· Slice: A slice is a subset of a multidimensional array (usually a two-dimensional representation) corresponding to a single value set for one (or more) of the dimensions not in the subset.

·   Dice: The dice operation is a slice on more than two dimensions of a data cube

·   Drill Down/Up: Drilling down or up is a specific OLAP technique whereby the user navigates among levels of data ranging from the most summarized (up) to the most detailed (down).

Slice is an operation where acts to divide up cube into a given slice (as how a slice of cake look like) to filter and extract the certain and neccessary information needed.
This kind of operation esential to help user visualize & gather information toward specific of dimension on how information being present in variety and useful ways

For instance: user want to know how the total number of iphone 6 being sold over the period of time (2014-2017). This way will show in a cube where the dimension of the business affected by product and time. User can easily spot the information and help in decision making on sales forecasting, custimer analysis.

The roll down operation (also called drill down) is the reverse of roll up. It navigates from less detailed data to more detailed data. It can be realized by either stepping down a concept hierarchy for a dimension or introducing additional dimensions

# data[].attributes.body
Roll up operation also called drill up. It performs aggregation on a data cube either by climbing up a concept hierarchy for a dimension or by climbing down a concept hierarchy, i.e. dimension reduction.
In addition, roll up refers to process of viewing data with decreasing detail.

drill down is to move deeper into a chain of data, from high-level information to more detailed, focused information, for example: drill down from year's data to monthly data to get the monthly information

Dice selects two or more dimensions from a given cube and provides a new sub-cube. For an organization, This tool is very useful in allowing them to get more detailed information on what goes in on a smaller scale.

Pivot is used to change the dimension of a data to be viewed from a different angle. For an example: in an organization,  sales of of product can be referred based on time(daily or monthly) or amount time can be referred  based on sales of product
