software architecture is considered one of the most important indices of software engineering today. software architecture is a technical description of a system indicating its component structures and their relationships, and is the principles and rules governing designing. the success of the software depends on whether the system can satisfy the quality attributes. one of the most critical as...

Multi-tenant applications serve different customers with one application instance. This architectural style leverages sharing and economies of scale to provide cost efficient hosting. As multi-tenancy is a new concept, a common definition of the word and related concepts is not yet established and the architectural concerns are not fully understood. This paper provides an overview of important ...

Representational State Transfer (REST) has received a lot of attention recently as architectural style for distributed systems made up of loosely coupled resources. While most research in process enactment focuses on BPEL and SOAP, most internet applications are based on REST. To leverage this new architectural style also for process enactment, this paper introduces process enactment in REST en...

Architectural mismatches are a recognized obstacle to successful software reuse. An architectural mismatch occurs when two or more software components are connected to form a system and those components make differing and incompatible assumptions about their interactions or the environment in which they exist. Mismatch detection and avoidance has been previously discussed in existing literature...

There is a growing need to reduce the cycle of business information systems development and make it independent of underlying technologies. Model-driven synthesis of software offers solutions to these problems. This article describes a method for synthesizing business software implementations from technology independent business models. The synthesis of business software implementation performe...

This paper describes a timing tool being developed by a real-time research group at Seoul National University. Our focus is on the issues resulting from advanced architectural features such as pipelined execution and cache memories found in many modern RISC-style processors. For each architectural feature we state the issues and explain our approach.
