  2. Locatioin: St.Petersburg, Russia Established: 1990 APL: since 1979 First APL conference: 1990, Copenhagen People: 42+ Markets: Construction (planning and estimating software)Investment (asset management and trade settlement software) Dyalog 2007 GamaGlobal Infostroy

  3. GAMAGlobal Asset Management Assistant SeMaTrade Settlement Manager iFundFund Manager A0Construction Planning and Estimating Dyalog 2007 GamaGlobal The starting point

  4. 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 GAMA Dyalog 2007 GamaGlobal

  5. 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. GAMA Dyalog 2007 GamaGlobal

  6. 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. SeMa Dyalog 2007 GamaGlobal

  7. Client Base – 4 companies Biggest installation – 15 workstations SeMa position at the Russian marketis second to none. SeMa Dyalog 2007 GamaGlobal

  8. 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

  9. One of the best at the Russian market ifund Dyalog 2007 GamaGlobal

  10. 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 A0 Dyalog 2007 GamaGlobal

  11. Client Base >> 3000 companies Biggest installation – 92 workstations After 20 years A0 considered as one of the best at the Russian construction market Dyalog 2007 GamaGlobal A0

  12. 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 People Dyalog 2007 GamaGlobal

  13. 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 The grouth challenge Dyalog 2007 GamaGlobal

  14. 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 Some problems…

  15. To solve all listed above… Scalable Asynchronous Stateless KISS Dyalog 2007 GamaGlobal The challenge we face

  16. 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) Dyalog 2007 GamaGlobal The approach

  17. Dyalog 2007 GamaGlobal Keep it simple Parameters Input Data Computation Output Data

  18. Dyalog 2007 GamaGlobal Keep it simple Which computation Where to get the computationparameters Where to get the input data Where to store the results Parameters Input Data Computation Output Data

  24. Dyalog 2007 GamaGlobal The bus Algorithm (Business Logic) Database Scheduler Database Service Service Service The Bus

  25. Dyalog 2007 GamaGlobal 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 enterprise computing infrastructure. The ESB provides mediation, messaging, events, as well as the Business connection. Algorithm (Business Logic) Database Scheduler Database Service Service 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 combined to address business priorities. The Bus
