Legacy Systems Migration

Legacy System ModelAs the old adage goes, the more things change, the more they remain the same. Legacy systems, defined as those that have been inherited from languages, platforms, and techniques earlier than current technology, often do not instantly integrate with the latest cutting edge technology. Most enterprises have legacy applications and databases that serve critical business needs. The challenge in most instances is to keep the legacy application running while converting it to newer, more efficient systems.

At QSSI, our next-level approach helps shape your future without forgetting the IT roots. QSSI helps develop and integrate web services to solve point-to-point legacy integration problems. We help our clients leverage these services strategically across their entire enterprise implementing leading edge Service Oriented Architecture (SOA) processes and procedures including:

J2EE/.NET 3-tier Development

J2EE/.NET 3-tier DevelopmentDevelopment of business systems has gone through major changes as application development evolved into distributed systems resulting in increasing implementation complexities, frequent application changes, and rapid pace of deployment. The Presentation Tier, Business Tier and Database Access Tier comprise the 3 tiers in 3-tier Architecture and as 3-tier applications grew more complex, the 3 tiers have been further sub-divided into many more logically distinct tiers. The focus has been on the Business Tier as it can be divided into scalable and easily deployable sub-tiers. QSSI specializes in creating these scalable enterprise-wide business systems that integrate seamlessly to provide infrastructure manageability and availability.
