By being familiar with how a relational database operates, and by taking advantage of the database’s built-in controls, you can alleviate a lot of potential headaches down the road.
- [Narrator] Databases used to exist solely…in the world of the computer scientist,…and it often took years of study…in order to design and manage a well-constructed database.…But today, databases are much more accessible…to the average computer user.…To get the most out of any database…and to take advantage of their benefits,…one must still pay attention to some…basic design principles, though.…The database development life cycle provides…us with a series of steps that we should move through…when developing a database.…And I know what you're thinking,…that seems like a lot of work.…And I know that sometimes there's a desire…to shortcut the process and jump straight…into the relational database management system…and start building the end product.…
And I'll tell you right now,…that almost always ends in a disaster.…The process exists because there's a real need…to sit down and carefully think through…your data requirements upfront.…And to illustrate that point, I thought we could…take a look at some of the problems that can arise…
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.
