It means atomicity must be present in relation. Consider the relation Employee as shown in Figure 6.8. It is not in first normal form because attribute Name is not atomic. So, divide it into two attributes First Name and Last Name Now, relation Employee is in 1NF. Anomalies in First Normal Form : First Normal form deals only with atomicity. Anomalies described earlier are also applicable here. Example. Given the relation PART (Part_ID, Descr, Price, Comp_ID, No) having the following dependencies Part_ID → Descr Part_ID → Price Part_ID, Comp_ID → No Determine the highest normal form of this relation. Sol. There exists multi-value attributes. The attributes Comp_ID and No are not determined by the primary key. Hence the relation is not in INF. 6.1- Features Of Relational Database Design DBMS | relational database design | database design    • 6.1- Features Of Relational Database Desig...   6.2- Anomalies in Relational Database Design | insertion anomaly | deletion & Updation anomaly    • 6.2- Anomalies in Relational Database Desi...   6.3- Normalization In DBMS | Functional Dependency And Normalization | Introduction To Normalization    • 6.3- Normalization In DBMS | Functional De...   6.4- What Is Functional Dependency In DBMS | Functional Dependency And Normalization | Dbms Course    • 6.4- What Is Functional Dependency In DBMS...   Notes Link: http://www.tutorialsspace.com/Downloa...
