ASSIGNMENT 1 Define the schema for the following databases with specific data type and constraints, the table name and its fields name are to be taken from database description which are given below : A database is being constructed for storing sales information system. A product can be described with a unique product number, product name, selling price, manufacturer name. The product can sale to a particular client and each client have it own unique client number, client name, client addresses, city, pin code, state and total balance to be required to paid. Each client order to buy product from the salesman. In the order, it has unique sales order number, sales order date, client number, salesman number (unique), billed whole payment by the party or not and its delivery date. The salesman have the name, addresses, city, pin code, state, salary of the sales man, delivery date, total quantity ordered, product rate. Q.1.1.

Q1. What is SQL? Ans: Structured Query Language 2. What is database? A database is a logically coherent collection of data with some inherent meaning, representing some aspect of real world and which is designed, built and populated with data for a specific purpose. 3. What is DBMS? It is a collection of programs that enables user to create and maintain a database. In other words it is general-purpose software that provides the users with the processes of defining , constructing and manipulating the database for various applications. 4. What is a Database system? The database and DBMS software together is called as Database system. 5. Advantages of DBMS? Ø   Redundancy is controlled. Ø   Unauthorised access is restricted. Ø   Providing multiple user interfaces. Ø   Enforcing integrity constraints. Ø   Providing backup and recovery. 6. Disadvantage in File Processing System? Ø   Data redundancy & inconsistency. ...
