Define domain with respect to dbms?
In database technology, domain refers to the description of an attribute's allowed values. The physical description is a set of values the attribute can have, and the semantic, or logical, description is the meaning of the attribute.

Active database management systems (active DBMS) support the definition, management and execution of event/condition/action rules specifying reactive application behavior. Alt…hough the advantages of active mechanisms are nowadays well known, there is still no wide use in practice. One main problem is that especially for large rule sets, defined by different persons at different points in time, potential conflicts and dependencies between rules are hard to predict and rule behavior is difficult to contro

each column contains same type of data thus when you select a data type for a particular domain then DBMS will not accept any value of other data type. Further information …contributed by Ramona Maxwell. Please visit www.sqlsolver.com: Domain constraints are a user-defined data type which enforces the integrity of the standard data types. A domain consists of all values permitted in a column. In constructing your database you would first select a standard data type such as VARCHAR or INT. You could then constrain or limit the data using NOT NULL, UNIQUE, CHECK, PRIMARY KEY or FOREIGN KEY. For example the CHECK constraint could limit INT data within your domain [column] to numbers less than 5000. You would thus define a custom data type using domain constraints.
It can be defined as an area that is bounded by or infused with powerful spiritual energy under the control of a supreme divinity. The following comes from author Daryl Gon…yon: Our Spiritual Domain involves other spirits, or souls, that God has given us that we can see, hear, or who enter our mind. Not only are we the only persons with our unique DNA and fingerprints, we are one of a kind with our Spiritual Domain. No one else in the entire world has the same Spiritual Domain as do we. In God's eyes, we are supremely special, and He has given us a Spiritual Domain unlike any other person in the world. He has strategically placed us all around the world with our unique Spiritual Domain. We live in this place, this neighborhood, this country, amongst these people, and at this particular time in our life. It is within this Spiritual Domain that we will find our destiny.
\ni am also having the same doubt please tell me the answers if u know
it contains meta data A sub system that keeps track of the definitions of all data items in the database,relationships that exits between various data structures, indexes th…at are used too access data quickly,screen and report format definitions that may be used by various application programs.
Domain is the range of values that an attribute can possess.
dBm means "decibels relative to 1 mW". B is the symbol for the unit bel, and decibel is 1/10th of a bel. Bels are used to measure ratios between two measurements, not an absol…ute measurement by themselves. In this case you're measuring relative to 1 mW. So, for instance, if a device is producing 100 mW, this will be 100 times your reference of 1 mW. "100 times" the power is equal to 20 decibels, so this would be 20 dBm.

Let the function be f(x) = 1/(x-1) The domain is all allowable values for which the function can be defined. Here, except 1, any number would give the function a meaningfu…l value. If x=1, the denominator becomes 0 and the function becomes undefined. Therefore, the domain is all real numbers except 1. The range is all values assumed by the function. Here, the range is negative infinity to plus infinity (that is , all real numbers).

Respect is defined by how you give and show respect. If you respect yourself there is a good chance that you will have respect for others. If you don't show respect for others… than no one would respect you.
