Who designs a database?

Database approach VS traditional approach?
Database Approach vs. Traditional File ProcessingSelf contained nature of database systems (database contains both data and meta-data).Data Independence: application programs and queries are independent of how data is actually stored.Data sharing.Controlling redundancies and inconsistencies.Secure access to database; Restricting unauthorized access.Enforcing Integrity Constraints.Backup and Recovery from system crashes.Support for multiple-users and concurrent access.
Why is anomalies required in database?
Anomalies are not required in a database. An anomaly is a inconsistency or a problem. A well designed database should not have any anomalies. If there are some, they can cause problems for the users and for the reliability and efficiency of the database.
When designing a database you should reduce duplicate information which is known as .?
When designing a database, you should reduce duplicate information, which is known as normalization. This process involves organizing data into separate tables to minimize redundancy and improve data integrity. By normalizing a database, you can avoid data anomalies and maintain consistency in your data.
What types of anomalies are found in relational database?
There are 3types 1) Update Anomalies 2) Insertion Anomalies 3) Deletion Anomalies
What is database design?

We have a very good business contact database at your company But there seems to be a lot of duplicated records How can you correct this Do you have to build a new database all over again?
It sounds like your experiencing "duplication anomalies". Most anomalies can be prevented by normalizing your database. Third normal form should prevent most anomalies in a simple contact database (look into "3NF" and "normalization"). Basically, duplication anomalies come from flaws in how your table and keys are set up. You may not have to tear down the whole base, but may need to export the data and reconstruct some of the tables. -APMc
