HCL Domino Designer Basic User Guide and Reference
This guide provides information on using HCL Domino Designer and programming language reference information.
- What's new in HCL Domino Designer 12?
  The following features are new for developers in HCL Domino® Designer 12.
- Accessibility and keyboard shortcuts
  Accessibility features assist users who have a disability, such as restricted mobility or limited vision, to use information technology content successfully.
- Application Design
  Welcome to the Application Design section of Domino® Designer Help.
- Application Management
  Welcome to the Application Management section of Domino® Designer Help.
- Domino® Query Language
  Domino® Query Language (DQL) is a facility running on a Domino server that provides a terse, shorthand syntax for finding documents. It supports a wide variety and complexity of search terms. It leverages existing design elements, avoiding the need to write detailed code to access them. DQL consolidates all methods in Domino for searching document contents.
- Composite Applications - Design and Management
  Composite applications are a key element in a service-oriented architecture (SOA) and contextual collaboration strategy. The ability to create and edit composite applications lets you easily integrate different types of components and technologies.
- DB2® Access views
  Domino® Designer includes two types of design elements to assist you in managing data contained in DB2® enabled Notes® databases:
