- 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:
- Programming Overview and User Interface
  This section contains general guidelines and examples that show where to use Java, LotusScript, and the formula language.

  - Java™ Classes Coding Guidelines
  - Java™ Classes A-Z
    - Properties and methods with ECL security using Java™
      The following tables list the properties and methods affected by an execute control list (ECL). These properties cannot be accessed or set, and these methods do not execute on the workstation unless the marked ECL priveleges are granted to the signer of the formula.
    - Java™ constants
      The following sections provide contextual information for the constants used by the Java™ classes. Listed are the constant names, their integer values (in parentheses), and the properties and methods in which they are used.
    - Supporting components
      The following classes support the use of Java™ with Notes/Domino and the Domino® Objects:
    - ACL (Java™)
      Represents the access control list (ACL) of a database.
