records are more complete and consistent when a DBMS is used to maintain data what does consistency of data imply
Answers
Answer:
Consistency of data implies no duplication or mismatching of data.
Explanation:
For example in a database of students there may be many tables (one for marks in a subject, maybe one for details about students etc). Suppose if we want to change one student's address and the address exist in more than one table, then the DBMS allows you change all the entries of that student's data at one time. If by accident accident one entry is not changed then the data becomes inconsistent (mismatching). This is what DBMS helps prevent. Also DBMS prevents same entries for example if you have setup a primary key then whatever you enter in it the DBMS makes it unique for that record. That means you wont be able to use the same identification number for different students.
Answer:
To prevent mismatching and duplication of data records are more complete and consistent when, DBMS is used to maintain data. Consistency of data implies no mismatching or duplication
Explanation:
when a DBMS is used to make the data the records are more complete and consistent because if there will be mismatching or duplication of data the person will confused which is using Access so the records are more complete and consistent when A DBMS is used to maintain data
