A join is a temporary relationship that you can create between two tables in a database query that do not already have an established relationship or common field with t…he same fieldname or data type. Database tables that are joined in a query are related in that query only, and nowhere else. The type of join that you use indicates which records the query will select or perform the chosen actions on.
Entitie are the principal data object about which information is to be collected. Entities are usually reognizable concepts,either concrete or abstract, such as: person,univer…sity,employees etc.
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, dBm 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.

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) .
Data Base Management System
Each simple attribute of an entity type is associated with a value set (or domain of values), which specifies the set of values that may be assigned to that attribute for each… individual entity. If the range of ages allowed for employees is between 16 and 70, we can specify the value set of the Age attribute of EMPLOYEE to be the set of integer numbers between 16 and 70. Similarly, we can specify the value set for the Name attribute to be the set of strings of alphabetic characters separated by blank characters, and so on. Value sets are not displayed in ER diagrams, and are typically specified using the basic data types available in most programming languages, such as integer, string, Boolean, float, enumerated type, sub-range, and so on.
Simply stated, that is an acronym for an advanced 'Database Management System', which is a software package that would facilitate the development of various applicable databas…es. See the related link listed below for more information:

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.
