Drools is an open source pure-Java implementation of a forward chaining rules engine. Drools can be used in a J2SE or J2EE application and allows you to express rules programatically or by building domain specific rule languages. Learn how Business Rules with Drools can make your Java applications more flexible and robust.

Software development is expensive, when business rules are hard-coded in your application's source code, changes and additions to those rules translate to wasted time and money. Good object-oriented, component-based approaches can alleviate the burden of keeping up with changes in the business world but they still require that expert knowledge of the changes be passed from the decision makers to the business analysts and finally to programmers that need to implement these changes. Business Rule Engines and Business Rule Languages are based on the basic premise of separation of concerns by empowering business domain experts to express the rules of business in a way that it is directly usable by applications. Drools is an open source pure-Java implementation of a forward chaining rules engine. Drools can be used in a J2SE or J2EE application and allows you to express rules programatically or by building domain specific rule languages. Learn how Business Rules with Drools can make your Java applications more flexible and robust.

In this session you'll learn some of the more advanced features of Drools; a pure-Java Rule Engine. This session will walk through the construction of an advanced Rules application covering such topics as:

• Fine control and monitoring of a Working Memory session
• Using Decision Tables
• Advanced Rule Language Features
• Building Domain Specific Languages
• Managing your Rules

Many of the problems that we deal with in enterprises around the world are not usually related to the particular infrastructure, framework or programming language chosen but rather to the evolution and maintenance of the business logic that governs those systems. All knowledge in an enterprise is handed down stream until it arrives at the programmer's door. With Rule based systems we can empower those with the business but there is still a fair amount of work to get the ideal architecture for a particular problem in place. In this session you'll learn some of the more advanced features of Drools; a pure-Java Rule Engine. This session will walk through the construction of an advanced Rules application covering such topics as:

• Fine control and monitoring of a Working Memory session
• Using Decision Tables

Hibernate is an open source Object-Relational Mapping Framework that mostly automates the tedious and time-consuming task of persisting Java objects to a relational database. Hibernate is quickly becoming the preferred way for enterprise developers to overcome the object-relational impedance mismatch and a good alternative to the coarse-grained Entity EJBs, low-level raw JDBC, and by-committee specifications like JDO. Learn what your choices in the ORM arena, what to look for in an ORM tool, and how to get started with Hibernate for your next J2SE or J2EE project.
