In this chapter, you learned how to build a real-world job application where employers can post their jobs and candidates can post their resumes. Object databases are quite useful in many situations, and as a developer there are quite a few situations when you need to deal with object databases as well as relational databases.
In the following chapter, we cover object and relational database mappings. You'll learn the basics of the object-mapped data model and how to create a simple video store application that allows users to load, create, and alter videos in the library as well as check in and out videos. You'll learn how to create mapped objects as well as workarounds for common pitfalls and quirks found in ADO.NET that can adversely affect your data model.
