There s a lot going on in the diagram, so later I ll describe important parts of it with separate use cases and partial-wiring diagrams The shaded area enclosing the signals between NavigatorSearch and CoordinatorSearch represents a background operation NavigatorSearch runs searches in a background thread, because you don t want the UI to freeze up while a search is in progress The system requirements also specify that a search in progress must be interruptible using the Stop button Using a separate thread to run the search on makes it easy to stop the search at any time, without the need to constantly poll the user interface for stop commands CoordinatorSearch controls the threading, and there is no thread-related code anywhere in the system except in CoordinatorSearch.

Traditionally, DBAs had to contend with regular ORA_1555 (snapshot-too-old) errors because the rollback segments were being written over with new information too quickly for some transactions. When a DBA uses traditional rollback segments, he or she has the responsibility of monitoring the rollback segments for contention and may also need to change the number and size of the rollback segments. AUM eliminates most of the undo-block and consistent-read contention.

Traditional rollback segments would sometimes be slow to relinquish the space they occupied, even after their transactions completed. Undo segments use space much more efficiently by exchanging space dynamically with other segments. Oracle will create, bring online, and take offline the undo segments automatically as needed. When the undo segments are no longer necessary, Oracle will reclaim the space used by the segments. It is common practice for DBAs to assign a transaction to a specific rollback segment using the SET TRANSACTION command. AUM removes the need to do this manual assignment of rollback segments Oracle manages all undo space allocation automatically behind the scenes. Several of the Flashback recovery features, like Flashback Query, Flashback Versions Query, Flashback Transaction Query, and Flashback Table, require the use of undo data.

Before you embark on the normalization process, it s a good idea to understand the concept of functional dependence, which is defined as follows: Given a relation (table) R, a set of attributes, B, is functionally dependent on attribute A if at any given time each value of attribute A is associated with a given value of B. In simple terms, functional dependency is denoted symbolically as A B (meaning that entity A determines the value of entity B), and it turns out to be crucial in understanding the normalization process. Normalization is nothing more than the simplification of tables into progressively simpler forms to get rid of undesirable properties, such as data anomalies and data redundancy, without sacrificing any information in the process. E. F. Codd laid out the normalization requirements succinctly by requiring the elimination of nonsimple domains and then the removal of partial and indirect dependencies. As the tables are taken through simpler normal forms, the preceding problems are eliminated.

When the user clicks the Search button, NavigatorSearch fires a SearchRequested event to CoordinatorSearch, which spawns a background thread to run the search on By keeping all the threading logic in the Coordinator, you can keep the NavigatorSearch Worker relatively simple..

You can take a table through several levels of simplification, called the first normal form (1NF), second normal form (2NF), third normal form (3NF), Boyce-Codd normal form (BCNF), fourth normal form (4NF), and fifth normal form (5NF). Each successively higher stage of the normalization process eliminates a particular type of undesirable dependency that you saw earlier.

In this and the following sections, I ll show you a set of data that is non-normalized and then show you how you can make it conform to various normal forms. In the initial list of data shown in Table 2-1, each employee s information is accompanied by the skills that the employee has. Some employees may have a single skill, and some may have several. In order to answer a simple question, such as Does John Thomas have accounting skills you have to first find John Thomas s record and then scan the list of skills associated with that employee. Obviously, this is inefficient and leads to the maintenance of redundant data.
