What is the dbm?
DataBase Management System (DBMS) is a software package that allows data to be effectively stored, retrieved and manipulated and the data stored in a DBMS packege can be ac…cessed by multiple users and by multiple application programs like (SQL Server, Oracle, Ms-Access) ..
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.
dbms- database management systems............. it is a collection of interrelated data and the set of programs to access those datas........ it is used to meet the disadvant…ages of the file systems........ there are many disadvantages of filesystems........ lik,, data redundancy and data in consistency, difficulty to access data,integrity problems, atomicity problems.............. dbms is quite complicated but better than file systems
Data Base Management System
\nData Definition Facilities - CREATE and DROP. \nData Manipulation Facilities - SELECT, INSERT, UPDATE and DELETE.\nHelp Facilities - MS Access provides helpful wizards to al…low 'novice' users to do a task or even 'expert' users to do it easier.\nReporting Facilities - Creating professional looking reports from SELECT statements, another good example of this is MS Access.\nData Control Facilities - Permissions, GRANT. Views, CREATE VIEW, etc.\nMulti-user Functionality - Allowing more than one user to access the database simultaneously. Including concurrency controls such as locking part of the database that is being updated.\nDistributed Databases - Distribute the database over several sites.\nCASE Tools - Computer-aided Software Engineering is the automation of the development of software systems. An example of this are the easy tools provided in MS Access and Oracle to create forms for a database.\n. \nI'm sure people can add more, but these are what I see as the main functions.
Database Management System DBMS is used to store information in the form of tables columns and rows, interconnected by keys and accessible throughout an interface. Examples: …SQL, MYSQL, ORACLE, etc ...
P(dBm) = 10log 10 (10mW) = 10dBm
1. To manage record of information in a desired manner. 2. Provide easy access to user. 3. minimum redundancy. 4. provide easy way to upgrade data.
dbms is data base management system .It is combination of the data base & the the softwares to access the data from the database. eg:Poracle 91,dbase; for more reply to rexrer…email@example.com
Not really, but now a days, every software that deals with data storage, has some feature of DBMS.

DBMS Benefits 1.Improved strategic use of corporate data 2.Reduced complexity of the organization's information systems environment 3.Reduced data redundancy and inconsi…stency 4.Enhanced data integrity application-data independence 5.Improved security 6.Reduced application development and maintenance cost 7.Improved Flexibility of information systems 8.Increased access and availability of data and information 9.Logical and physical data independence
DBMS stands for data base management system. DBMS is a collectionof programs that enables users to create and maintain a database.The DBMS is a general purpose software system… used to facilitatethe process of defining, constructing and manipulating data basesfor various applications. features of DBMS: 1.Data independence 2.Efficient data access 3.Data integrity & security 4.Data administration 5.Reduced application development time
DBMS is database management system and it stores data that are related. DBMS maintains data security and integrity as well.
