A design elements overview
application design is composed of several different types of design elements,
each one with a different function over an application. In this section,
we discuss the design elements that are available on the Web with
Domino Designer Release 8.
is an element that displays a set of frames that enables
designers to improve the usage of the users' screen. A frame
a small portion of a frameset that is used to display a design component
in a specific space of the application screen. By using framesets, designers
can create relationships between frames, combining navigation, linking
and data display on a same screen. The frameset design element allows designers
with no experience on HTML to create Web site framesets in an intuitive
tool. For more information, refer to Frameset
Pages are the best design available in Domino Designer to display information
for the user. With pages, designers can store rich text data, including
images and formatted text, and some programmatic components, including
buttons and actions. In a Web environment, programmers can take advantage
of the available rich text converter, which translates the Notes design
entered on a body into HTML. For more information, refer to Page
Just like pages, forms enable designers to display information on a page.
Everything that can be done with a page can be done with a form. Between
forms and pages, forms allow the collection of data of the unique information
from the user. To achieve data storage, forms offers a variety of fields
of different data types, each of them representing a column in the Lotus
Notes database model. When working on the Web, Lotus Domino creates the
proper HTML tags for fields and forms on its pages automatically, enabling
programmers to code applications much faster. Using forms also enables
running several event driven computations. For more information, refer
Views are the most used way to allow users to navigate into applications'
data collected on forms. They are basically used to display a selection
of documents from a Lotus Notes database. Views can be sorted, customized
and searched. On the Web, views can be formatted in template forms to allow
user interaction, search and navigation over the database records. For
more information, refer to View
Folders are containers that store documents. From the design point of view,
folders are similar to views. The main difference between views and folders
is that views have a selection of documents, while a folder remains empty
until a set of records is moved to it. Folders can be used to display database
data on the Web just like views. For more information, refer to Folder
Agents are Lotus Notes programs that can run a variety of computations.
They run from several application-based events, from user triggered events
to scheduled tasks. Agents can do simple tasks, from moving database data,
to running complex computation like running Java programs. Agents can be
called on several background tasks on the Web, including on forms events
and using Domino URLs with arguments. For more information, refer to Agent
A Web service is a self-contained, self-describing, modular application,
based on XML, that can be published to and invoked from the Web. Lotus
Domino Web Services are based on the WSDL language and SOAP protocol W3C
standards. By using Web Services, programmers can modularize enterprise
services in a standardized programming model, reducing application maintenance
effort and improving reuse.
On Lotus Domino release 8, programmers can
also create Web Services consumers to use available Web Services implementations
from the Lotus Domino Designer IDE. For more information, refer to Web
service design elements.
Outlines are simpler to implement navigation on a Lotus Notes application.
By using an outline, designers can allow user to access key functionalities
from their applications on an intuitive navigation model. Outlines can
have diverse entries and can be embedded in pages and forms. Outlines can
be also placed in framesets, improving the usage of an application screen.
On the Web, outlines help programmers promote navigation and action invoking
without needing HTML experience. For more information, refer to [outlines].
You can designate many items, such as graphics, fields, subforms, and even
programs, as shared resources. Shared resources allow simple access to
a set of code used repeatedly over an application, enabling reuse
and reducing the application maintenance effort. In the following sections,
we discuss the shared resources that are available on a notes application.
Image resources are graphic files that
can be used across a Lotus Domino application. The use of image resources
helps application standardization and reduces the database file size by
preventing the usage of repeated images files across an application. Image
resources can be invoked on the Web by using embedding through Domino URLs.
For more information, refer to Image
resource design elements.
Shared fields have their properties defined
in an unique field design, and reused across the database in any form or
subform. The use of shared fields helps to reduce the effort on application
maintenance. Shared fields can be used in conjunction with a variety of
reserved fields on the Web to help Web-pages programming and look and feel,
tags definition and current session information
through CGI variables. For more information, refer to Shared
field design elements
Non-NSF file resources
Non-NSF file resources allow programmers to
host non-Notes binary files in an NSF database for any kind of usage. These
resources are also available on the Web through Domino URLs, by allowing
programmers to host Web components, such as animations and plug-ins on
a central repository, just like a common Web server file system. For more
information, refer to [Non-NSF file resources].
A subform is a collection of designs,
such as fields, graphics, buttons, and actions that a designer may reuse
in more than one form. They can be invoked programmatically depending on
a document or environment property. Subforms can be used on the Web to
hold different sections of a page, just like other server-side scripting
languages like PHP or Microsoft ASP includes. For more information, refer
A script library is a repository to
can also be accessed through Domino URLs, simplifying the access for cross-organizational
library design elements and LotusScript
library design elements.
Shared Java files
For big Java applets using various files,
it is most efficient to store some of the related files as shared resources
in the database. When setting up files as shared resources, all the applets
can use a single copy of a file, instead of each applet storing its own
copy. Therefore, in case of an update, only one file is updated. For more
information, refer to Applet
Shared actions can be used on forms, subforms,
pages, and folders of views that have common user activated tasks. On the
Web, shared actions can be displayed using HTML or Java applets. For more
information, refer to [shared actions].
Cascading style sheets
Cascading style sheets (CSS) can be hosted
on a Domino environment for Web pages design information. For more information,
refer to Styles
and CSS primer.
Composite application components
Composite applications are aggregations of multiple components brought
together for a business purpose. Composite applications can be used on
a Domino Web application to bring "portalization", and enabling
the use of "portlet" like components. For more information, refer
to [composite application components].
Navigators are graphical components that help users navigate through specific
parts of an application. Navigators are not a recommended design element
for Web applications, since they were surpassed by other components that
bring better and more efficient results. For more information, refer to
