  • Normalization
    Normalization Normalization is a process in which we refine the quality of the logical design. Some call it a form of evaluation or validation. Codd said normalization is a process of elimination, through which we represent the table in a preferred format. Normalization is also called “non-loss decomposition” because a table is broken into smaller components but no information is lost. Are We Normal? If all values in a table are single atomic values (this is first normal form, or 1NF) then our database is technically in “normal form” according to Codd—the “math” of set theory and predicate logic will work. However, we usually want to do more to get our DB into a preferred format. We will take our databases to at least 3rd normal form. Why Do We Normalize? 1. We want the design to be easy to understand, with clear meaning and attributes in logical groups. 2. We want to avoid anomalies (data errors created on insertion, deletion, or modification) Suppose we have the table Nurse (SSN, Name, Unit, Unit Phone) Insertion anomaly: You need to insert the unit phone number every time you enter a nurse. What if you have a new unit that does not have any assigned staff yet? You can’t create a record with a blank primary key, so you can’t just leave nurse SSN blank. You would have no place to record the unit phone number until after you hire at least 1 nurse. Deletion anomaly: If you delete the last nurse on the unit you no longer have a record of the unit phone number.

  • Database Normalization—Chapter Eight
    DATABASE NORMALIZATION—CHAPTER EIGHT Introduction Definitions Normal Forms First Normal Form (1NF) Second Normal Form (2NF) Third Normal Form (3NF) Boyce-Codd Normal Form (BCNF) Fourth and Fifth Normal Form (4NF and 5NF) Introduction Normalization is a formal database design process for grouping attributes together in a data relation. Normalization takes a “micro” view of database design while entity-relationship modeling takes a “macro view.” Normalization validates and improves the logical design of a data model. Essentially, normalization removes redundancy in a data model so that table data are easier to modify and so that unnecessary duplication of data is prevented. Definitions To fully understand normalization, relational database terminology must be defined. An attribute is a characteristic of something—for example, hair colour or a social insurance number. A tuple (or row) represents an entity and is composed of a set of attributes that defines an entity, such as a student. An entity is a particular kind of thing, again such as student. A relation or table is defined as a set of tuples (or rows), such as students. All rows in a relation must be distinct, meaning that no two rows can have the same combination of values for all of their attributes. A set of relations or tables related to each other constitutes a database. Because no two rows in a relation are distinct, as they contain different sets of attribute values, a superkey is defined as the set of all attributes in a relation. A candidate key is a minimal superkey, a smaller group of attributes that still uniquely identifies each row.

Case Studies(Refer text book) . 1. Schema Refinement: The Schema Refinement refers to refine the schema by using some technique. The best technique of schema refinement is decomposition. Normalisation or Schema Refinement is a technique of organizing the data in the database. It is a systematic approach of decomposing tables to eliminate data redundancy and undesirable characteristics like Insertion, Update and Deletion Anomalies. Redundancy refers to repetition of same data or duplicate copies of same data stored in different locations. Anomalies: Anomalies refers to the problems occurred after poorly planned and normalised databases where all the data is stored in one table which is sometimes called a flat file database. 1 DATA BASE MANAGEMENT SYSTEMS Anomalies or problems facing without normalization(problems due to redundancy) : Anomalies refers to the problems occurred after poorly planned and unnormalised databases where all the data is stored in one table which is sometimes called a flat file database. Let us consider such type of schema – Here all the data is stored in a single table which causes redundancy of data or say anomalies as SID and Sname are repeated once for same CID . Let us discuss anomalies one by one. Due to redundancy of data we may get the following problems, those are- 1.insertion anomalies : It may not be possible to store some information unless some other information is stored as well.
