Data Mining
Data mining is a class of database application that looks for hidden patterns in a group of data that can be used to predict future behavior. For example, data mining a database of debtors can help collection agencies find debtors with common attributes.
Database
In computing, a database can be defined as a structured collection of records or data that is stored in a computer so that a program can consult it to answer queries. The records retrieved in answer to queries become information that can be used to make decisions. The computer program used to manage and query a database is known as a database management system (DBMS).
Database Server
A database server is a computer program that provides database services to other computer programs or computers, as defined by the client-server model. The term may also refer to a computer dedicated to running such a program. Database management systems frequently provide database server functionality.
DBMS
A database management system (DBMS) is computer software designed for the purpose of managing databases. Typical examples of DBMSs include Oracle, DB2, Microsoft Access, Microsoft SQL Server, Postgres, MySQL, Sybase and FileMaker. DBMSs are typically used by database administrators in the creation of database systems.
Direct Inward Dialing (DID)
DID is a feature offered by telephone companies for use with their customers' PBX system, whereby the telephone company allocates a range of numbers all connected to their customer's PBX. As calls are presented to the PBX, the number that the caller dialed is also given, so the PBX can route the call to the desired person or bureau within the organization.
Disk Mirroring
Disk Mirroring is the replication of logical disk volumes onto separate logical disk volumes in real time to ensure continuous availability, currency and accuracy. A mirrored volume is a complete and separate copy of a logical or physical disk volume.
Distributed Application
A distributed application is an application made up of distinct components running in separate runtime environments, usually on different platforms connected via a network. Typical distributed applications are two-tier (client-server), three-tier (client-middleware-server), and multi-tier (client-multiple middleware-multiple servers)
DNIS (Dialed Number Identification Service)
A dialed number identification service is a service sold by telecommunications companies to corporate clients that lets them determine which telephone number was dialed by a customer. This is useful in determining how to answer an inbound call.
DNS (Domain Name System)
On the Internet, the Domain Name System associates various sorts of information with so-called domain names; most importantly, it serves as the "phone book" for the Internet: it translates human-readable computer hostnames into the IP addresses that networking equipment needs for delivering information.
