Aggregation: Selecting the data in group of records is called aggregation.
There are five aggregate system functions they are viz. Sum, Min, Max, Avg, Count. They all have their own purpose Decomposition: Selecting all data without
any grouping and aggregate functions is called Decomposition. The data is selected, as it is present in the table.
Generalization: while generalization seems to be simplification of data, i.e. to bring the data from Un-normalized form to normalized form.
A faulty generalization is a statement that's not true while a valid generalization is a true statement.
Generalization can be defined as a broad statement that is applicable to a group of people.
The steps on making a generalization is Identify the topic,Gather examples,examine the examples for similarities,and make the generalization.
Generalization helps the reader understand a character or idea in the story.
you need to include all of the details in making your generalization
Decomposition is the breaking down of living organisms. It is a natural occurance of the organisms rotting. If it were not for decomposition the world would be covered in trash. FOR RDBMS There are five aggregate system functions they are viz. Sum, Min, Max, Avg, Count. They all have their own purpose Decomposition: Selecting all data without any grouping and aggregate functions is called Decomposition. The data is selected, as it is present in the table.
yes it is a rdbms
what is rdbms and its application
what is the use of queues in rdbms
1. relational database management system(RDBMS) 2. object Rdbms. 1. relational database management system(RDBMS) 2. object Rdbms.
advantage of rdbms over dbms
AnswerMySQL, like most modern Database Management Systems is based on the relational model. So it is a RDBMS (Relational Database Management System).
RDBMS is all about Relational Data Base Management System...
no these are aggregations of lymphoid tissue
An Object RDBMS is a relational database and it is part of an object-relational database. AN RDBMS might involve SQL statements with functions and user-defined data-types.
every rdbms is a dbms.as of a standard there is a criteria for any prog. lang. to become rdbms. this is defined in codds 12 rules. this all together if satisfied then any prog lang can be said to be a rdbms. but in practice we come across many examples where a prog lang is not rdbms but still provide relational database very often. ex foxpro is not rdbms because it does not satisfy one of the codds 12 rule i.e. of defining a foreign key. in foxpro you cannot define a foreign key. but since it has tables in it and can provide relations we can term foxpro as pseudo rdbms(partial rdbms)..........
No, but some RDBMS's are available on multiples OS's (Oracle, for example: Windows, unices, bs2000... ).
