Daewoo Securities faced numerous problems with its online trading systems. The problems were manifested in three crucial areas.

  • Due to a massive but typical influx of logon attempts between 9 and 10 am (at market open), the company’s DBMS system could not handle the load. As a result, logon attempts were unsuccessful and in-use disconnections were widespread. This basic dysfunction frustrated clients and ultimately led to a growing incertitude in Daewoo Securities’ ability to meet even simple needs.
  • Daewoo Securities had to assuage customers by indemnifying them, causing immediate negative impact on its profits. Worse yet, customer ill-will, loss of faith and viral spread of news related to the pervasive system limitations resulted in two vicious outcomes: large customer attrition and inability to attract new clients.
  • Daewoo Securities was embroiled in a crisis. Its profitability and reputation were suffering irreparable damage. Additionally, Daewoo Securities was facing the bitter reality of being left behind and passed by competitors. With the geometric growth of online trading in Korea, Daewoo securities was in need of a quick, implementable and seamless solution.[1]


Daewoo Securities adopted Altibase in in-memory mode for the first time in 2001. Since then, Daewoo Securities has adopted Altibase for its stock/future trading systems. Specifically, Altibase has eliminated authentication issues, which clears the path for speed, connection stability and complete logon reliability. Altibase has provided Daewoo Securities with stable performance that is 6 times faster and more reliable than its previous on-disk DBMS. Altibase, without and issues, processes more than 30,000 simultaneous logons.


  • Daewoo Securities no longer has customer-facing issues and related complaints, reputation risk and profit damage.
  • Altibase’s marked benefits are now integrated into the company’s main information system that processes and analyzes more than 2,000 quotes per second in multiple markets, including FX and options.
  • Altibase has increased Daewoo Securities’ data processing speed by 7 times.[2]
  • Daewoo Securities has achieved its number 1 position in market share since 2005.
  • Representing 8.5% total market share in 2005, Daewoo Securities is still maintaining its number 1 position with 10.0% market share in 2017.
  • Daewoo Securities’ continued growth is attributable to further adoption of Altibase in its main information processing system.
