Aboutsss Course:

This course introduces people to the principles and process of logical data modeling, Physical Data Modeling using ERWin Tool. The course details how to convert the business data requirements into a graphical representation. It teaches people how to analyze business requirements that should be incorporated into a logical data model and in Physical Data model in turn. In short, participants will learn proven, practical skills for analyzing and modeling data requirements, and make them ready to be transformed into a relational database and design multi Dimensional Database.

Curriculum

Data Modeling and Design Using Erwin

Data Modeling and Relational Database design using ERwin

Introduction to Logical Data Modeling

  • Definitions
  • Benefits of logical data modeling
  • Data modeling vs. physical database design
  • Roles involved in data modeling
  • Steps in the data modeling process
  • Example data model

Entities

  • Identifying entities
  • Validating entities

Documenting "instances" of entities
Distinguishing entities from attributes

  • Naming entities
  • Starting an Entity/Relationship (E/R) diagram
  • Workshop

Relationships

  • Identifying significant relationships
  • Determining the "cardinality" or "degree" of a relationship
  • One-to-One
  • One-to-Many
  • Many-to-Many
  • Determining whether a relationship is optional or mandatory
  • Giving a relationship a name
  • Documenting the relationships in the E/R diagram
  • Walking people through an E/R diagram
  • Workshop
  • Resolving Many-to-Many Relationships
  • Real-world examples of many-to-many relationships
  • Why many-to-many relationships are broken down into simpler relationships
  • Identifying "association" or "intersection" entities
  • Documenting the new relationships in the E/R diagram
  • Workshop

Attributes and Normalization

  • Defining and categorizing attributes
  • Domains and integrity rules
  • Unique identifiers/primary keys
  • Foreign keys
  • Occurrence population
  • Normalization: validating the placement of each attribute

Attribute does not repeat (first normal form)
Attribute is dependent on its entire UID (second normal form)
Attribute is dependent only on its UID (third normal form)

  • Workshop

Subtypes and Super-types

  • Identifying subtypes: real-world examples of subtypes and supertypes
  • Determining when entities are similar

UIDs
Attributes
One-to-one relationships

  • Creating subtypes and supertypes
  • "Type" entities
  • Using subtypes to apply fourth normal form
  • Establishing the relationships of the sub- and super-entities to other entities
  • Mutually exclusive vs. non-mutually exclusive subtypes
  • "Role" entities to handle complex subtypes
  • Workshop

Recursive Relationships

  • Real-world examples of recursive relationships
  • Discovering recursive relationships
  • Determining whether the relationships are optional or mandatory
  • Documenting the new relationships in the E/R diagram
  • Hierarchical vs. Network recursive relationships
  • "Structure" or "Bill of Materials" entities: fifth normal form
  • Workshop
