Data List Handler: A Pattern for Large Search Result Sets

This article describes a J2EE design pattern, the DataListHandler, that represents a substantial improvement over traditional methods for efficiently processing Internet searches and quickly displaying the results to the user. The DataListHandler design pattern addresses the problem of processing Internet search queries that return large result sets in an efficient manner.

These two chapters have been excerpted from Martin Fowler's 'Patterns of Enterprise Application Architecture'. The chapter on Domain Model Patterns looks at the Transaction Script, Domain Model, Table Module, and Service Layer patterns. The Distribution Patterns chapter looks at the Remote Facade, and the Data Transfer Object patterns. For each pattern, the chapters explain how the pattern works, when it should be used, and provide examples of their usage through sample problems and code examples.
