Databse approach advantages and disadvantages

Advantages of the Database Approach If a system failure occurs it is vital that no data is lost. Reduced updating errors and increased consistency. Greater data integrity and independence from applications programs. Improved data access to users through use of host and query languages.

Controlling Data Redundancy In the conventional file processing system, every user group maintains its Databse approach advantages and disadvantages files for handling its data files. Elimination of Inconsistency In the file processing system information is duplicated throughout the system.

Databse approach advantages and disadvantages

So changes made in one file may be necessary be carried over to another file. This may lead to inconsistent data. So we need to remove this duplication of data in multiple file to eliminate inconsistency. To avoid the above problem, there is a need to have a centralize database in order to have this conflicting information.

On centralizing the data base the duplication will be controlled and hence inconsistency will be removed.

In conventional system, availability of information is often poor, since it normally difficult to obtain information in a timely manner because our existing systems are not capable to produce the same.

Once several conventional systems are combined to form one centralized database, the availability of information and its updateness is likely to improve since the data can now be shared and DBMS makes it easy to respond to anticipated information requests.

Centralizing the data in the database also means that user can obtain new and combined information easily that would have been impossible to obtain otherwise. Flexibility of the System is Improved Since changes are often necessary to the contents of the data stored in any system, these changes are made more easily in a centralized database than in a conventional system.

Applications programs need not to be changed on changing the data in the database. Integrity can be improved Since data of the organization using database approach is centralized and would be used by a number of users at a time, it is essential to enforce integrity-constraints.

Advantages and Disadvantages of Database Management System – Equizine

In the conventional systems because the data is duplicated in multiple files so updating or changes may sometimes lead to entry of incorrect data in some files wherever it is applicable. Even if we centralized the database it may still contain incorrect data.

A student may be shown to have borrowed library books but has no enrollment. The above problems can be avoided by defining the validation procedures whenever any update operation is attempted. Standards can be enforced Standards are easier to enforce in database systems because all the data in database is access through centralized DBMS.

Here standards may relate to the naming of data, structure of data, format of the data etc. Standardizing stored data formats is usually desirable for the purpose of data interchange or migration between systems.

Security can be improved In conventional systems, applications are developed in an adhoc manner. Often different system of an organization would access different components of the operational data, in such an environment enforcing security can be quiet difficult. Setting up of a database makes it easier to enforce security restrictions since data is now centralized.

It is easier to control who has access to what parts of the database. Different checks can be established for each type of access retrieve, modify, delete etc. So it may become necessary to ignore some requests for information if they conflict with higher priority need of the organization.What Are The Disadvantages And Advantages Of Database Management System?
