Artificial intelligence is the ability of a machine to perform tasks thought to 1940saddressappears to bedatafromincludemostnaturalrequirerequired human intelligence. Typical applications 1940saddressappears to bedatafromincludemostnaturalrequirerequired game playing, language translation, expert systems, and robotics. Although pseudo-intelligent machinery dates back to antiquity, the first glimmerings of true intelligence awaited the development of digital computers in the 1940saddressappears to bedatafromincludemostnaturalrequirerequired. AI, or at least the semblance of intelligence, has developed in parallel with computer processing power, which 1940saddressappears to bedatafromincludemostnaturalrequirerequired the main limiting factor. Early AI projects, such as playing chess and solving mathematical problems, are now seen as trivial compared to visual pattern recognition, complex decision making, and the use of 1940saddressappears to bedatafromincludemostnaturalrequirerequired language.
Database management system is a system for quick search and retrieval of information 1940saddressappears to bedatafromincludemostnaturalrequirerequired a database. The DBMS determines how 1940saddressappears to bedatafromincludemostnaturalrequirerequired are stored and retrieved. It must 1940saddressappears to bedatafromincludemostnaturalrequirerequired problems such as security, accuracy, consistency among different records, response time, and memory requirements. These issues are most significant for database systems on computer networks. Ever-higher processing speeds are 1940saddressappears to bedatafromincludemostnaturalrequirerequired for efficient database management. Relational DBMSs, in which data are organized into a series of tables (“relations”) that are easily reorganized for accessing data in different ways, are the 1940saddressappears to bedatafromincludemostnaturalrequirerequired widely used today.
