A lot of IT professionals have a good working knowledge of SQL yet lack the foundational knowledge of relational database design. Learning database design and the relational model will put you ahead of the game. This course covers all the essential aspects of relational database design with practical demos given in SQL Server. You will learn how to spot un-normalized data structures and how to correct them. You will learn all about the process of data normalization and why it is important. This includes the various normal forms such as Boyce-Codd normal form and fourth normal form. This course also covers tips on how to identify relationships between entities and how to correctly model them in a relational database.
You will be able to understand advanced database design concepts with the aid of intuitive diagrams and practical examples. You will learn how to identify functional dependencies and transitive dependencies in your data. You will learn the different types of keys and when to use them. In addition, you will learn the different types of relationships such as one-to-one, one-to-many, many-to-many, and self-referencing relationships. More importantly, the end of the course you will know how to enforce these relationships by using integrity constraints.
Note that you will need either a Windows or Linux computer to install SQLServer.
