 The database management - the file server
 The user interface – originated from DOS
 Scalability and load balancing - was not really
addressed
 Communications are synchronous.


The application - in financial terms the application
has financial instruments split between modules

Client Base – 14 companies
 Biggest installation – 35 workstations

After 12 years GAMA considered as the No. 1
at the Russian investment market and is
getting similar position on the rest of the post
soviet space.

Delphi
 The database - Interbase or MS SQL Server –
client server application
 The user interface – provided by Delphi 5
 Scalability was not properly addressed.
 Communications are synchronous.

Three development teams
 Hard to get APLers
 Hard to find right people

THE GROUTH CHALLENGE


Construction:
from 4 workstations per company in average
(15 competitors)
to big instalations up to 100 workstations [TATOIL]
(no competition)
Investments: “Think big”…
from 200 trades a day to 15,000 trades a day
from 5 WS to 40-50 WS per company

SOME PROBLEMS…









Having something to loose …
Too many products
Too many development teams
Too many software platforms
Too many duplications
Too old looking user interface
Too scale sensitive
Too complex to develop and support
Too hard to control
Not very efficient
Dyalog 2007

THE CHALLENGE WE FACE
 To
solve all listed above…
 Scalable
 Asynchronous
 Stateless
 KISS
Dyalog 2007

15
THE APPROACH

Re-use
Hybrid if that helps
Integrate as much as possible
Unify where possible

Only the best and proven tools

Dyalog APL (V11.1 as soon as possible)
Depart from Delphi (5->2006->C# in 2-3 years)

THE BUS
The ESB (Enterprise Service Bus) acts as he intelligent, distributed,
transactional, and messaging layer for connecting applications, diverse
data, and other services that are commonly distributed throughout an
Algorithm (Business Logic) Database
enterprise computing infrastructure.
Scheduler
The ESB
provides mediation, messaging, events, as well as the Business
Database
connection.
Service

A SOA (Service-Oriented Architecture) is a framework for integrating
business processes and supporting IT infrastructure as secure,
standardized components – services – that can be reused and
The Bus
combined to address business priorities.
