Application Management
Welcome to the Application Management section of Domino® Designer Help.
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 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.
Examples of access-controlled sections
The following examples illustrate different uses for access-controlled sections on forms.

  - 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.
      - Controlling access to a database during design
      - Restricting who can read or edit documents
      - Using a Readers field to restrict access to specific documents
        To limit access to specific documents created from a form, include a Readers field on the form. A Readers field explicitly lists the users who can read documents created from the form. Without Reader access to a document, a user cannot see the document in a view. For example, to limit access to an employee's personnel file to members of the Human Resources department, the employee, and the employee's manager, list those people in a Readers field.
      - Using an Authors field to restrict who can edit specific documents
        An Authors field works in conjunction with Author access in the database ACL. If you assign users Reader access in the ACL, they can read documents in the database but cannot edit their own documents. If you list those users in an Authors field, they can edit documents in the database.
      - To create Readers and Authors fields
      - Tracking who edits a document
      - Updating Readers and Authors fields
      - Setting up the Administration Process for databases
      - Creating controlled-access sections of forms
      - Examples of access-controlled sections
        The following examples illustrate different uses for access-controlled sections on forms.
      - Limiting Editor access to sections of forms
        In workflow applications, use sections to restrict who can edit or sign parts of a document. If a document requires more than one approval signature, you create a section on the form for each signature or group. For example, you might create a section specifically for the Purchasing group.
      - Creating read access lists to limit view and folder access
      - Creating write access lists to limit folder access
      - Access-controlled forms and documents
      - Creating public access pages, forms, subforms, outlines, views, agents, and style sheets
    - 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.

Examples of access-controlled sections

The following examples illustrate different uses for access-controlled sections on forms.

Computing an editors list from the access control list

The status section of a Business Card Request form has a controlled-access section whose formula allows only administrators (an access role in the ACL) to change the status of a request. The formula for the computed field is:

"[Business Card Administrators]"

Allowing the author to name section editors

An editable section of a Status Report form has a controlled-access section whose default value formula always allows the author to edit the status report. Users who have access to the document but are not the author can read the section but cannot edit it.

"@Author"

The author can choose Section - Define Editors to name additional editors for a particular status report.
