What are the characteristics of relational data base management system?

RDBMS is all about Relational Data Base Management System...

It is a data base that have relationships ie:: what is relationship between two objects

there are certain rules to make up a relational data base management system, oracle follows it and so its an rdbms

dbms stands for data base management system whereas rdbms is relational data base management system. A Database Management System (DBMS) is collection of software programs which enable large, structured sets of data to be stored, modified, extracted and manipulated in different ways. Whereas Relational Database Managemet System (RDBMS) is a data structured in database tables, fields and records. Each RDBMS tables consist of database table rows.

RDBMS is a Relational Data Base Management System Relational DBMS. This adds the additional condition that the system supports a tabular structure for the data, with enforced relationships between the tables. This excludes the databases that don't support a tabular structure or don't enforce relationships between tables.

RDBMS is also known as Relational data base management systems.Its advantages is data is guarantees to be consistent.

database system is organized collection of data.data base management is a software and ti controls the data in a data base.

Data Base Management System

data base means a collection of data,which may be inter related. data base management system is a collection of programs for managing the data base.

Data base management system

Data Base Management System

Data Base Management System is a set of software programs (package) that controls the system organization, creation, storage, management, maintenance, usage and retrieval of data (from a set of tables or dataset) in a database.

DBMS can be classified in the following ways, 1. Based on Data Model Relational Data Model Object Data Model Object Relational Data Model Extended Relational Data Model XML Model Hierarchical Data Model Network data Model 2. Based on Number of Users Single User System Multi-User System 3. Based on Number of Sites Centeralized systems Distributed DBMSs(DDMSs) Homogeneous DDMS Hetrogeneous DDMS

Very Large Relational Data Base

RDBMS : Relational Data Base Management System. To achives consistance of Data via referntial integrity. It facilitates to give relation ship between tables. Like foreign key relationship , on delete cascade etc...

The degree of a relation is the number of attributes the relation has in it. The degree of a relation can be zero or more integer. An n-ary relation is a relation in which its degree is n in turn a relation of n attribute(s).

data is like the files that are put on table .while data base system is a system which is base on data and query.

Data Base Management System.

In many cases, each company has its own database (or several databases), so I would estimate that there are about as many databases as there are companies. If you are referring to the DBMS - the software that manages the databases - you can see a list of the most common ones in the following Wikipedia articles: * Comparison of relational database management systems * Comparison of object database management systems * Comparison of object-relational database management systems

Yes ,DBMS -data base management system

There are currently 3 general categories of data base management systems in use today: relational database systems multidimensional database systems (often referred as 'cubes') object oriented database systems Prior to the success of relational database systems (early 80's) there were also hierachical database systems and network (aka CODASYL) database systems.

A Data Base Management System (DBMS) is a generic term like tin of food. Microsoft Access (msaccess) is a relational database (RDBMS). There are also network, hierarchical, OLAP and other types of databases. So msaccess is a DBMS but not the other way around.

Because relationships can be set up between tables in Microsoft Access to create what are known as relational databases.

An expert system is intended to solve specific problem as if it is a human. It uses base of rules (knowledge base) and algorithms to reach a decision or conclusion. It may be built as from-scratch software or using a content management system software/technology. A learning content management system literally means any content management system for learning purposes. If it includes a thinking component (i.e inference engine), then the content represents the knowledge-base, and it may produce step-by-step explanation of how the decision or conclusion is reached. The purpose of such knowledge-base learning content management systems is to support the learning process, rather than to make decisions for real-world problems.

The word relational is also used somewhat inappropriately by several vendors to refer to their products as a marketing gimmick. To qualify as a genuine relational DBMS, a system must have at least the following properties (Note 1): 1. It must store data as relations such that each column is independently identified by its column name and the ordering of rows is immaterial. 2. The operations available to the user, as well as those used internally by the system, should be true relational operations; that is, they should be able to generate new relations from old relations. 3. The system must support at least one variant of the JOIN operation. Although we could add to the above list, we propose these criteria as a very minimal set for testing whether a system is relational. It is easy to see that some of the so-called relational DBMSs do not satisfy these criteria. We begin with a description of Oracle, currently one of the more widely used RDBMSs. Because some concepts in the discussion may not have been introduced yet, we will give references to later chapters in the book when necessary. Those interested in getting a deeper understanding may review the appropriate concepts in those sections and should refer to the system manuals.
