In DBMS the data is stored in the form of table . Each row in DBMS is known as tuple.

Dealing with a single table.

Cardinality is the number of attributes in the table.

TUPLE : Is the "ROW" in a table

In DBMS a table contains one or more columns there columns are the attribute in DBMS FOR EXAMPLE---say you have a table named "employee information"which have the following columns ID,NAME,ADDRESS THEN id ,name address are the attributes of employee..................

A key is an attribute that is used to get data from a table

1:In DBMS joining between table is not possible 2: Does not support Networking

It is a constant value that gives the name, structure of table and the constraints laid on it.

DBMS actually manages the storage, without DBMS you have to explicitly store the table definition and its contents in a file and retrieve it. This is a headache if there are many tables, this process is simplified by the software called DBMS, using this you can query the tables. query is nothing but calling the functions of the program called DBMS, if you want even you can create your own DBMS in c , java etc and have your queries defined in the form of functions.

A DBMS stores data in a table where the entries are filed under a specific category and are properly indexed. This allowed programmers to have a lot more structure when saving or retrieving data. A relational database contains data in more than one table. Each table contains a database that is then linked to other tables with respect to their relationships.

There is no set limit (at least, in any of the DBMS I'm aware of), however as there is a limit as to the number of columns a table can have (said limit varying from DBMS to DBMS), there is a theoretical limit. That said, in practical terms, a table can have as many as it needs. However, performance of inserts/changes/deletes may suffer if an excessive number is present, since referential integrity must be checked on each.

They have their own DBMS called Big Table. Follow thi slink to know more:

If the dropped table is a base table for a view , then dbms like oracle invalidates these dependent views but does not drop them. But you cannot use these unless you re-create the table.

It is a pool of data through which data are enter into into the table for data management.

Data is represented/organized in a dbms in the form of Schemas, tables, rows and columns One DBMS may have multiple Schemas One Schema may have multiple tables One table may have multiple rows One row may have multiple columns If these tables are related to one another it forms a RDBMS - A Relational DBMS

Normalisation means make table very effective and usable means make table atomic ,unique primary key,not redundancy etc.

no, Java is not dbms.. Java is a programming language Dbms is database

DBMS is Database management system .Database design is very important in DBMS, It serves as a foundation of DBMS.

A DBMS contains a set of Schemas, tables and views that are used to stored/organize user information logically. The user has options to view, insert, update and delete the data present in the tables.DBMS Schema 1 Table 1 Column 1Column 2Column 3...Table 2Table 3...Schema 2Schema 3...

Microsoft Excel is not a DBMS. It is a spreadsheet application. A DBMS is a database management system. While Excel does have some database capabilities, it is not a DBMS.

DBMS is Database Management System.
