Betfair company

The world’s first and largest betting exchange

processes up to 20 million transactions each day and places more than 1,000 bets a second during peak periods.

The company has a 90% global market share with 1 million registered customers in more than 90 countries.

Problems of global databases

single instance of a database: It requires that users from disparate locations have

equal access. There must be some fields that have to be in a

common language. The servers that deliver the database would have

to be available 24 hours a day, 7 days a week. The network needs to be robust and fast.

Problems of global databases

Decentralised:

has problems when reporting is needed at the top. Requires very technical skills and a lot of time to do properly.

unsharable data.

Database system organization

At the beginning, in 2000 – just one database, in UK.

Due to company’s rapid expansion new exchanges in Australia and Malta, later in Italy were opened.

“Oracle’s scalability allows customers to jump from race to race at peak periods, with no loss in performance”

Database system organization

A logistics system tracks all services in every country.

A CRM application in turn provides complete reports for services.

“ Our Oracle Database ranks among the five busiest databases in the world, and we are the only bookmaker with sporting exchanges linked in real time,” says Rorie Devine, Betfair CTO.

Centralized & decentralized db

A centralized approach to data management promotes the development and use of integrated, sharable data , preserve the quality of that data and serve the needs of the business more effectively. A Global Information System (GIS) allows a company to have a single source for data. This enforces a unified process across the entire company and provides measurements and reports that are valid for every department.

In decentralized database management application developers, programmers, integrators perform the functions of a database analyst. Decentralizing data gives advantage in speed, but leads to poorly structured databases.

Technologies used

Oracle’s real-time technology, to meet the speed, performance, and scalability.

Oracle Products & Services used: Oracle Database Oracle Real Application Clusters Oracle Coherence

Linux operating platform: By switching to Red Hat Linux operating platform,

Betfair has generated a 75% improvement.

Oracle Real Application Clusters

With Oracle Real Application Clusters, the system extracts data from the front- and back-office applications, feeds it into the warehouse, and analyzes it to create management reports for decision makers.

Oracle Coherence

Coherence provides distributed data management and caching services on top of a reliable, peer-to-peer clustering protocol.

A cache platform that : facilitates transactions -> increases performance -> improves bet-matching speed.

Some facts…

99.998% of bets within one second, even during peak periods.

Transaction time - 23 milliseconds. Market share - a 90% of the betting

exchange industry. Queen’s Award for Enterprise and a National

Business Award for the Best Use of Technology.

Homogenous databases

all nodes use the same hardware and software for the db system.

The OS, data structures, db application must be the same or compatible.

Heterogeneous Databases

nodes may have different hardware and software .

Different computers and OS, db applications or data models may be used at each of the locations.

In our case…

Betfair company uses homogeneous db approach :

Red Hat Linux OP Oracle technologies

Data integration problem

Enterprises run different but coexisting IS. The integration of IS is becoming more and

more indispensable.

Aim: to form a unified new whole.

Data integration problem

DI means providing:– Uniform – Access to – Multiple – Autonomous – Homo/Heterogeneous– Structured– Data Sources

Solutions

Out-of-the-box encryption functionality Merge/purge technology Custom-designed software Sequential file processing for large volumes

of data.
