often using databases composed of files, records, and fields.2
These systems can be sequential or allow random access using indexes. Various database models exist, including hierarchical, network, and relational, with relational databases storing data in tables. Database management systems (DBMS) like MySQL manage this data. Modern IM also includes NoSQL databases and object-oriented approaches. Data integrity and concurrency control are crucial for maintaining data accuracy and managing simultaneous user access. Information systems support various organizational functions, including management, through reporting, decision support, and business intelligence applications.234
