Model Database Components

Measure Represents factual data related

to a specific business process Examples: sales, cost, profit

Dimension Identifies and categorizes

measures Example: Location, Product,

and Time

Model Components

Hierarchy: A logical structure that groups dimension

members for the purpose of aggregating data

Example: Product Categories>Sub Categories>Products

Level A position in the hierarchy Example: Category, Subcategory

Members Distinct Values in a Level Example: PCs, Laptops, Monitors

Attributes Descriptive information about the

dimension members Examples: Color, Size, Weight

Necto Modeling Concept The Necto Model is a platform to connect data

from one or more data sources, and apply analysis upon it

Once a Model is Processed– authorized users can access it from within Necto WorkBoards

The Model is used for dynamic analysis, while achieving high security level

The Model Infrastructure is the SQL2012 Tabular platform, a sophisticated In-Memory engine

Necto Modeling Objectives Fast and scalable move to action: from a

business request to data modeling and live analytics

Giving administrators the ability to easily create sophisticated in-memory BI solutions

Giving Power Users and End Users the ability to easily create small – scale BI solutions

Building a simple Model is done with little help from the IT department, mainly around guidance and training

Fast browsing of aggregated and row-level data

Xvelocity – the Model Engine Necto uses the Tabular Xvelocity in memory

engine, that comes with SQL 2012. The engine has 3 main concepts:

In-memory column store… typical 10x compression

Brute force memory scans… high performance without tuning…

Basic paging … data volume mostly fits in physical memory

Necto Installation, Xvelocity Embedded Necto installation can include Xvelocity, with

the BI Ed. or Enterprise Ed. These editions supports the Xvelocity Engine It is a silent Installation.

Necto can also use an existing Tabular Instance for modeling
