Chapter 4. Establishing Relationships > Test Data and Conclusion

Test Data and Conclusion

In Chapters 2, 3, and this chapter, you learned some of the principles of database design. The purpose was to teach you basic relational database principles and give you an overall sense of database design. But please remember that, in my attempt to make a coherent presentation of reasonable length, I've left out important steps in creating a real-world database.

For example, I've mentioned nothing about testing your database. You will want to use test data to be sure your database can generate the required queries, forms, and reports that meet your mission objectives. You will want to use both “good” test data and “bad” test data. Good test data—data that is accurate and meets data integrity standards—will show you whether you can enter the data you need and output it in the form of reports. Bad test data is data that violates the rules. You will want to make sure you cannot enter bad data into your database.
