Today, mainframes contain a considerable portion of business applications worldwide. It is estimated that the current inventory of production COBOL running on mainframes is 150 to 200 billion lines of code. Despite the efforts to change within the mainframe environment, these mainframes, nowadays, face major problems for host organizations due to a combined set of financial, business related, technical and organizational problems. Moreover, the factors like diminishing resources (COBOL programmers), lack of documentation, inability to integrate with other systems, increasing maintenance costs, etc. have caused the organizations search for migration solutions. To overcome this problem within the context of modernization, over the years several main migration approaches that ranges from simple screen scraping methods to complete re-write of applications or re-hosting of platforms have been developed. To contribute to the solution of this overall problem, this thesis proposes a methodology framework specifically for the COBOL/CICS based mainframes. The research studies in this topic within this field are mainly focused on the technical aspects whereas our concentration is covering not only that but the other essential aspects of the problem domain. These are organizational view, project management view and process view. Within the thesis study, a special interest is given to the modernization strategy selection among migration, rewrite, packaged and do-nothing alternatives. Experimental results are also provided within the thesis to prove the usability of the approach for this selection.

Automatic composition of semantic web services with the abductive event calculus Kırcı, Esra; Çiçekli, Fehime Nihan; Department of Computer Engineering (2008) In today's world, composite web services are widely used in service oriented computing, web mashups and B2B Applications etc. Most of these services are composed manually. However, the complexity of manually composing web services increase exponentially with the increase in the number of available web services, the need for dynamically created/updated/discovered services and the necessity for higher amount of data bindings and type mappings in longer compositions. Therefore, current highly manual web servic...
A service oriented collaborative supply chain planning process definition and execution platform Olduz, Mehmet; Doğaç, Asuman; Department of Computer Engineering (2008) Currently, there are many software applications handling planning, scheduling, material management, invoicing, workflow management within an organization. However, companies need to plan across a wider span of activities and need to collaborate with their partners to optimize the ''overall'' profitability. This requires collaborative planning within a supply chain and exchange of planning data. Collaborative Planning, Forecast and Replenishment (CPFR) is one of the most prominent initiatives on Collaborativ...
An approach for including business requirements to soa design Ocaktürk, Murat; Doğru, Ali Hikmet; Department of Computer Engineering (2010) In this thesis, a service oriented decomposition approach: Use case Driven Service Oriented Architecture (UDSOA), is introduced to close the gap between business requirements and SOA (Service Oriented Architecture) design by including business use cases and system use cases into decomposition process. The approach is constructed upon Service Oriented Software Engineering (SOSE) modeling technique and aims to fill the deficits of it at the decomposition phase. Further, it aims to involve both business vision...
Modeling of software as a service architectures and investigation on their design alternatives Öztürk, Karahan; Doğru, Ali Hikmet; Department of Computer Engineering (2010) In general, a common reference architecture can be derived for Software as a Service (SaaS) architecture. However, while designing particular applications one may derive various different application design alternatives from the same reference SaaS architecture specification. To meet the required functional and nonfunctional requirements of different enterprise applications it is important to model the possible design so that a feasible alternative can be defined. In this thesis, we propose a systematic app...
Efficient index structures for video databases Açar, Esra; Yazıcı, Adnan; Department of Computer Engineering (2008) Content-based retrieval of multimedia data has been still an active research area. The efficient retrieval of video data is proven a difficult task for content-based video retrieval systems. In this thesis study, a Content-Based Video Retrieval (CBVR) system that adapts two different index structures, namely Slim-Tree and BitMatrix, for efficiently retrieving videos based on low-level features such as color, texture, shape and motion is presented. The system represents low-level features of video data with ...
