13.4 End-User Interaction
OracleAS Portal is designed to present
information to end users. Although an administrator controls the
basic creation and deployment of an OracleAS Portal site, end users
can also take advantage of OracleAS Portal to customize their user
experience, to search for information, or even to add content to an
existing site.
13.4.1 Customization
End users have a habit of wanting things shown
to them in a particular manner, and not all users in a community
agree on what this exact manner should be. OracleAS Portal can help
solve this problem by enabling end users to customize many aspects of
their OracleAS Portal interaction.You can grant the user the ability to customize the appearance of any
of his pages. Customization can cover a wide range of possibilities,
from setting the home page to changing the style of a page or page
group, to actually moving, adding, or deleting portlets from a
region. You can limit the degree of customization that any particular
user has, as well as lock down any region in a page to prevent user
customization of the content of the region.
13.4.2 Working with Content
OracleAS Portal was designed to be user friendly,
from the way it displays information to the way it implements
wizard-driven interfaces for developing some types of portlets.
Individual end users can also work within the framework of an
OracleAS Portal site to directly interact with content items.With proper permissions, an end user can manipulate the items in a
region. A user can add items to a page. An item can be text, a link
to a file, or a link to another source of information on the Web. An
administrator can specify a limit to the total amount of space
allotted to store items for a particular page group.Of course, not all users should be allowed to add items, willy-nilly,
to managed OracleAS Portal sites. To ensure that added content is
appropriate and relevant, a user can be given the privilege of adding
content only with approval. Content approval can be specified for an
individual page or for an entire page group.The approval can be a simple sign-off from another user or an entire
approval process involving many different users. When a user creates
a content item, she is automatically informed of the progress of the
item through the approval process, as well as whether the item has
been approved or rejected at each step.End users can also move items from one page or region to another or
rearrange the order of items within a region. Users can also delete
items with proper permissions. For existing items, a user can change
the item's category, add or delete an item from a
perspective, or add or delete search keywords for the item.OracleAS Portal also enables users to "check
out" a piece of content. If checkin/checkout is
enabled for an item, this ability can be downloaded by only one user
at any given time. OracleAS Portal can implement version control on
items, in which older versions of edited items can be saved and
retrieved.There may be times when a user will want to know if a particular page
gets new content items. You can set up a page so that a user with the
proper privileges can subscribe to the page and be automatically
notified when the contents of the page change. The notifications come
to the user via a built-in notification portlet.OracleAS Portal supports the use of Web-Distributed Authoring and
Versioning (WebDAV) clients to edit content accessed through OracleAS
Portal. WebDAV allows users to view OracleAS Portal as a web folder
within Windows Explorer. This displays OracleAS Portal and portal
pages in the same manner as desktop file explorers. Pages are
rendered as folders and items as files. Via this interface, users can
seamlessly interact between OracleAS Portal and their file system by
dragging and dropping content, files, and folders.OracleAS Portal essentially supports WebDAV in parallel with its
built-in features for content manipulation, and there are some
restrictions on the types of pages and content that can be used.
13.4.3 Searching
The
overall purpose of any OracleAS Portal site
is to centralize the display of information. As we suggested earlier,
all this aggregation of content can lead to information overload, as
a result of the sheer volume of information. OracleAS Portal includes
the classification schemes mentioned earlier, but also has a built-in
search capability to help users find the information they need
quickly.An OracleAS Portal user can search through an OracleAS Portal site to
find specific content. A search can look through items, pages,
categories, and perspectives for a specific word or words.
|
categories, perspectives, or item types, among other selection
criteria. This basic search capability can be accessed through a
built-in Search portlet or through a built-in Search box object built
into a page. You can perform more complex searches with the built-in
Advanced Search portlet. You can also limit the results the Advanced
Search portlet can return for users.A user can save a search, which allows her to repeat it without
having to reenter all the search criteria. A built-in portlet
provides access to saved searches.13.4.3.1 Oracle Text
You can enable Oracle Text for an OracleAS Portal site,
and doing enables you to offer significantly more sophisticated
searches. With the added capabilities of Oracle Text, a search can
automatically look for related words or use functionality such as the
nearness of words to each other, or the sound of the words (known as
soundex).13.4.3.2 Oracle UltraSearch
Oracle Application Server also comes with a component called
UltraSearch, an
extensible search engine that uses a crawler to index documents. The
documents are indexed from within their own repositories. The crawled
information can build indexes that stay within an Oracle
database.
