Visit   Implementing Object Caching with AOP    Last Update 2006/9/14 9:06
Category  Programming  arrow  Java  :  Database  :  Approaches, Process, Methods  arrow  Object Oriented Analysis and Design
Description
Object caching provides a mechanism to store frequently accessed data in memory, minimizing the calls to back-end database, and resulting in significant improvement in the application performance. By making caching an Aspect we get the flexibility of dynamically adding caching ability in a J2EE application for cached objects. We can also remove caching out of the application whenever it becomes a bottleneck in terms of memory usage. In this article, I will provide an example of object caching as an Aspect in J2EE applications and discuss the steps involved in injecting the caching functionality into a sample web application.

Visit   Integrate the RIA framework ZK with Informix    Last Update 2011/9/6 13:14
Category  Database  :  Programming  arrow  Tools  :  Programming  arrow  Platforms  arrow  AJAX
Description
This tutorial presents a real-world example that integrates IBM® Informix® and ZK, a rich Internet application (RIA) framework. Informix is a flagship IBM RDBMS product, while ZK is a Java-based web application framework supporting Ajax applications. This event-driven framework enables creation of rich user interfaces with minimal knowledge and use of JavaScript. ZK's unique server-centric approach enables synchronization of components and events across the client and server via the core engine.

Visit   Java and the Empowered Database    Last Update 2006/9/14 7:44
Category  Programming  arrow  Java  :  Database
Description
The connection between object-oriented systems and relational databases is commonly solved by employing a so-called O/R mapping (ORM) framework whose goal it is to map object-oriented models to entity relationship models which are used, often generated, in relational databases. An unwritten consensus in the industry is that the best approach in solving these problems is a process where the business requirements are modelled in the object domain and where the resulting object model is mapped via an O/R mapping framework into the relational database system. This article proposes a reversed approach where the modelling is done in the relational tier and as much business logic as possible is handled within the database by employing a set of stored procedures as the middle tier.

Visit   Java development 2.0: REST up with CouchDB and Groovy's RESTClient    Last Update 2009/12/10 13:10
Category  Database  :  Programming  arrow  Tools  :  Programming  arrow  Platforms  arrow  Services / Microservices  :  Programming  arrow  Groovy
Description
A burst of innovation in the open source world over the last few years has led to an increase in Java™ developer productivity. Freely available tools, frameworks, and solutions address once-common time sinks. A promising new entry on the scene is Apache CouchDB, hailed by some as the database for Web 2.0. The big picture of CouchDB is easy to grasp, and using it is as simple as using a Web browser. This Java development 2.0 column introduces CouchDB and shows you how Groovy's RESTClient can help you tap into its strengths.

Visit   Lightweight database federation in oil-and-gas production with SQL Relay    Last Update 2010/4/14 13:25
Category  Database  :  Programming  arrow  Tools
Description
Conflicting requirements, such as those related to security, performance, and economy, multiply the challenge of integration developments typical in programming in the oil-and-gas industry. One technique that can help ease the burden on slimmed-down development teams is to centralize database accesses through the open source SQL Relay product.

Visit   Many-to-Many Mapping without Hibernate XML    Last Update 2008/6/5 9:56
Category  Database  :  Programming  arrow  Tools  :  Programming  arrow  Groovy
Description
One pattern that shows up repeatedly is creating a Many-to-Many relationship using a mapping class. In Rails, the hasMany/through directive provides this functionality. Grails doesn't have an explicit hasMany/through statement like Rails. Rather, Many-to-Many relationships are created implicitly by GORM via your domain classes.

Visit   Mastering Grails: GORM: Funny name, serious technology    Last Update 2008/2/28 7:28
Category  Programming  arrow  Java  :  Database  :  Programming  arrow  Tools
Description
This article focuses on another area that Grails makes easy: persistence using the Grails Object Relational Mapping (GORM) API. I'll start by describing what an object-relational mapper (ORM) is and how to create a one-to-many relationship. Next, you'll learn about data validation, ensuring that your application isn't plagued with garbage in/garbage out syndrome. You'll see the Grails ORM domain-specific language (DSL) in action, which allows you to fine-tune how your POGOs (plain old Groovy objects) are persisted behind the scenes. Finally, you'll see how easy it is to swap out one relational database for another. Any database with a JDBC driver and a Hibernate dialect is fair game.

Visit   Mastering Grails: Grails and legacy databases    Last Update 2008/7/17 10:59
Category  Programming  arrow  Java  :  Database  :  Programming  arrow  Tools  :  Programming  arrow  Groovy
Description
In this Mastering Grails installment, Scott Davis explores the various ways that Grails can use database tables that don't conform to the Grails naming standard. If you have Java™ classes that already map to your legacy databases, Grails allows you to use them unchanged. You'll see examples that use Hibernate HBM files and Enterprise JavaBeans 3 annotations with legacy Java classes.
