It is a group of interrelated data that is stored in a data base server. They are usually stored in the form of tablets. The basic aim of the database is to provide a path to store and retrieve the database information in an efficient and fast manner.
It has different features that differ from the traditional file system. In case of file system approach it requires each user to define and implement the required files to run a specific application. As the program is run and saved by the different users in different computer it consumes more space and replicates or redundancy of data may lead to confusion where the sharing of data is not possible between two users.
In case of database system concept, we have single repository where it is defined once and accessed by more number of users. Fundamental characteristic contains data along with the definition and description. It is stored in a system catalogue where it contains definition and structure of the database. Data stored in the catalog is called as Meta data. This approach will work on the different types of database such as banking database, airlines, and finance along with the enterprise information database.
If you are working in windows seven it will rearrange database icons regularly. The main reason for the rearrangement of database icon is due to the reason that the desktop forgets the icon position in your screen, as it is stored in the database it actually positioned. When the windows gets confused with its position then it automatically leads to rearrangement.
First thing need to solve the program is to click on the “Auto Arrange icons” option present in your system. Most of the computers are enabled with this option. To select this option you need to click on view and then check out whether the “auto arrange” option is selected.
Incase if your system does not have the auto arrange then look for the alternative icon called as “ align Icons To Grid” this will basically link will get attached with other part of computer incase if it gets corrupted or damaged.
After restarting the PC check out whether the problem is solved or if the problem exists then try out the registry cleaner to clear the problems as the registry contain the email, desktop wall paper along with the login details as registry is responsible for maintain the desktop icons. So it is essential to clean up the registry cleaner by scanning the database and then fixing the database.
Types of databases
Internet makes use of the database in one or the other form. The method of dramatically improving pages from the database is very useful to meet out the requirement. So it is important to know about the different types of database. This database usually comes in two forms first one is single or flat file and the second one is Multi-file relational database model or structure database where these database is formed on the basis of four factors.
Amount of data required to proceed and stores the large determines that sits your database in future.
Complexity of Data:
Another factor used to determine the database type its level of complexity based on the available data. Data might be an image, plain text or the sound files.
Number of Users:
Number of users accessing the system and then amend data continuously where it acts as a determining factor.
Action to be performed on the data
First determine the available data to be exported or imported from the different IT system.
