Sql server analysis services - ssas, data mining & analytics 38 (662 ratings) instead of using a simple lifetime average, udemy calculates a course's star rating by considering a number of different factors such as the number of ratings, the age of ratings, and the likelihood of fraudulent ratings. Despite the popularity of various multidimensional techniques, there are serious problems in using them a major disadvantage is that they do not allow tests for statistical inferences for example, the analyst could not determine from paired comparison data whether the perceived differences between stimuli or pairs of stimuli are statistically . A ssas multidimensional data model is composed of different database objects like dimensions, measures, data source, aggregations, perspectives, etc in this chapter we will review all the major database objects that get developed in ssas database as a part of the data model. In section ii, two methods of data analysis is explained first is conventional query method or using simple sql and second method is multidimensional analysis and its different types in the next section we have shown the incapability of conventional query method by taking the real world example and by comparing the performance of both on the .
