Validating constraints and oracle
Not only will you learn how to create heap tables, you will also learn the practical management skills you will need for day to day table management tasks such as managing concurrency with INITRANS and MAXTRANS, moving tables, using DBMS_STATS to collect statistics for the cost based optimizer, increasing performance by turning off redo logging, compressing tables and simple techniques for measuring DML performance. We will learn what they are, what makes them work (organization) and many other things that will let you put them to good use, including turning off redo logging when creating indexes to increase performance, collecting statistics with DBMS_STATS, making intelligent decisions on what columns should be indexed, when and how to create multi-column (composite) indexes, using index compression and when and where to create indexes.This lesson will teach you about Oracle table constraints.
