GAMA

Dyalog APL 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

Dyalog 2007 GamaGlobal

5

GAMA

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.

Dyalog 2007 GamaGlobal

SEMA

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.

7

SEMA

Client Base – 4 companies Biggest installation – 15 workstations

SeMa position at the Russian marketis second to none.

Dyalog 2007 GamaGlobal

IFUND

Delphi The database - MS SQL Server or any

conventional SQL DBMS. Client-server Could be better user interface. Delphi

5. Scalability - provided Communications are synchronous

Dyalog 2007 GamaGlobal

IFUND

One of the best at the Russian market

Dyalog 2007 GamaGlobal

10

A0

Delphi (used to be APL*PLUS II) The database - MS SQL Server – client

server application The user interface – provided by Delphi

5 Scalability was not properly addressed. Communications are synchronous

Dyalog 2007 GamaGlobal

11

A0

Client Base >> 3000 companies Biggest installation – 92 workstations

After 20 years A0 considered as one of the best at the Russian construction market

PEOPLE

42+ - the staff at the moment

Three development teams Hard to get APLers Hard to find right people Hard to keep them Sharp rise of salaries challenges the

developers time management and project management

Dyalog 2007 GamaGlobal

13

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 dayfrom 5 WS to 40-50 WS per company

Dyalog 2007 GamaGlobal

14

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 GamaGlobal

15

To solve all listed above… Scalable Asynchronous Stateless KISS

Dyalog 2007 GamaGlobal

THE CHALLENGE WE FACE

16

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 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 enterprise computing infrastructure.The ESB provides mediation, messaging, events, as well as the Business connection.

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 combined to address business priorities.
