Sharepoint Webpart Concepts

In order to create WSS-style Web Parts, you must have a dependency on the Microsoft.SharePoint.dll and you must inherit from the WebPart base class in the Microsoft.SharePoint.WebPartPages namespace.

In order to create ASP.NET-style Web Parts, you have a dependency on System.Web.dll and inherit from a base class named WebPart in the System.Web.UI.WebControls.WebParts namespace.

When creating WSS 3.0 Web Part pages, you should use the WebPartZone control defined in the Microsoft.SharePoint.WebPartPages namespace. You do not want to use the WebPartZone control contained within ASP.NET 2.0.

Different controls contained in a WSS-style Web Part page

The preferred way to create Web Parts for WSS 3.0 sites is to create the ASP.NET style WebParts. As discussed before, this means inheriting from the WebPart base class in the System.Web.UI.WebControls.WebParts namespace and overriding the RenderContents method.

Sharepoint Standard Versus Enterprise Edition

MOSS 2007 comes in both Standard and Enterprise Editions. Based on the needs we can choose to implement Standard Edition and upgrade to Enterprise Edition at a later time, or
immediately implement Enterprise Edition with all of its additional features.
Although there are many small differences between the two editions, the following are
the significant features included in Enterprise Edition but not in Standard Edition:

Excel Services
This feature provides access to Excel spreadsheets through a web browser and
offloads the calculations to the server. It makes only specific areas of the spreadsheet
visible to users, and ensures that there is “one version of the truth,” since
only specified users can modify the underlying data.

Report Center
This is a site provided out of the box that has been designed to simplify the management
of reports and data connections.

Business Data Catalog
This feature is a simplified way to bring data from external sources into Share-
Point without costly custom development. With it, users do not need to access
multiple systems to view the data they need—it is all available from one common
interface provided by MOSS.

Business Data Search
This feature allows users to search data that has been stored in separate systems
exposed through MOSS (such as those connected via the Business Data Catalog).

Forms Services
You can create forms within Microsoft Office InfoPath 2007 and publish them to
SharePoint using Forms Services, allowing users without the InfoPath client to
complete forms entirely through their web browsers.
