In this chapter, we've introduced a lot of terms and concepts to explain the internal architecture of the Oracle RDBMS. Throughout the course of this book, we will continue to revisit these concepts and expand on them as we go, in an iterative fashion. We've examined the components of the Oracle instance, the background processes, and the memory caches. We've explored each of these components in greater detail, such as looking at each of the aspects of the caches. We've connected this to the other side of the Oracle RDBMS—the database. We've examined each of the core datafiles that make up the database. In the process, we've seen how both the instance and database work together to form the Oracle architecture. We've also examined Oracle RAC, an alternative to the single-instance architecture that offers scalability and high availability. In our next chapter, we'll learn more about the database side of the RDBMS; we'll learn to manage tablespaces and the data within them.
