The document discusses the concept of fast data, emphasizing its characteristics of volume, velocity, variety, and the importance of timely actions. It outlines strategies for effective fast data processing, such as smart gathering, filtering, and pattern recognition, as well as tools like Oracle Event Processor. Demonstrations showcase applications of fast data in various scenarios like tennis tournaments, car park management, and credit card theft detection.

3. Overview
•What is [special about] Fast Data?
–Continuous, Volume|Velocity|Variety, Real Time
•Challenges
–Volatile, non persistent
–Data => Information, Conclusion, Alert, Recommendation, Action
•Strategies
–Smart gathering
–Discard – filter, aggregate, pattern (and also look for missing events!)
–Promote (process, enrich)
–Visualize

Key strategy
•Discard – as early as possible (close to the source)
–Ignore irrelevant events
–Filter out unneeded attributes
–Takes samples instead of entire stream
–Aggregate: merge multiple events into one

Oracle Event Processor
•Light weight, real-time (sub-sub-second), in-memory, continuous query engine
–Available in embedded form – with corresponding licence
•Interacts with many different channels – inbound and outbound
•Has internal caches to enrich events and temporarily retain events
•Uses CQL to:
–Filter, aggregate, enrich and detect patterns (including missing events)

Channels help control the flow of data and can be tuned for optimal performance
Databases and Coherence caches can be referenced directly in CQL processors
CQL processors contain correlation, aggregation and pattern matching business logic
Output adapters send data and alerts to downstream systems and business processes

Demonstration: Live Tennis
•Tennis Tournament
•Many matches played in parallel
•The data that is produced:
–At a rate of up to 10 events/minute
Match Id, Player [who scored]
14,0

Demonstration: Live Tennis
•The information, conclusions & actions we are looking for:
–Scoreboard per game, set, match
–Match start and completion (action: inform next players for that court)
–Interrupted match (action: go and check out the reason for the interruption)

OEP application to process fast tennis data
•Preparation
–Define event definitions
–Create local, in memory cache with static, enriching data
–Gather (in this case generate) tennis data through adapter
–Create Event Sink to consume all findings and publish to console

Simple Time-slice Aggregation
•Produce aggegrates once every 30 seconds
–Count number of matches going on currently (meaning: in the last 30 seconds)
–Calculate average time per rally (over the last 30 seconds)
–Count total number of points played (over the last 30 seconds)

25. 25
Simple Time-slice Aggregation combined with all-time findings
•Produce aggegrates once every 30 seconds – partially over last 30 seconds and partially over ‘all time’
–Count number of matches going on currently (meaning: in the last 30 seconds)
–Calculate average time per rally and count total number of points played (all time)
–Longest rally played in the tournament

-The first player to have won more than 5 games
-and have won two or more games more than his opponent

30. 30
Detect interrupted matches by ‘finding’ missing events
•When a match is interrupted, obviously no more ‘rally point events’ are produced
•Detecting the absence of these events for a match [that has begun] is equivalent to detecting an interruption of the match
–Unless the match is complete because someone won

Credit Card Theft Detection
•Several situations in the past
–Credit card is stolen in the main terminal building
–Several purchases are made in shops on the way from that area to the main exit
•Purchases between $200-$500 dollar
•Purchases made within 5 minutes of each other
•Sometimes the purchases are made in not entirely the direct route to the exit

Credit Card Theft Detection
•Several situations in the past
–Credit card is stolen in the main terminal building
–Several purchases are made in shops on the way from that area to the main exit
•Purchases between $200-$500 dollar
•Purchases made within 5 minutes of each other
•Sometimes the purchases are made in not entirely the direct route to the exit
•To catch the perpetrator
–Consume the credit card purchase event stream for airport shops
–Spot situations where three or more purchases of $200-$500 are made within 5 minutes from each other and roughly in the terminal => exit physical order
–Publish an event to alert security staff
•To watch for any further purchases with that credit card
•To inform show staff for that credit card
•To send staff to the exit to try and apprehend the thief (perhaps based on the shopping bags he is carrying from the shops he bought stuff at)

Toilet Cleanliness
•Every toilet facility has a customer satisfaction station
–Every 30 seconds, someone can indicate (1-4) their satisfaction
•All entries are collected – signals (toiletId, rating)
•When the rating < 3.3 (average over last 5 signals) – the cleaning staff has to act
•When the rating < 3 and the
•previous signal for that toilet is longer ago than 5 minutes, then also action is required

40. 40
Human consumers
•Slow at data processing
•Not electronically connected
•Visually oriented (1 picture > 1000 words)
•Frequently (though perhaps decreasingly so) the actor or decision maker
•Interact along human communication channels
•Use visualization to present findings, conclusions, recommended actions
–And as a second tier of fast data processing: Highlight (filter), aggregate, patterns, extrapolate/interpolate, missing elements
•Sometimes take over from humans and just take action

Summary
•Fast Data (events): Vast, Continuous, Velocity, Variety
–Wanted: Near real time conclusions, recommendations, alerts, actions
•Strategy:
–Discard – as early as possible (Filter, Aggregate)
–Enrich, Pattern Match, Missing Events, Retain, Publish higher level, more coarse grained business event
–Repeat this cycle multiple times (such as rally point, game, set, match)
•Technology for Fast Data processing: Oracle Event Processor & CQL
–Interacts with JMS, EDN, RMI, HTTP (/REST), JMX, Database, Coherence
•To assist humans in Fast Data and Information Processing: Visualization
–Filter, Aggregate, Enrich, Pattern Match (1 picture > 1000 words)
–Technology: BAM (Dashboard and Rule processing), ADF Data Visualization
–Also: turn findings into actions using Human Task, BPEL and BPM via the SOA Suite 12c Event Delivery Network (EDN)
