What is the difference between slicing and dicing?
To slice means to cut and to dice means to cut into very small uniform sections and the two actions are often performed sequentially. For example, a chef may first cut an onion into slices and then cut the slices up into dices.
How is slice operation different from dice operation?
The main difference between slice and dice in data warehouse is that the slice is an operation that selects one specific dimension from a given data cube and provides a new subcube while the dice is an operation that selects two or more dimensions from a given data cube and provides a new subcube.
What is the difference between slicing and dicing in Molap?
The Slice operation takes one specific dimension from a cube given and represents a new sub-cube which provides information from another point of view. The Dice operation in the contrary emphasizes two or more dimensions from a cube.
What is the difference between drilling down into a data cube and slicing a data cube?
Drill-down – increases dimensionality by splitting the data further. Slicing – decreases dimensionality by choosing a single value from a particular dimension. Dicing – picks a subset of values from each dimension. Pivoting – rotates the data cube.
What is the difference between a cube and a dice cut?
"Cube" means to cut food into pieces that are even, like a square. The size is usually about the same as the chopped pieces sizes; about 1/3 to 1/2". "Dice" means to cut food into even, small squares about 1/4" in diameter.
What is slicing and dicing in Python?
Selecting single values from a list is just one part of the story. It's also possible to slice your list, which means selecting multiple elements from your list. Use the following syntax: my_list[start:end] The start index will be included, while the end index is not.
What does slicing and dicing of data mean in Excel?
Slicing and Dicing a Set of Data The phrase “slice and dice” is used a lot when referring to the analysis of data. The Slicing part refers to filtering your data to focus on just a subset – essentially the “where” statement. Dicing the data refers to selecting which attributes we're grouping the data by.
What is slicing and dicing in STM?
Slicing and Dicing refers to a way of segmenting, viewing and comprehending data in a database. Large blocks of data is cut into smaller segments and the process is repeated until the correct level of detail is achieved for proper analysis.
What is slice and dice in SQL?
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 the difference between drill-down and slicing?
Unlike Drill-Down or Drill-Through which displays detailed information from the Top-Level information based on the contexts, slicers are used to filter the report contents based on certain values.
Which of the operations is used for slicing the data cube?
Slice: It selects a single dimension from the OLAP cube which results in a new sub-cube creation. In the cube given in the overview section, Slice is performed on the dimension Time = “Q1”. Pivot: It is also known as rotation operation as it rotates the current view to get a new view of the representation.
What is the difference between slicing and indexing?
What are Indexing and Slicing? Indexing: Indexing is used to obtain individual elements. Slicing: Slicing is used to obtain a sequence of elements. Indexing and Slicing can be be done in Python Sequences types like list, string, tuple, range objects.
What are the differences between slice and splice?
slice returns a piece of the array but it doesn't affect the original array. splice changes the original array by removing, replacing, or adding values and returns the affected values. When you use each one is up to you.
What is the difference between Slice and split?
Slice( ) and splice( ) methods are for arrays. The split( ) method is used for strings. It divides a string into substrings and returns them as an array. It takes 2 parameters, and both are optional.
What is a dice operation?
Operation DICE stands for Date Informed Community Engagement program and is driven by crime patterns. The goal is to reduce gun crimes by addressing prostitution and drug activity around crime attractor locations like liquor and convenience stores, restaurants, bars and hotels.
What is the difference between slicing and indexing?
What are Indexing and Slicing? Indexing: Indexing is used to obtain individual elements. Slicing: Slicing is used to obtain a sequence of elements. Indexing and Slicing can be be done in Python Sequences types like list, string, tuple, range objects.

Data Slice in BW IP | SAP Community
I have created a data slice with 2 customer exit variables. Whenever Query runs, these 2 will be filled and via a lock button in Workbook data will be locked. Problem is how can i call this data Slice
Slice and dice Definition & Meaning - Merriam-Webster
slice and dice: [idiom] to divide something into many small parts especially to use the result for one's own purposes.
What is slicing and dicing in business objects? - Data warehousing
What is slicing and dicing in business objects? Slicing and dicing of business objects is used for a detailed analysis of the data. It allows changing the position of data by interchanging rows and columns.
Why is it important to slice a cube?
It is important because it helps the user visualize and gather information specific to a dimension.
What is Figure 6?
For instance, Figure 6 shows a graphical representation of dicing for a particular produce, over a specific time span for a particular region. The subset shows the Cell phone market, in North America only for the year 2000.
Is dicing the same as slicing?
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 a zoom feature that selects a subset over all the dimensions but for specific values of the dimension.
What is rollup in a query?
ROLLUP is used in tasks involving subtotals. It creates subtotals at any level of aggregation needed, from the most detailed up to a grand total i.e. climbing up a concept hierarchy for the dimension such as time or geography. Example : A Query could involve a ROLLUP of year>month>day or country>state>city. When a roll-up is performed, one or more dimensions from the data cube are removed because the output would display blank for certain rows.
What is an olap cube?
An OLAP cube is a data structure that overcomes the limitations of relational databases by providing rapid analysis of data. It is a Multidimensional cube that is built using OLAP databases. OLAP cubes can display and sum large amounts of data while also providing users with searchable access to any data points so that the data can be rolled up, sliced, and diced as needed to handle the widest variety of questions that are relevant to a user’s area of interest.
What is slice in multidimensional array?
A slice in a multidimensional array is a column of data corresponding to a single value for one or more members of the dimension. It helps the user to visualize and gather the information specific to a dimension. When you think of slicing, think of it as a specialized filter for a particular value in a dimension. For instance, if a user wanted to know the total number of OPV products sold across all of the market locations (Europe, Far-Ease, North America, South America,) the user would perform a horizontal slice (shown in blue in Fig 1.)
How does a query work?
The Query calculates the standard aggregate values specified in the GROUP BY clause. Then, it creates progressively higher-level subtotals, moving from right to left through the list of grouping columns. Finally, it creates a grand total.
Why is a roll up removed?
When a roll-up is performed, one or more dimensions from the data cube are removed because the output would display blank for certain rows. With some guidance, you can craft a data platform that is right for your organization’s needs and gets the most return from your data capital.
What are the components of a data cube?
There are three components associated with any Data cube: Measures, Dimensions and Hierarchies.

What is the difference between a slice and a dice?
The main difference between slice and dice in data warehouse is that the slice is an operation that selects one specific dimension from a give data cube and provides a new subcube while the dice is an operation that selects two or more dimensions from a given data cube and provides a new subcube.
What is sliced in data cube?
Slicing selects a single value for one of its dimensions and builds a subset of the cube. According to the above diagram, the sales regions, products in the year 2005 and 2006 are sliced out of the data cube.
What is an olap cube?
An OLAP cube is a multi-dimensional array of data. Data as a cube with hierarchical dimensions help analyzing. The aligned data is easier to visualize and improves productivity.
What is data warehouse?
A data warehouse is a system used for reporting and data analysis, which support decision making. Firstly, the data from multiple sources is extracted, transformed and loaded into the warehouse. Then, analytics is performed using Online Analytical Processing Server (OLAP), which is based on the multidimensional data model.
