The previous chapter discussed how to create tables and other structures to hold your data. Now it is time to fill the tables with data. This chapter covers how to insert, update, and delete table data. We also introduce ways to effect automatic data changes when certain events occur: triggers and rewrite rules. The chapter after this will finally explain how to extract your long-lost data back out of the database.
