| | About this title |
This book shows a way forward in the development of secure enterprise software. The authors describe the business implications of Web 2.0---a set of techniques for user collaboration on the Web---and describe how the computer language EGL makes developers more productive, protects a company's investment in existing software, and facilitates use of Rich Internet Applications. In addition, the book provides an overview of Web security.
Enterprise Web 2.0 with EGL:
- Introduces a variety of concepts that are essential for understanding modern computing, including service-oriented architecture, cloud computing, and agile development
- Demonstrates how EGL handles widespread requirements such as service creation, database access, and reporting
- Outlines the runtime technologies supported by EGL, including Java Enterprise Edition, Windows, IBM i, UNIX, and the mainframe environments CICS, IMS, and z/OS batch
Enterprise Web 2.0 with EGL is useful for:
- Executives, managers, and architects who seek a creative, long-term response to the complexity of application development
- Traditional developers who need to access the latest runtime technologies
- Students of information technology
