Compute-based information systems have been in widespread use since the 1990s in industry, non-profit organisations and government agencies. These systems provide fast, centralised access to databases of personnel information, reference reading, best practices and on-the-job training, and are easily customisable to meet an organisation's needs. With the Internet and technology boom of the early 21st century, use of computer-based information networks is growing faster each year.
Access to data via a computer network information system is central, providing a "one-stop" location to find and access pertinent computer data. Most large-scale businesses and organisations use some sort of central database to manage user information, manage advertisement lists, store product information and keep track of orders. Examples of central database solutions are MySQL, PostgreSQL or Microsoft SQL database solutions, coupled with custom software which provides user interfaces.
Central information systems provide organisations with the advantages of having large amounts of data, covering many different fields, all accessible via a central source. Information coverage is a huge advantage for any organisation, because having vast amounts of useful data from every different department streamlines access and increases productivity. For users, having access to a networked information system is analogous to having a digital library of shared knowledge. Recent developments in database information systems link company information access with larger databases of academic and professional research, such as Google Scholar, to provide even more information capability to personnel.
Efficiency of access is a crucial advantage to networked information systems over more traditional information management systems, such as paper cataloguing and filing. Computer-based information systems catalogue and file documents in a set logical way, making data access very efficient and fast. Data can be manually categorised, and filters created to automatically file documents that match certain patterns. This increases employee productivity time by allowing workers to focus more on the task at hand rather than filing paperwork.
Computer-based information systems are completely extensile and customisable to an organisation's needs. Upon installation, customised computer information systems use configuration files that are tailor-made to an organisation's needs to file and categorise data. Computer software engineers frequently design custom database interfaces and information storage/recovery systems for enterprise clients. As a company grows, modifications and additions to this filing configuration allow easy extensibility. Computer information systems are not limited in scale or possibility. They are uniquely designed for maximum organisational benefit for each customer.
