PowerBuilder is a development tool for building data-driven applications. To get started, you create a workspace, which organizes your project. Within the workspace, PowerBuilder Libraries (PBLs) store objects like windows, menus, and scripts. You can create a PBL by adding a new target to your workspace. Tabular Data Windows (TBT files) help display database records in a grid format, making it easy to manage and interact with data. PowerBuilder uses PowerScript, its object-oriented language, for handling events like button clicks. It’s a powerful tool for quickly creating database applications with a focus on efficiency and organization.
