PowerPivot for Excel CHAPTER 10 191
The Atom Data Feed Provider
Last, the add-in installs an Atom data feed provider to allow you to import data from Atom
data feeds into a PowerPivot workbook. A data feed provides data to a client application
on request. The structure remains the same each time you request data, but the data can
change between requests. Usually, you identify the online data source as a URL-addressable
HTTP endpoint. The online data source, or data service, responds to requests at this endpoint
by returning an atomsvs document that describes how to retrieve the data feed. When you
open an atomsvc document, the PowerPivot Atom data feed provider detects the le type
and prompts you to load data into PowerPivot. When you conrm the load operation, the
provider connects to the data service, which in turn encapsulates the data in XML by using
the Atom 1.0 format and sends the data to the provider.
Data Sources
Your rst step in the process of developing a PowerPivot workbook is to create data sources
and import data into the workbook. You can import data from a variety of external data
sources, including relational or multidimensional databases, text les, and Web services. You
can also import data by linking to tables in Excel, or simply by copying and pasting data. Each
data source that you add to the workbook becomes a separate table.
External Data
When your data comes from an external data source, you use the applicable button in the
Get External Data group of the ribbon in the PowerPivot window, as shown in Figure 10-2.
The button you choose launches the Table Import Wizard for the type of data that you are
importing.
