You can use Project with SharePoint Composites, too
The Guide to creating SharePoint Composites includes a 73-page download that explains SharePoint Composites. To quote from the download, “A SharePoint Composite combines data, documents, and business process in a useful, productive way. … A SharePoint Composite is a ‘do-it-yourself’ business solution.” The SharePoint Composites.docx handbook includes a detailed introduction along with common design patterns that can help provide ideas on how to integrate and present data for collaboration and BI, by using SharePoint.
Although the Office 2010 integration points section includes only a brief mention of Microsoft Project, the handbook overall is a useful introduction to the concepts. For those who work with Project and Project Server, the handbook can help to expand your view of what is possible – as well as what is useful. Similar terms you might have heard in the past include mashup and OBAs (Office Business Applications). The SharePoint Composites handbook extends those ideas specifically for SharePoint-based solutions.
