- What's new in HCL Domino Designer 11 for developers?
  The following features are new for developers in HCL Domino® Designer 11.
- 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.

  - 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:
      - Database encryption
        Database encryption is designed to prevent unauthorized access to locally stored databases and is not intended as a replacement for field-level encryption. Database encryption provides an additional layer of security because ACL settings do not protect locally stored databases.
      - To encrypt a database
      - Encrypting documents and fields
        A document is considered to be encrypted if it is created from a form that contains one or more encrypted fields. Each encrypted field is linked to a key that encrypts the contents of the field. An encryption key can be secret -- that is, a key that you must send to users in order for them to decrypt a field -- or public -- that is, a key that is already in a user's ID file and in the user's Person document where it is publicly available.
      - Procedural overview: encrypting documents
      - Enabling encryption for a field
        You can enable encryption for more than one field in a form. The field can be any data type.
      - Creating secret encryption keys
      - Distributing secret encryption keys
      - Merging secret encryption keys
      - To create a field that maintains a list of secret encryption keys
      - Managing encrypted information
        As you consider what type of encryption you need in your application, keep the following in mind:
      - To encrypt all documents automatically
      - Using electronic signatures in Notes® applications
      - Attaching signatures to documents
  - 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.

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:

Messages sent to other users. Then an unauthorized user cannot read the message while it is in transit or in the recipient's mail file. You can also encrypt saved and incoming messages.
Network ports. Encrypting information sent between a Notes® workstation and a Domino® server, or between two Domino® servers, prevents unauthorized users from reading the data while it is in transit.
SSL transactions. Server administrators can use SSL to encrypt information sent between an Internet client, such as a Notes® client, and an Internet server, to prevent unauthorized users from reading the data while it is in transit.
Fields, documents, and databases. You can encrypt fields within a document, an entire document, and local databases. Then only the specified users can read the information.
