In this chapter, you will learn about
• Record types
• Nested records
• Collections of records
Chapter 11, “Introduction to Cursors,” introduced the concept of a record type. You have learned that a record is a composite data structure that allows you to combine various yet related data into a logical unit. You have also learned that PL/SQL supports three kinds of record types: table-based, cursor-based, and user-defined. In this chapter, you will revisit table-based and cursor-based record types and learn about user-defined record types. In addition, you will learn about records that contain collections and other records (called nested records) and collections of records.
