A person may have multiple contact information details. In Android, these multiple contact information details are joined and displayed as one contact detail. For instance; a person may have a Google+ contact, a Skype contact, and a phone contact, and Android joins all these contacts into one contact. Each of these sources of contacts is RawContact. Each RawContact has one or more data row, which holds some data about the contact such as phone number, e-mail, and so on. Refer to the following block diagram for a better understanding of their relationship:

Each RawContact has support for storing social network streams—texts and photos—with Android Ice Cream Sandwich. Each RawContact is associated with StreamItems which contains texts, timestamp, and comments from social media updates, such as Google+, and each StreamItem is associated with StreamItemPhotos which contains photos (such as photos in a Google+ post). However, there is a limit for the number of StreamItems stored in RawContact. This number can be fetched with a query with StreamItems.CONTENT_LIMIT_URI URI. When the number exceeds the limit, the stream item with the oldest time stamp is removed. The following block diagram depicts the relationship between these blocks:
