PB and Easerver to build multiple application architectures

PowerBuilder is widely used as a development tool in C/s applications and is a recognized and efficient graphical 4GL tool. Easerver is an enterprise application server that integrates dynamic page publishing and transactional processing in one body. The combination of the two can constitute a multi-tier application development and submission environment, developers can not leave this integrated development environment for application development, debugging, submission and operation. An important feature of PowerBuilder is the provision of data window (DataWindow) technology. The Data window is an abstraction of the definition and development of the database connection process (see the previous period) to build the core components of e-business: Sybaseeaserver ", and provides developers with data templates and report templates, through which developers can implement data interaction with the database.
Easerver includes dynamic page Server PowerDynamo and transaction processing server jaguarcts, the combination of which makes easerver a dynamic Web page and processing e-commerce application server, supporting a variety of component types, such as COM, CORBA, JAVABEAN/EJB and Powerpuilder. One of its more notable features is its support for XML and Java EE.

The combination of PowerBuilder and easerver enables enterprises to achieve success in the following areas:

Upgrade from client/server to distributed application.

E-commerce applications for web and Internet development.

Support the foundation of the Construction Enterprise Portal.

Sybasepowerbuilder has a large number of loyal customer base. PowerBuilder previously used to build a client/server application. Sybase continues to enhance powerbuilder and other development tool products to meet customer and market needs. Sybase continues to commit itself to releasing its products to enable the enterprise to develop today's distributed applications and to meet the diversity of evolving structures and delivery methodologies.

Old customers can continue to use the technology and knowledge they have, and version 7 gradually adds new expertise, such as Java and Cobra. They can continue to work in powerbuilder environments and gradually expand into new areas as demand or interest grows. With Easerver, language is a major implementation option, and different component models can interoperate and be implemented in a single transaction. Therefore, for a job you can use the appropriate component model to give users greater flexibility.

Through Easerver, old customers get a powerful application server that can start Web and Internet design from scratch. By bundling a Web server and a component Transaction Server, Easerver provides the functionality needed to easily submit web-centric analysis and transactional applications. Users can also develop, debug, and submit functionality directly from PowerBuilder7.0 or PowerJ3.0 these environments that are more familiar to many developers. By using application integrators to help companies bridge their existing systems, users can expand on their existing systems and take on smaller risks as they enter the new technology field.

Sybase provides an important solution that includes the intrinsic level of indirection and abstraction within its products, with the core of Easerver support for all current leading component models, including EJB, COM, CORBA, JavaBean, and PowerBuilder. Sybase also provides a sophisticated conceptual development and submission structure for multi-tier environments, as shown in Figure 1. Easerver is based on its reliance and support for Java, IIOP, COM, CORBA, ODBC, and JDBC, providing high levels of flexibility and interoperability, which allows enterprises to connect or implement a variety of application systems. More importantly, because it is a standards-based base component, it is easy to connect to the existing infrastructure components of the enterprise. New users can benefit from a flexible and interoperable structure supported by a set of robust features.

At present, enterprises need the ability to develop and submit in a variety of environments. Therefore, a product is simply a web, distributed, or client/server environment that does not meet the requirements. Businesses need products that can handle all of these customer environments. Sybase understands this and launches the development and submission environment that meets all of these requirements. Designed to support a variety of environments, this is an advantage in today's marketplace, where users can develop and submit customer/server, distribution, or e-business applications in a wizard-friendly environment and make work very efficient and convenient. Easerver integrates the page server with the Transaction Server and integrates development, submission, and transaction processing. The component model used is transparent to the customer and to all supported client access types.

The advantage of PowerBuilder is that both novice and professional developers can work at their appropriate level. For new developers, PowerBuilder can accomplish many tasks through wizards, while for professional developers it allows them to operate independently. And, through PowerBuilder and Easerver,sybase, it provides a quick and easy way to migrate from client/server applications to Web and distributed applications. This full-featured application server and integrated application development environment has some features that can be smoothly converted to the distribution and e-business applications that will dominate the market.

Sybase enhances the functionality of PowerBuilder, enabling it to support web-based and distributed application development without neglecting the needs of traditional customers. Existing customers can continue to use PowerBuilder and have access to the more advanced features they need. Because PowerBuilder can automatically establish CORBA, COM, and remote PowerBuilder objects that are transparently interoperable with Java, Sybase avoids the problems associated with selecting a component model. The new wizards make it effortless for developers to build projects, apply shells, or customize to-do lists that connect to a specified task pipeline, and accelerate the development process by providing a useful abstraction level. New data windows Take advantage of existing powerful features and extend it to the web. Seamless support for PowerBuilder and Java benefits all customers.

Sybase also integrates PowerDynamo and jaguarcts into Easerver, which provides the main data-centric and process-centric services for submitting complex distributed applications. The independence of the Easerver component model makes it free from current controversies and provides a set of methods to handle any unpredictable events, functionally, easerver can be compared to all currently competitive application servers and beyond many other application servers in transaction modeling and management.

In short, the combination of PowerBuilder and Easerver establishes a strategic foundation and rich development and delivery environment for multi-tier applications, enabling developers, especially PowerBuilder, to build new e-business applications in a powerful and sophisticated environment.
