A database is a collection of data organized for easy access and manipulation, while a relational database is a type of database that stores data in a structured format using tables that are related to each other through keys. In a relational database, data is organized into rows and columns, and relationships between tables can be established using keys.
Data anamaly means same type of data present in database as a duplication.So while updating or modifying the information in the database we gets the problem of data inconsistency to solve this problem we need to remove the duplicated data
Data type, or more commonly datatype as it related to database management systems is the phyisical format by which the data in a database managment is stored on the computers harddrive. The datatypes are database specific. In general, you need to have the same datatype to be able to compare, sort, append data. Data that is not of the same type needs to be CAST or converted to the other datatype before such operations on the data can be performed. Many times this conversion is internal, but in some database management systems, you ned to explicitly convert the data.
