  - Security in an application
    Domino® offers a multi-layered approach to security. Server administrators can secure databases, servers, and domains. Database designers and managers control the following:
    - The database access control list
    - Application design element security
      An application developer can restrict access to design elements within an application. Application design security takes effect when users gain access to an application.
    - Notes® and Domino® encryption
      Encryption is a digital security mechanism that protects data from unauthorized access. Encryption protects data from unauthorized access. Using Notes® and Domino®, you can encrypt:
  - Completing an application and managing design changes
    As you prepare to deploy an application, consider these finishing touches:
  - Deploying an application
    The tasks involved with application design, database design, database management, and DominoTMsystem administration may overlap, depending on the size of your organization and the structure of job responsibilities. In some organizations, an application developer may be responsible for both application and database design, while in others, a database manager may handle all database design and management tasks. In addition, database management overlaps with Domino® system administration.
  - Procedure for optimizing and troubleshooting databases
- 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
  Welcome to the LotusScript® Language section of Domino® Designer Help.
- LotusScript/COM/OLE Classes
- Java/CORBA Classes
  This section documents the Java/CORBA classes.
- Connectors
  Connectors provide native access to a wide variety of DBMS products, ODBC, the platform File system, Enterprise Resource Planning systems, and Transaction Processing systems.
- 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.

Security in an application

Domino® offers a multi-layered approach to security. Server administrators can secure databases, servers, and domains. Database designers and managers control the following:

Application Security
Use the database access control list (ACL) to restrict access that specific users and servers have to an application. You can also use the Advanced section of the ACL to further restrict application access for Web users.
Design element security
Use the database access control list in conjunction with access control fields to restrict access that specific users and servers have to an application. You can also use access lists and special fields to restrict access to specific design elements within an application.
Encryption and database signing
You can further ensure data privacy by encrypting a database with an ID so unauthorized users cannot access a locally stored copy of the database. You can also sign or encrypt mail messages users send and receive, and you can sign the database or template to protect design elements from manipulation from outside formulas.
