DOLAP

The desktop OLAP market resulted from the need for users to run business queries using relatively small data sets extracted from production systems. Most desktop OLAP systems were developed as extensions of production system report writers, while others were developed in the early days of client/server computing to take advantage of the power of the emerging (at that time) PC desktop. Desktop OLAP systems are popular and typically require relatively little IT investment to implement. They also provide highly mobile OLAP operations for users who may work remotely or travel extensively. However, most are limited to a single user and lack the ability to manage large data sets.
