Identify predictive

models/patterns found in

historical data

Use those predictive models with

variables to score transactions & identify

the best possible future outcomes

Practical scoring approachesOff-line: Batch Scoring

On-line: External scoring function

On-line: Within a transaction, in-DB, real time - New with z/OS

Step 1 – Build the predictive model Step 2 – Execute the predictive model

Real time scoring of the transactional data in DB2 for z/OSSPSS & DB2 for z/OS

IBM SPSS Real-Time Scoring Adapter

for DB2 on z/OS

– Enables customers to score predictive

models built by IBM SPSS Modeler

directly within a specific online

transaction processing transaction that

is running with DB2 for z/OS.

Business Value

– Delivers better, more profitable

decisions, using the latest data, at the

point of customer impact

– Enables more informed customer

interaction • Improves customer service

• Increases revenue per customer ratio

• Heightens customer retention

– Improves fraud identification and

prevention• Reduces risk and exposure

Add Business Critical Queries on demand in zApps

Challenges

– IT refuses complex queries lasting too

long because of impact on production

workload.

– DB administrator needs time and tools

to tune the queries

– So queries where executed on DW

data and not in real-time on operational

data at the time of transactions.

Solutions

– IBM DB2 Analytics Accelerator• Complex queries are now acceptable!

• IDAA can be used as High Performance

Storage Saver. No data in DB2 for z/OS!

• IDAA Loader has several options for

data refresh.

• IDAA can be used for non-DB2 data

(IMS DB, VSAM, …)

– Workload management in z/OS• The optimized Mixed Workload

environment

• Performance goals assigned by

workload based on SLAs

Do things you could

never do before!

Integrate Hadoop & z Systems – 2 Use cases

1 - Mainframe clients want to

incorporate sensitive mainframe

data into exploratory analytic models

What has been holding them back?

z/OS

DB2 VSAM

QSAM IMS

SMF RMF

Logs

2 - Mainframe clients want to incorporate into

zApps analytics based on non-z data like

social media, machine generated data, e-mail

What has been holding them back?

There is risk associated with

having copies of sensitive data

existing outside the mainframe

Performance & Integration are key inhibitors

for real-time analytics.
