What are anomalies in database?
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.
What is a database system and write atleast five features of good database system?
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.
What are anomalies in DBMS and their types?
Tables that have redundant data have problems known as anomalies.So data redundancy is a cause of an anomaly. Redundancy is the duplicaion of the data. There are 3 types of anomalies. Insert Anomaly:When you insert a record without having it stored on the related record. Delete Anomaly:When you delete some information and lose valuable related information at the same time. Update Anomaly: Any change made to your data will require you to scan all records to make the changes multiple time.
