Relational Database : A database Management System is a software application for managing the database in a well-organized form. It provides a systematic way to create, retrieve and update the database. In DBMS, the schema explains the logical structure of the data base system. It provides the capability to the user to self-analyze the database and perform the necessary operations. A relational database comprises of rectangular tables known as relations. Every row in relation is known as tuple. Each column in table is termed as field or attribute. It describes the characteristics of entity represented by corresponding tuple. Relational database design process: It is designed to meet requirements of particular application. There are no two databases that are alike. The design choice is based on user preference. The steps used in this process includes: Step 1 – Define the database purpose Step 2 – Gather data and organize in table Step 3 – Refine and normalize design, it includes adding columns, creating new relation and splitting large relation into smaller relations.

PLZ help with the following: IN SQL Let R (A, B, C) be a relation schema. What happens if we execute the following query? SELECT* FROM R WHERE A=D; Select one: a. We get an error. b. The query executes successfully but returns no tuples. c. The query returns all the tuples in R.

Report the eid of every employee who manages at least two different people. Use the usual technique of table renaming and self-join, except use the keywords CROSS JOIN to take the Cartesian product of the two tables: sales(eid, day, amount)employee(eid, name, salary, dept)manages(manager, junior)department(did, name, division)employee[dept] ⊆ department[did]manages[manager] ⊆ employee[eid]manages[junior] ⊆ employee[eid]sales[eid] ⊆ employee[eid] USE CROSS JOIN PLEASE! Only Cross Join is allowed. Do not use other SQL techniques please.
