What is a Data Connection Library in SharePoint Server 2010?
A Data Connection Library in Microsoft SharePoint Server 2010 is a library that can contain two kinds of data connections: an Office Data Connection (ODC) file or a Universal Data Connection (UDC) file. Microsoft InfoPath 2010 uses data connections that comply with the Universal Data Connection (UDC) file schema and typically have either a *.udcx or *.xml file name extension. Data sources described by these data connections are stored on the server and can be used in standard form templates and browser-enabled form templates.

2. On the Site Actions menu, click More Options.
3. On the Create page, click Library under Filter By, and then click Data Connection Library.
4. On the right side of the Create page, type a name for the library, and then click the Create button.
