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
Anomalies is the data within the database; it is the copy of the original data it needs to be updated in order to avoid problems such as viewing the website. There are four types of anomalies which are Insertion anomaly, Deletion anomaly, Duplicate entry and Modify (Update anomaly). Insert anomaly is the entity that relates to another entity within the table. If the data doesn't relate to another entity then there is no point of entering it, therefore a unique data is needed to identify a particular data to insert the data that relates with it such as employee ID number. Example of insert anomaly: If any company's manager need to insert their employee salary to the employee's ID, they then need to make sure that the employee id is correct otherwise, if it's wrong then they will give unfair salary to their employee by which they will have bad name onto their company.
ranges of database
Database is defines as a collection related records/data. When the data in the database is grouped based on some classification it is called database clustering.
Relational Database Model
Database file is one that is stored on a server and it is in the format that the database needs to read it. It is also stored in the database catalog. A flat file is one that is dumped from a database to import or export into another database or program. A flat file is fields of data separated by delimiters, which keep the fields separated for export/import.
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.
Database is a collection of interrelated data. Database management system is collection of data and a set of programs to access and modify that data. There is a technique called normalization used to make good database design. Normalization helps to reduce redundancy from the data. There are different normal forms, each normal form is used to make database in standard form that is free of problems. If database is not designed well, it exhibits following problems called Update Anomaly. there different types of anomaly exists and they are as follows: Insertion anomaly: It is difficult to insert required data as not availability of other data. Deletion anomaly: We can not delete unnecessary data cause as we delete those data necessary data will also be deleted. Update Anomaly: We can not update attribute in a table because there may different values for the same attribute in same table. There are several advantages of DBMS, and they are as follows: - data can be retrieved easily and quickly, - easy to impose integrity constraints, - no redundancy, - easily to maintain ACID property of transaction - easily to update data.
