dBm is decibel power unit referenced to 1 milliwatt. Look at the related links for conversion: voltage to dBm, dBu, and dBV.
it is the power ratio in decibels No, it isn't. dB on its own is a ratio. But when dB has a suffix, the figure is an absolute measurement, not a ratio. For instance, d…Bm is a measurement of power compared to 1mW. 0dBm means zero difference between 1mW and the measured figure. In other words the measured figure is also 1mW. 3dBm is 3dB greater than 1mW. -3dB is 3dB less than 1mW. etc. Another suffix is W. 0dBW being 1 watt. There are many more suffixes, some of which are used in only a few specialised cases.

A DBMS snapshot in Oracle can also be referred to as a materialized view. Basically a snapshot is a refreshable view that can be refreshed on command or commit.
class in dbms is nothing but a collection of attributes.... class in java is defined as collection of objects....:D
DBMS is database management system and it stores data that are related. DBMS maintains data security and integrity as well.
