Can somebody help? Like, can someone answer these questions for me? I have an information systems and database topic test coming up in 2 days so I need to know this. And not being able to know how to answer these 2 questions is a bad start. >.<


1. Explain how QBE, SQL and DBMS are related. (Force yourself to write one succinct sentence)


2. How is a field named in SQL if there is more than one relation? Give an example.

One sentence makes it rather a superficial answer...

One way a database management system (DBMS) helps users access and manipulate data is by searching using different specialised languages, such as Structured Query Language (SQL), and constructing queries using query by example (QBE) which match certain criteria against a field.


The SELECT statement is used to query the database and retrieve selected data that matches the criteria FROM specified tables of data.
