,data dependence

contains the data definition as well as their characteristics and relationships. A data dictionary
may also include data that are external to the DBMS. Also known as an information resource
dictionary. See also active data dictionary, metadata, and passive data dictionary.
data inconsistency
A condition in which different versions of the same data yield different (inconsistent) results.
data independance
A condition in which data access is unaffected by changes in the physical data storage
characteristics.
data integrity
In a relational database, a condition in which the data in the database complies with all entity
and referential integrity constraints.
data management
A process that focuses on data collection, storage, and retrieval. Common data management
functions include addition, deletion, modification, and listing.
data processing (DP) specialist

general-purpose databases
A database that contains a wide variety of data used in multiple disciplines.
hub
A warehouse of data packets housed in a central location on a local area network. It contains
multiple ports that copy the data in the data packets to make it accessible to selected or all
segments of the network.
Information
The result of processing raw data to reveal its meaning. Information consists of transformed
data and facilitates decision making.
islands of information
In the old file system environment, pools of independent, often duplicated, and inconsistent
data created and managed by different departments.
knowledge
The body of information and facts about a specific subject. Knowledge implies familiarity,
awareness, and understanding of information as it applies to an environment. A key
characteristic is that new knowledge can be derived from old knowledge.
