PowerBuilder can use to access server-side Java business logic. This owes much to the use of Java does not need to create applications, PowerBuilder will be able to quickly set up an appropriate application to access and run on J2EE-compliant application server on the EJB, such as Sybase EAServer, IBM WebSphere ™ Application Server, BEA WebLogic ™ Server and other application servers.

(9) PowerBuilder native interface

PowerBuilder Native Interface (PBNI) is a powerful PowerBuilder allows developers to add their own functions in the PowerBuilder. This is an API, in two ways to make contact with the outside world PowerBuilder.

The first approach, you can create DLLs in PowerBuilder as a type of local custom user object to provide one or more categories. This allows developers to write the expansion of the library, and then visit other as PowerBuilder in the PowerBuilder IDE in the visualization created and non-visual user object as access them. The second approach, PowerBuilder virtual machine (PBVM: PowerBuilder Virtual Machine) can be embedded in C + + or Java applications, or other be able to call C + +, can be used to call business logic written PowerScript applications.

(10) source code control

In order to source code control (SCC: Source Code Control) interface significantly increased, PowerBuilder 9 the introduction of the working space to initialize the implementation of threads, so that a large-scale application of the elimination of start-up delay. At the same time, the introduction of several amendments to a huge improvement - may decide to synchronize the state to support the expansion of the new integration. In addition, OrcaScript function can be used to create directly from the application of SCC warehouse PBL.

(11) OrcaScript

OrcaScript statement to allow the preparation of a batch in the PowerBuilder development environment outside the PowerBuilder application and document processing. OrcaScript able to control the source code to obtain the latest PowerScript object, object creation PBL to configure EAServer components, compile PowerBuilder executable file - all of which do not require the operator to interfere.

(12) PDF support

PowerBuilder provides two methods of data window will be saved as a PDF format of the object of statements. The default is the extraction method, which can store data of all types of window objects. At the same time, the window of data and that data can be saved as a document or string using XSL formatting objects (XSL-FO) or PDF format.

6 Sybase Open Company to expand the efforts of PowerBuilder

As early as 2002, Sybase Inc. announced that PowerBuilder and Microsoft NET framework for interoperability of the initial strategy.

Sybase Inc. has adopted a four-phase program to achieve PowerBuilder components and applications and those applications in the Microsoft.NET framework of interoperability.

PowerBuilder.NET the first phase of the strategy will be used to support the form of Web services, including the PowerBuilder 9.0 enhanced XML operations.

The second phase will include DataWindow.NET and DataStore.NET characteristics. The use of PowerBuilder in data access, DataWindow.NET and exclusive areas such as DataStore.NET to support patent applications from non-PowerBuilder access, and can be any. NET language used. Experienced PowerBuilder developer if you are using. NET, without having to learn new lengthy and complex ways to achieve integration DataWindow and DataStore.

In the third stage, the packaging business logic is not visual objects (NVO) will be moved to. NET architecture, PowerBuilder developers to make reasonable use of the current code, and moved to. NET environment. Similar development in PowerBuilder Integrated Development Environment (IDE) can still obtain a high productivity. They also can continue to create applications in PowerBuilder, the development of components, and be able to deploy these applications and components of the platform and the enterprise environment.

PowerBuilder's. NET support, including the final stage will be. NET framework into the components in the PowerBuilder IDE. This stage will change the appearance of PowerBuilder itself in order to make it look like in the. NET to create the same user interface. It also enables developers to call. NET components of the system, so that they can create in PowerBuilder-based. NET's object.

With PowerBuilder, application developers can choose their development platform required and the environment, including Windows DNA,. NET framework, Web and J2EE platform. It continues to simplify the structure of software development, the complexity of protocols and standards, enabling developers to focus on the preparation of software applications to solve complex business needs. Standards for emerging trends and development, PowerBuilder developers can choose the direction of the company to respond immediately, in order to add value to existing products.

Sybase Expands PowerBuilder effort to open them PowerBuilder9.0 performance has been perfect.

7 Concluding Remarks

Sybase launched the company in order to PowerBuilder9.0, has done a very meticulous preparations. I now use is a PowerBuilder9.0 beta4 version. To the introduction of a product, even released a beta version of the four, so that the work detailed in Sybase's history, is unprecedented, which can also be seen in the company's carefully Sybase. In the use of four versions of the process of beta, I found that each version has greatly improved, whether the introduction of new technologies, or rule out the possibility of error. It can be anticipated, PowerBuilder9.0 will not ensure that the majority of developers pb disappointing.

PowerBuilder9.0 in the process of learning to use new technology is easier to grasp the concept, but remember not to hurry, too much the overall situation, as it has each of the technologies needed for a long time to master; and only skilled mastered in order to develop a practical procedure. Otherwise, the door will always be around.

Look forward to PowerBuider9.0 issued as soon as possible!
