In most enterprises, you often need to create critical workbooks at a
specific point in time, often on a regular schedule. For example, you
might create a secure workbook at an agreed-upon date and time every
fiscal quarter to confidently compare sales, inventories, revenues, and
profits between fiscal quarters. You do not want to be concerned that
the information in the workbook was changed by another user and that
unexpected differences in calculations and results complicate your
decision-making. This is sometimes called creating "one version fo the
truth," which means that when you compare the same workbook report with
other users, you can rely on a unique point it time (the date and time
that the workbook was created) to verify a consistent view of the data.
Connecting to Data in a Secure Way
For some Excel workbooks saved to Excel Services, all the data is stored in
the workbook. To update the data in Excel Services, the Excel workbook must be
saved again. For other workbooks, there are one or more connections to external
data sources, such as a database or OLAP cube. These connections contain
information about how to locate, log in, query, and access the external data
source. Although this connection information can be stored in the workbook,
often it is stored in an Office Data Connection (.odc) file, especially when the
data is shared by many users and the connection information needs to be updated.
The workbook author or an administrator can create the connection information by
using Excel 2007 to author the connection, and then to export the connection
information to an .odc file.
A Data Connection Library (DCL) is a special SharePoint document library that
can be defined as a trusted location library and that makes it easy to store,
secure, share, and manage .odc files. For example, an administrator may need to
move a database from a test server to a production server, or update a query
that accesses the data. By using one .odc file saved in a DCL, administration of
this connection information is much easier and the user's access to data is more
convenient because all workbooks use the same connection file and a refresh
operation, whether on the client or server computer, gets up-to-date changes to
that connection file. You can even set up Office SharePoint Server and a user's
client computer to automatically detect changes to the connection file and use
the most up-to-date version of that connection file.
Excel Services and Information Rights Management
Information Rights Management (IRM) is a way to provide privacy protection
for a Microsoft Office document and to ensure that sensitive information is only
viewed by appropriate people. For example, you may want to report quarterly
financial data only to select members of an executive committee one month before
the data becomes publicly available in a financial statement, so they have time
to prepare public relation responses and make appropriate business decisions.
Windows SharePoint Services Version 3.0 or later supports IRM on a document
library and all the documents in that library (whether or not those individual
documents are enabled with IRM). Once the document is uploaded to a document
library enabled with IRM, the document, in effect, becomes IRM-enabled.
Excel Services does not support loading Excel workbooks that have been
enabled with IRM, and it does not load an Excel workbook if it is enabled with
IRM or comes from a document library enabled with IRM. However, if you want to
take advantage of IRM, you can load an Excel workbook without IRM into Excel
Services, open the workbook as a snapshot, and then save the snapshot to a
document library that is enabled with IRM.
Using Excel Services with Other Business Intelligence Features
Excel Services is part of a collection of Office SharePoint Server features
collectively called Business Intelligence that an individual, a team, or an
enterprise can use. These features are designed to work together and support
quick, robust development of customized decision-making tools that can access a
variety of data sources -- often without the use of code.
The Report Center
The Report Center provides a central location for various Business
Intelligence data and objects, and contains special document libraries for
storing reports, lists, Web Parts, Web Part Page templates, and .odc files.
Within the Report Center, users can also search for items by using categories,
view a calendar of upcoming reports, and subscribe to reports that they find
relevant.
The KPI List Web Part
The KPI List Web Part gets data from SharePoint lists, Excel workbooks,
Microsoft SQL Server 2005 Analysis Services, or manual data entry, and then
displays a Key Performance Indicator (KPI), which is a visual cue that communicates the amount of progress made toward a
measurable goal. By using KPIs, you can easily visualize answers to the
following questions:
- What am I ahead or behind on?
- How far ahead or behind am I?
- What is the minimum I have completed?
Users can even drill down on the KPI items to see the detail behind the
visualization. For instance, if the status of a KPI is red (indicating a
problem), clicking on that KPI will automatically take the user that was
used to determine the current status of the KPI.
Each area of a business may choose to track different types of KPIs,
depending on the business goals that they are trying to achieve. For example, to
increase customer satisfaction, a call center might set a goal to answer a
specific number of calls within a shorter period of time. Or the sales department
might use KPIs to set performance goals, such as the number of new sales calls
made per month.
Filter Web Parts and Apply Filter Button
You can use the Filter Web Parts to display only the subset of data that you
are interested in viewing in other Web Parts and optionally the Apply Filter
Button to perform the filter operation. For example, a data source can contain a
five year history of multiple products for the entire country/region. By using
the Filter Web Parts and Apply Filter Button, you can simultaneously display
pertinent data for only one sales region, one product, or the current year in
several Excel Web Access Web Parts.
Office SharePoint Services has a number of different Filter Web Parts that
enable you to enter or to choose one or more values to change the contents of
one or more Web Parts on a page to display exactly the information that you
need.
