Core Database Principles
When embarking on any new project or learning experience, it is essential that you have a strong foundation of understanding constructed from key concepts and parameters. As you begin your work with databases and database design, you should develop a firm understanding of key concepts and parameters that are critical to the foundation of all database design.
In this Discussion, you examine these key fundamental principles of database design.
- Review the information in this week’s Learning Resources concerning relational and entity relational databases. Focus on how the two are interconnected.
- Review information concerning cardinalities and consider what they are, how they are developed, and their role in database design.
- Review information concerning business rules, what they represent, and how they are reflected in the entity relationship diagrams.
- Review the conceptual model (Figure Q4.5) on page 150 of your text, Coronel, C. & Morris, S. (2015). Database systems: Design, implementation, and management (11th ed.). Stamford, CT: Cengage Learning. Think of a similar example of how each of these concepts would be reflected in a database design for your own organization.Post by tomorrow 6/28/2016 550 words in APA format with 3 references 1) A brief analysis of the connection between entity relational modeling and relational databases. 2) Discuss a brief example of a conceptual model that could be used in your own organization and list at least one business rule and two cardinalities that apply to that model.Required Resources

- Chapter 2, “Creating Databases and Simple Tables” (pp. 53–90)
In this chapter, the authors demonstrate how to create databases both from templates and manually, how to construct a table structure, and how to define the relationship between tables.
- Chapter 3, “Create Simple Forms” (pp. 91–114)
The focus of this chapter is creating forms, which enables standardized data to be entered into a database. The authors demonstrate how to create, format and customize the layout of forms.
- Chapter 4, “Display Data” (pp. 115–134)
This chapter concentrates on sorting and filtering information within a database in order to locate and display desired information. It begins with simple sorts and progresses through displaying information that matches specific, multiple criteria.
