Schema
The BI concept in the DW is simple: one place to funnel data,
one direction of data flow, one model integrated prior to use.
Limited consideration for feedback loops and change

Success breeds failure
Organizational use of BI
matured over 25 years of data
warehouse history.
BI enabled a shift in managing
from the center of the
organization to the edge, and
that drives new requirements.
Needs have moved from basic
access to more advanced use,
and from the common data to
specific, local ad-hoc needs.

- Helmuth von Moltke the Elder,
talking about ETL specifications
Metadata is what you wished your
data looked like.
Reality is not requirements = code
Reality is the data, not the metadata
Exploring data defines metadata

the enemy.”

Changing analytics design assumptions
Past assumptions
▪ Center of the org
▪ Global use
▪ Common data
▪ Value in what’s
known, monitoring
▪ Data requirements
found in advance
Present assumptions
▪ Edge of the org
▪ Local use
▪ Specific data
▪ Value in what’s
unknown, discovery
▪ Data requirements
found during process

IT reality is multiple data stores and systems
Separate, purpose-built databases and processing systems for
different types of data and query / computing workloads, plus any
access method, is the new norm for information delivery.

An architectural history of BI tools
First there were files and reporting programs
We had cubes before we had RDBMSs!
Then we had hand-coded SQL, then QBE
Then semantic layers and SQL-generation
And now we’re back to files and cubes
But also new and improved:
Products that embed local and in-memory
datastores inside the tools so they can
deliver direct manipulation (wysiwyg) UIs

BI server architecture shifts
The SQL-generating server model of BI scales
extremely well but has poor user response time.
Solution 1: pre-cache
query results or prebuild
datasets on the BI server
(i.e. the old OLAP model)
Well-known problems
with this.
Solution 2: Shove all the
data into a BI server
repository. Avoids subset
problems. Adds potential
scaling problems.

There is always a third way
The previous choices were driven by client-server
thinking. We have a distributed (cloud) environment.
Possibilities:
Don’t force all the compute
into the DB or server.
Don’t force all the compute
to the client.
Data on demand, bring it to
the analysis from where it is,
or execute the analysis local
to where the data is.

On to Q&A
With that as framing:
▪ How is analysis functionally different from “classic” BI?
▪ What technology capabilities are important in an
analysis tool today?
▪ How does running in a cloud encironment influence the
internal architecture of the product?
