These three items are intertwined, and their goal is to make the index leaf blocks (the blocks that hold the actual index data) able to efficiently store data. An index is typically on a subset of columns. You will generally find many more times the number of row entries on an index block than you would on a heap table block. An index counts on being able to get many rows per block. Oracle would spend large amounts of time maintaining an index otherwise, as each INSERT or UPDATE would probably cause an index block to split in order to accommodate the new data. The OVERFLOW clause allows you to set up another segment (making an IOT a multisegment object, much like having a CLOB column does) where the row data for the IOT can overflow onto when it gets too large.

One thing that iBATIS does not currently implement is any sort of record locking to manage concurrent modifications to the same data. You can use one of several techniques to handle concurrent updates, such as using a timestamp or version number on rows in the database. For example, if you have an account table defined thusly:

CslaDataSourceView doesn t actually do much work. Rather, it calls methods on CslaDataSource to have it raise the four data access methods. The event handlers in the page then do the real work. For instance, here s the ExecuteInsert() method: protected override int ExecuteInsert( IDictionary values) { // tell the page to insert the object InsertObjectArgs args = new InsertObjectArgs(values); _owner.OnInsertObject(args); return args.RowsAffected; } An instance of InsertObjectArgs is created and initialized with the values list. This is a list of name/value pairs for all the data elements from the web page (provided by ASP.NET), which presumably correspond to properties on the business object. Then the OnInsertObject() method on CslaDataSource is called. That method simply raises the InsertObject method so the web form can handle the event to create a new business object and insert it into the database.

recommend it. When an add closure method is called, it doesn t know it s being called because of an add element operation. To have the closure functor know which operation is currently underway, a direction parameter would have to be added to the closure functor delegate. And that is a very bad idea, because it locks the delegate into certain operations. Following is an example of two closure functors implementing the add and remove element methods: public class TicketsBuilder { private class StatisticsCounter { private double _runningTotal; public StatisticsCounter() { _runningTotal = 0.0; } public void ClosureAddMethod( Ticket ticket) { _runningTotal += ticket.Price; } public void ClosureRemoveMethod( Ticket ticket) { _runningTotal -= ticket.Price; } } public static IList<Ticket> CreateCollection() { StatisticsCounter cls = new StatisticsCounter(); IList<Ticket> parent = new ClosureAddProxy< Ticket>( new List< Ticket>(), new DelegateClosure< Ticket>( cls.ClosureAddMethod)); return new ClosureRemoveProxy<Ticket>( parent, new DelegateClosure< Ticket>( cls.ClosureRemoveMethod)); } } In this modified implementation of TicketsBuilder, StatisticsCounter has two closure methods: ClosureAddMethod and ClosureRemoveMethod. The method ClosureAddMethod increments the ticket sales, and the method ClosureRemoveMethod decrements ticket sales. The method CreateCollection is modified to create two closure proxies: ClosureAddProxy and ClosureRemoveProxy. The appropriate closure method is associated to each proxy.

During implementation, the bean provider may mark this method (either on the business interface or the bean class) as @Asynchronous, wrapping the real return value in a convenience implementation of java.util.concurrent.Future called javax.ejb.AsyncResult:
