INFO CUBE- Yasmin Banu A

INTRODUCTION

WHAT IS AN INFO CUBE? Info Cube is data storage area in which we

maintain data Info Cube is a set of relational tables that are

created according to the star schema An Info Cube can function as both a data

target and Info Provider Reports and analyses are based on Info Cubes A reporting user can define or execute queries

against an Info Cube Only Info Cubes physically contain data in the

database It is used to store summarized /

aggregated data for long periods of time

EXTENDED STAR SCHEMA: The benefits of star schema are slicing down,

easy understanding of data and performance increase

In extended star schema, “fact table” and “master data table”  is  connected  through SID (Surrogate ID)  table

In extended star schema , fact table and dimension table will be inside the cube

INFO CUBES: Info Cube consists of one fact table to store key figure

values and can contain a maximum of 233 key figures It usually has a minimum of 4 dimensions and a

maximum of 16 dimensions Of these, 13 are customer created and 3 are SAP

supplied dimensions: Unit dimension table: - Created only if there is at

least one key figure of type amount or quantity

Data Package dimension table Time dimension table

Dimension tables do not contain the characteristics/characteristics values, but the corresponding SID keys/values

Each customer created dimension can have 248 characteristics Info Objects

TYPES OF INFO CUBES: Infocube is classified in to three types based on the

way of maintaining and distributing the data1) Standard Info Cube:

Used to maintain the data physically in the cube

Read only is possible2) Virtual Info Cube:

It does not maintain data physically in the cube

During the query execution it brings the data

from respective source system3) Real Time Info Cube:

Stores the data physically in the cube Read and Write are possible It is significantly used in planning the data
