  8. EVALUATION of database normalization • Normal form - property relations in the relational data model, which characterizes it in terms of redundancy, which could potentially lead to erroneous results logically sampling or data change • Each tuple contains only one value for each attribute • All non-key attributes of all relations functionally dependent on the entire primary composite key • All depending on non-key attributes from key - direct (without transitivity)

  9. CONCLUSION • All necessary actions on the database were placed in the procedure • Were implemented triggers Jobs • Were tested

  10. List of references • Viejra R. Programming of databases MS SQL Server 2005 for professionals • YP Parfenov. Lectures on discipline, industrial DBMS. Part 1: MS SQL SERVER
