The following are the basic steps of creating databaseFigure out why you need database-:This is the first step in creating database which decide reason for creating database example creating database for store dataSelect type of software which used for creating database example Microsoft access ,database oracle MySQL database.determine your field in data base this include column and low of the databasecreate a table for each portion of databasegroup your field into tableenter the data into your database.
only one relationship can exists between two tables in the MS ACCESS software
In database system the data is stored in the form of table. So to store the data in the database, table are very important in a database system.
To represent data in an understandable way.Enhance an individuals understanding of the database.Facilitate efficient conveyance of database details between database stakeholdersProvide a point of reference for database designers to extract database specificationsDocument the database for future reference and provide a means for collaboration
I think "TABLE" is the main building block of relational database
A distributed database is a database in which portions of the database are stored on multiple computers within a network. Users have access to the portion of the database at their location so that they can access the data relevant to their tasks without interfering with the work of others. A centralized distributed database management system manages the database as if it were all stored on the same computer.
(computer science) A database maintained in physically separated locations and supported by a computer network so that it is possible to access all parts of the database from various points in the network.
The database can be of two types either distributed or centralized . In distributed database the data is in different systems. In centralized database the data is in a single central system.We can categorize database as either distributed or centralized . In centralized database the data is in a single centralized system. While In distributed database the data is in different systems .
As we know a database is used for storing data. A database may be centralized or may be distributed. A distributed database is one in which data is distributed in different systems.
Distributed Database Consulting was created in 1997.

Distributed and Centralized Databases Distributed data is defined as collection of logically distributed database which are connected with each other through a network. A distributed database management system is used for managing distributed database. Each side has its own database and operating system.A centralized database has all its data on one place. As it is totally different from distributed database which has data on different places. In centralized database as all the data reside on one place so problem of bottle-neck can occur, and data availability is not efficient as in distributed database. Let me define some advantages of distributed database, it will clear the difference between centralized and distributed database.Users can issue commands from any location to access data and it does not affect the working of database. Distributed database allows us to store one copy of data at different locations. Its advantage is that if a user wants to access data then the nearest site (location) will provide data so it takes less time.There are multiple sites (computers) in a distributed database so if one site fails then system will not be useless, because other sites can do their job because as I earlier said that same copy of data is installed on every location. You will not find this thing in centralized database.Any time new nodes (computers) can be added to the network without any difficulty.Users do not know about the physical storage of data and it is known as distribution transparency, as we know that ideally, a DBMS must not show the details of where each file is stored or we can say that a DBMS should be distribution transparent.
The importance of a distributed database in that it allows for easy expansion and increased reliability . A distributed database does not contain all the information stored on one disk or attached to one CPU.
