4. Modelo Semántico
Analysis Services – SQL Server 2008 R2
Broad adoption
“Customers in the Magic Quadrant survey report that their Microsoft
average deployment sizes are now larger than any other vendor in
the survey in terms of users.”
“Use of OLAP functionality by Microsoft customers is more than
double that for the rest of the survey respondents.”
Source: Gartner Magic Quadrant for BI Platforms, 2011
Large ecosystem
"Wide availability of skills is among the top reasons customers select Microsoft over competing vendors.”
Source: Gartner Magic Quadrant for BI Platforms, 2011
Highest rated infrastructure and development tools
“Microsoft customers rate its BI platform infrastructure and development tools among the highest
compared to other vendors, and a higher percentage of customers use them extensively.”

5. Modelo Semántico
Analysis Services – SQL Server 2012
Build on the strengths
and success of Analysis
Services and expand its
reach to a much
broader user base
Embrace the relational
data model – well
understood by
developers and IT Pros
Bring together the
relational and
multidimensional
models under a single
unified BI platform –
best of both worlds!
Provide flexibility in the
platform to suit the
diverse needs of BI
applications

8. Modelo Semántico
¿Cómo debo construir mi modelo?
Depends on the application needs for each layer
Two Visual Studio (BIDS) project types in SQL Server 2012
Diplomado de SQL Server 2012

9. Modelo Semántico
Data Model
Familiar model, easier to build,
faster time
to solution
Advanced concepts (parentchild, many-to-many) not
available natively in the model…
need calculations to simulate
these
Easy to wrap a model over a raw
database
or warehouse for reporting &
analytics
Sophisticated model, higher
learning curve
Advanced concepts baked into
the model
and optimized (parent-child,
many-to-many, attribute
relationships, key vs. name, etc.)
Ideally suited for OLAP type
apps (e.g. planning, budgeting,
forecasting) that need the power
of the multidimensional model
Diplomado de SQL Server 2012

10. Modelo Semántico
Business Logic
Based on Excel formulas and
relational concepts – easy to get
started
Based on understanding of
multidimensional concepts –
higher initial learning curve
Complex solutions require
steeper learning curve –
row/filter context, Calculate, etc.
Complex solutions require
steeper learning curve –
CurrentMember, overwrite
semantics, etc.
Calculated columns enable new
scenarios, however no named
sets or calc members
Ideally suited for apps that need
the power
of multidimensional calculations
– scopes, assignments, calc
members

11. Modelo Semántico
Data Access and Storage
In-memory column store…
typical 10x compression
Disk based store… typical 3x
compression
Brute force memory scans… high
performance without tuning…
Disk scans with in-memory
subcube caching… aggregation,
tuning required
Basic paging … data volume
mostly fits in physical memory
Extensive I/O support… scales to
multiple TBs
Passes through DAX queries &
calculations… fully exploits
backend database capabilities
Passes through fact table
requests… not recommended for
large dimension tables
No support for MDX queries…
no support for data sources
other than SQL Server (in Denali)
Supports most relational data
sources…

ATRAVES DEL ESPECTRO DE BI
Personal BI
Team BI
Empowered
Corporate BI
Aligned
My Context
Our Context
The Org’s Context
BI solution created by
user. Context is only
for user & exists as
document.
BI Solution created by
power user. Context is
for a small team & it’s
managed on a server.
BI Solution created by IT,
Established corporate
context & is reusable,
scalable and backed up.
