Thus slice operation produced a sliced OLAP cube by enabling the user to choose specific value for one of its dimension. Dicing on the other hand generates a subcube by picking two or more values from multiple dimensions of the cube. … Thus dicing and slicing allows detailed analysis of data from different angles.
What is slicing and dicing in OLAP?
Dicing is similar to slicing, but it works a little bit differently. When one thinks of slicing, filtering is done to focus on a particular attribute. Dicing, on the other hand, is more of a zoom feature that selects a subset over all the dimensions, but for specific values of the dimension.
What is OLAP slice?
A Slice represents two-dimensional view of an OLAP Cube that arranges data in a grid, similar to a spreadsheet; a Slice functions much like a report or a query in an RDBMS in that it returns data based on a request for what to see.
What is the major role of dice operation?
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.
What are OLAP tools?
OLAP (for online analytical processing) is software for performing multidimensional analysis at high speeds on large volumes of data from a data warehouse, data mart, or some other unified, centralized data store.
How is OLAP implemented?
Step one: dimensional modeling. Step two: select the data required for removing into OLAP system. Step three: data extraction for the OLAP system. Step four: loading data to the OLAP server.
What’s the difference between slicing and dicing?
To slice and dice is to break a body of information down into smaller parts or to examine it from different viewpoints so that you can understand it better. … To slice means to cut and to dice means to cut into very small uniform sections and the two actions are often performed sequentially.
