- 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.
- Formula Language
  This section documents the formula language.
- LotusScript® Language

- Javadoc™ for Domino® Designer related APIs
  As part of providing additional Java™ reference documentation, Domino® Designer ships with a help plugin that contains Javadoc™ for additional Domino Designer related APIs.

Database comparison tool

A new application template, CompareDBs Reports (comparedbs.ntf), installed on the Domino 12.0.1 server, can be used to compare two database designs and/or document contents or to analyze the design of one database.

Database comparison You can compare the design of two Notes databases or templates and generate a report that is saved in the database. Some of the options include the ability to:

Exclude documents from the comparison.
Integrate the reports that are generated with source control applications such as Git or Jira.
Use a diff tool of your choice rather than the built-in tabular report that shows differences between source and target.

Database design synopsis You can use the tool to generate a design synopsis of a database that is exported to another database. The target database contains documents describing each design element.

A second template. designsynopsis.ntf, is used to organize and display the design synopsis output as a searchable Notes application.

For complete information on all options and how to get started, use the template to create a new Notes application. (It's an advanced template). Then open the application and select Help > > About This Application and Help > > Using This Application .
