Service Oriented Architecture (SOA) is an increasingly important software architecture, designed to flexibly connect separate components in response to rapid changes in the business environment. SOA focuses on the exchange of information between independent software components and on the reusability of the components by separating communication interface from internal implementation. There are several features of SOA that make legacy system modernization to SOA appealing in today’s world. These are loose coupling, abstraction of underlying logic, agility, flexibility, reusability, autonomy, statelessness, discoverability and reduced cost. Migration of legacy systems to SOA is an important problem. While migration of legacy data processing systems has been widely studied, migration of legacy web applications has not. In this thesis we review existing strategies for migration of monolithic legacy web applications to web services, noting the unique challenges due to the highly dynamic nature of the systems, poorly structured code, and weakly typed languages in web applications, and the need for automation to assist in the process. We present a new semi-automated framework for the analysis and migration of monolithic web applications to web services using source analysis and transformation techniques, and outline a set of source transformation steps that can be used to migrate existing legacy web applications to web services form. We demonstrate our framework on the analysis and automated restructuring of two large existing web applications to extract and migrate integrated internal features to independent, reusable web services. / Thesis (Ph.D, Computing) -- Queen's University, 2013-03-28 14:23:24.797

The purpose of this project is to help a growing company reform their static information system to a dynamic system compatible with growth. The solution consists of migrating the legacy system that they have in FileMaker to an open technology platform. To solve this specific problem “patterns” have been used and this project explains these general solution “patterns”. We understand patterns like a generic solution to persistent design problems. General solutions will not only be useful in this specific problem, but they will be useful in all kind of similar migration projects as well. This thesis gives a detailed explanation of how to apply these patterns into the AEMI specific problem and how they can be useful in the migration process. The solution of the problem then, is following the advice of “patterns” to achieve our goals; these goals are the requirements that are given from the company supervisor. After the migration process a redesign process must be done in order to organize the information. This redesign consists of organizing the migrated information as well as adding the new information in the correct place. This thesis focuses on the process of migrating from a legacy system to a MySQL system through the use of the generic solution called “patterns”.  The final result is a MySQL database with all the old and new information together in a more adaptable platform for the company’s scalability.

Detention and its role in international migration of foreigners in the Czech Republic Aims of thesis are evaluation of detention, its influence and role in migration processes of foreigners in Czech Republic, as a restrictive action against irregular migration which is applied within common homecoming politics of EU countries, followed by analysis of conditions and informal structures which are related to irregular migration issues in Czech Republic. Individual aims are accomplished in two steps. At first is discussed present knowledge of detention, its part in migration processes, and theoretical definition of irregular migration's and detention's issues. In theoretical section of diploma project is considered mainly the detention's function in migration process from the point of view of migration concepts, negative impact of irregular migration, smuggling and trafficking, client system, EU migration politics' approach to irregular migration, migration politics' restrictive instrument and measures leading to criminalization, securitization and extraterritoriality of irregular migration, law regulation of detention and its application within detention facilities in Czech republic. The second step comprises survey aiming on detention's function and influence in migration processes of 42 foreigners...

This is done considering ALEPH, Integrated Libray System (ILS) that migrated data to the Library Module present in the software called Sistema Integrado de Gest?o de Atividades Acad?micas (SIGAA) at the Zila Mamede Central Library at the Federal University of Rio Grande do Norte (UFRN) in Natal/Brazil. The methodological procedure used was of a qualitative exploratory research with the realization of case study at the referred library in order to better understand this phenomenon. Data collection was able once there was use of a semi-structured interview that was applied with (11) subjects that are employed at the library as well as in the Technology Superintendence at UFRN. In order to examine data Content analysis as well as thematic review process was performed. After data migration the results of the interview were then linked to both analysis units and their system register with category correspondence. The main risks detected were: data destruction; data loss; data bank communication failure; user response delay; data inconsistency and duplicity. These elements point out implication and generate disorders that affect external and internal system users and lead to stress, work duplicity and hassles. Thus, some measures were taken related to risk management such as adequate planning, central management support, and pilot test simulations. For the advantages it has reduced of: risk, occurrence of problems and possible unforeseen costs, and allows achieving organizational objectives, among other. It is inferred therefore that the risks present in data bank conversion in libraries exist and some are predictable, however, it is seen that librarians do not know or ignore and are not very worried in the identification risks in data bank conversion, their acknowledge would minimize or even extinguish them. Another important aspect to consider is the existence of few empirical research that deal specifically with this subject and thus presenting the new of new approaches in order to promote better understanding of the matter in the corporate environment of the information units / Este estudo se prop?e a analisar os riscos de tecnologia da informa??o (TI) decorrentes do processo de migra??o de dados do ALEPH para o m?dulo biblioteca do Sistema Integrado de Gest?o de Atividades Acad?micas (SIGAA) na Biblioteca Central Zila Mamede (BCZM), da Universidade Federal do Rio Grande do Norte (UFRN). Assim, os procedimentos metodol?gicos tra?ados constaram de uma pesquisa explorat?ria e qualitativa, com a realiza??o de um estudo de caso na BCZM para detalhar e compreender o fen?meno. O instrumento de coleta de dados utilizado foi a entrevista semiestruturada, aplicada a (11) onze sujeitos, lotados na Biblioteca e na Superintend?ncia de Inform?tica da UFRN. Para exame dos dados utilizou-se a an?lise de conte?do, mediante a t?cnica de an?lise tem?tica. Ap?s a transcri??o, os relatos foram relacionados ?s unidades de registro e ?s unidades de contexto correspondentes ?s categorias. Os principais riscos que emergiram na transfer?ncia dos sistemas foram: a destrui??o de dados; a perda de dados; a falha de comunica??o com banco de dados da Institui??o; paralisa??o parcial do sistema; a demora no tempo de resposta para o usu?rio; a inconsist?ncia de dados e a duplicidade de dados. Como implica??es constataram-se transtornos que afetam tanto os usu?rios externos quantos os usu?rios internos do sistema, ocasionando estresses, retrabalho e aborrecimentos. As medidas para a gest?o de riscos que surgiram com maior frequ?ncia foram: um bom planejamento, apoio da administra??o central e mais simula??es de testes pilotos. Para as vantagens dessa gest?o, tem-se a diminui??o de: riscos, ocorr?ncia de problemas e custos eventuais n?o previstos, al?m de possibilitar alcan?ar os objetivos organizacionais, entre outras. Infere-se, portanto, que os riscos na convers?o de base de dados em bibliotecas existem e alguns s?o previs?veis; no entanto, verificou-se que os bibliotec?rios desconhecem ou ignoram e n?o se preocupam em identific?-los, em uma convers?o de base de dados visando a minimiz?-los ou san?-los. Outro importante aspecto a considerar ? a exist?ncia de poucas pesquisas emp?ricas, voltadas especificamente para esse tema, havendo a necessidade de novas abordagens para elucid?-lo no ambiente corporativo das unidades de informa??o
