PowerBuilder is an Application suite for building, maintaining, and developing high-value Windows applications from Sybase, a subsidiary of SAP. Powerbuilder simplifies prototyping and allows developers to create distributed applications for client/server, web, Win32, .NET, Java platforms, and Enterprise Edition (JEE) platforms.

PowerBuilder has a database that creates, edits and displays data. It can create object-oriented databases. It connects to other databases using Open Database Connection (ODBC). PowerBuilder provides native interfaces to support many large databases. PowerBuilder works extensively with companies in the financial, telecommunications, and construction industries as well as government agencies.

What is a PowerBuilder?

PowerBuilder is primarily focused on business applications, but some versions support applications that import .NET connections and database updates to mobile devices. The fourth generation is an object-oriented programming language that builds client-server applications and is a graphical user interface (GUI) that runs on Windows operating systems 32 and 64-3. in both bits.

The programming language PowerBuilder uses is called PowerScript, which is an object-oriented language. It helps in inheritance, polymorphism, and encapsulation. Programmers use a common code framework called the PowerBuilder Foundation Class (PFC) to inherit features from existing code. The PowerBuilder functions are compiled into P-code, which is then interpreted by the PowerBuilder function.

One of PowerBuilder’s most powerful features is the Data Section window, which allows you to enter, import, filter, and organize data. The data window uses a SQL graphical interface that supports federation, join, and subquery operations, allowing users to solve SQL queries. It generates data window updates in runtime SQL.

1. The first real power is something called ” DataWindow “. It is important that you understand how exactly to use this object and its associated control, the DataWindow header. If you are a good programmer. This includes PowerBuilder, you should never include SQL in a PowerBuilder application, as it is almost unnecessary. Data windows allow you to embed your SQL (and display format) into something that can be used throughout your application.
2. The PowerBuilder object is really focused – on inheritance, polymorphism, and encapsulation. With PowerBuilder, learn how to create and inherit your own classes, making your programs much more robust, and often easier to maintain.

What PowerBuilder has is that it can interface with most media. Unlike vendor-specific applications, PowerBuilder gives the user the freedom to work on any media and often bypass drivers. (For example, it’s much faster, more stable, and better than an ODBC connection.) For example, I built an application for an Access database, and I was able to deploy it to an Oracle database and I didn’t change it that could be removed. In 30 minutes. If I use standalone sql it will take days.

I’ve used a different environment that comes close to PowerBuilder, even on the client/server. VB is not object-oriented (although VB.NET now claims to be able to do this) and lacks the data analysis power that PowerBuilder offers. However, if you have used VB before you will be familiar with some of the control tools in PowerBuilder. Java and C++ may have a bit more flexibility, performance, and limitations, but the production and maintenance costs will be much higher than a 4th generation language like PowerBuilder.

What happens in the PowerBuilder application?

The PowerBuilder client application;

• A user profile is a list of windows, windows, and window controls that users use to navigate an application.

• Application Process Logic Event and function scripts in which you code business rules, validation rules, and other application processes. PowerBuilder allows user application logic to be coded as part of the user interface or in separate modules called custom class user objects.

What is a PowerBuilder component?

In a multi-tier application, the modules that make up the application processing logic (that you put on the server) are called entities. You can design, create, and deploy class user objects as application tools.

PowerBuilder applications are event-driven

In client applications, monitor what users do and what actions they take. For example, one or more events occur when the user presses a button, selects a menu item, or enters data in a text box. You write a script that describes the procedure to follow when the event is triggered.

Every window control and other application component you create with PowerBuilder has predefined events. For example, each button is associated with a clicking behavior and each textbox is associated with a changing event. Predefined cases are usually sufficient. But sometimes you can explain what happened yourself.

PowerBuilder language

You write PowerBuilder using the PowerBuilder language. Scripts consist of PowerScript commands, actions, and dialogs that are executed in response to an event.

For example, the printer can retrieve button-click event information and display it from the database; Changing Text Boxes Event Log can evaluate data and perform data management functions.

Other issues can also be created by running event logs. For example, clicking an event on a button may open another window, triggering an open event in that window.

PowerBuilder functions

PowerBuilder provides a useful list of applications that can run in different parts of your application. For example, there is a function that opens a window, a function that closes a window, a function that activates a key, a function that updates a database, and so on.

You can also create your own applications to define processes specific to your application.

Object-oriented programming with PowerBuilder

Each list or window you create with PowerBuilder is a self-contained module called an object. The basic building blocks of a PowerBuilder application are the objects you create. Each entity has unique features and attributes (properties, events, and actions). Using feature-oriented software, such as encapsulation, inheritance, and polymorphism, allows you to get the most out of each feature, giving your work reworkability, scalability, and strength.

PowerBuilder applications

Using PowerBuilder Enterprise Edition, you can configure applications and components for the .NET environment. This includes Web Forms applications that you can deploy to ASP.NET and Windows Forms applications that you can deploy using Smart Client as well as IIS applications. You can convert invisible custom class objects directly into .NET assemblies and also deploy them as .NET web applications.

See Deploying Tools and Objects in. NET.

Multitier applications

PowerBuilder allows you to create applications that run in a distributed computing environment. a multi-layered tool for you;

• Install business logic on servers like EAServer, JBoss, WebLogic, WebSphere, or COM+.
• A distributed application runs between the client and the server, reducing the workload of the client.
• Create scalable, easy-to-maintain software.

See Extended Application Processes for Functions.

Database connectivity

Organizational data stored in various databases in PowerBuilder can be easily accessed. Data is accessed through the PowerBuilder ODBC or JDBC interface, through a central data source such as a Sybase DirectConnect server, or through a direct or indirect connection to the database.

For more information, see Connect to your database.

Online Help and documentation

PowerBuilder’s online Help can be accessed using the Help button and menu items, or by selecting the F1 key from anywhere in PowerBuilder. Many places have features ranging from online help to HTML-formatted manuals. The manual is also available on the Sybase website.
