Every database design project should start with a clear understanding of what the project's goals are. The focus should be on what the database needs to do, not how the database needs to do it.
- [Instructor] Every database design project…should start with a clear understanding…of what the goals of the project are.…The focus should be on what the database needs to do…at a very high level…and not how the database needs to do it.…To this end, we're going to start the design process…with a well thought through mission statement.…The mission statement will be the guidepost…that we can always refer back to…in order to make sure that the development process…is proceeding on course.…It can help prevent what's referred to as "scope creep,"…where new features and enhancements continually get added…to the project and the database never seems to get finished.…
The mission statement is developed in conjunction…with the initiator of the project.…Typically, this is the person that gave the green light…to proceed after the planning phase,…where the need for a new database was initially requested.…This could be a member of the management team,…or the head of the organization.…It should be as focused as possible when defining the goal…
Adam Wilbert covers the basics of relational database design, regardless of whether you use Access, FileMaker, Open Office, or SQL Server. Learn how to prevent data anomalies, gather requirements to plan your design, and develop a conceptual data model—translating your ideas into components like tables, relationships, queries, and views. Plus, learn about logical design considerations that can help you construct a database that is easy to maintain.
- Identify the three rules of relations.
- Summarize the four stages of developing a relational database.
- Describe a strategy one might use to ensure a database remains flexible in terms of the questions a user can ask.
- Explain how to avoid scope creep.
- Recall the characteristics of a Lookup Table.
- Recognize situations in which denormalization would be beneficial.
- Understand the types of relationships modeled by junction tables.
- Define referential integrity.
