Understanding Data in SharePoint 2010
Whenever you design a data-driven application, regardless of the platform, you need to consider how your data is stored and managed. The data model addresses various aspects of data storage and management, including how and where your data is stored, how the relationships between different pieces of information are defined and managed, and how you will access your data.
When you work with SharePoint 2010, one of the first things you should consider is whether you can map your data storage requirements to the built-in data structures provided by the SharePoint platform. SharePoint defines a wide range of lists that can be used without modification or extended according to your needs by creating list templates, defining list instances, or associating content types you create to a list. The following are some examples:
- If you want to store a list of projects, together with descriptive information about each project, you can use a basic list.
- If you want to store statements of work (Word documents) and bid information (Excel workbooks) related to a project, you can use a document library with content types.
- If you want to store image resources for a particular project, you can use a picture library with content types.
This sounds intuitive, but one of the basic challenges of SharePoint development is to understand what SharePoint provides in order to avoid recreating existing functionality. Spend time exploring the list types and content types that are provided by SharePoint 2010, and consider how these components can meet your needs during the data modeling process.
This section provides an overview of the data-driven components in SharePoint 2010 and examines how they relate to the concepts of data modeling in general. The section includes the following topics:
