HCL Domino Designer Basic User Guide and Reference
This guide provides information on using HCL Domino Designer and programming language reference information.
- 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.
- Application Design
  Welcome to the Application Design section of Domino® Designer Help.
- Application Management
  Welcome to the Application Management section of Domino® Designer Help.
- 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.
  - Connectors and Connectivity Guide
  - LSX for Connectors
    LotusScript® Extensions for Connectors (LC LSX) enhances the power of Notes® by extending its scripting to data outside of Notes through the use of Connectors. The programming model is independent of the individual connector. This eliminates the need to learn each individual system, while at the same time allowing experienced users to access the individual features of a specific system.
  - Accessing external databases through LS:DO
    Developers are advised not to use LS:DO. Developers should use the Connector LSX for (LCLSX) when accessing external data sources.
    - Setting up LS:DO
      Setting up LS:DO requires several steps, in which you install any needed software, register your data sources, and then create your script. Review the following sections as you set up LS:DO for your application:
    - Using LS:DO
      Once you have set up LS:DO and your script, you are ready to access your external databases. With LS:DO, you can:
    - Tips and techniques
      This section presents specialized topics concerned with enhancing your LS:DO application:
    - ODBCConnection (LotusScript)
      Represents the ODBC Data Access features for connecting to a data source.
    - ODBCQuery (LotusScript)
      Represents the ODBC data access features for defining an SQL statement.
    - ODBCResultSet (LotusScript)
      Represents the ODBC data access features for performing operations on a result set.
- 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.

Accessing external databases through LS:DO

Developers are advised not to use LS:DO. Developers should use the Connector LSX for (LCLSX) when accessing external data sources.

You can programmatically access external databases from Domino using the LotusScript Data Object (LS:DO). LS:DO is a LotusScript extension library that provides classes for working with Open Database Connectivity (ODBC) in an object-oriented, event-driven programming environment. LS:DO supports the OBDC Version 2.0 standard on multiple platforms, including Windows and AIX. The LS:DO is available on both the Notes client and the Domino server. It works in both single- and multi-thread environments.

LS:DO is a set of three LotusScript classes, which come equipped with a powerful set of properties and methods, as well as full SQL capabilities:

You can use the properties and methods in these classes to access an external database, run an SQL query, store the returned data in a result set, and then work with that result set. You can optionally send updated information back to the source database.

Working with LS:DO

With LS:DO, you can write a LotusScript program to perform the following actions:

Look up or retrieve data stored in external databases
Validate user-entered data enter against data store in external databases
Review data retrieved from external databases
Update data in external databases, either immediately or at scheduled intervals

LS:DO is especially useful for data access based on LotusScript events in Notes, such as clicking a button, exiting a field, or opening a document.

LS:DO works best for these types of operations:

Handling low volumes of data transfers
You can use LS:DO for high volume transfers, but its performance could be significantly affected.
Reading and writing data in the same program
LS:DO implements several properties and methods for retrieving, updating, and storing data.
Real-time data handling
LS:DO real-time data access is the best choice for optimizing data entry (for example, looking up data or validating user entries) and providing data access to mobile Notes users.
