Data Migration to Cloud in ERP Implementations

The concept of Cloud Computing has evolved constantly, in strand of service models, based on the creation and share of several technological resources. Increasingly, it has used virtualization technology to optimize resources, which are shared by all accounts, in a self-service format. All these features result in a flexible and progressive behavior of resources. The management of the service provided, is made based on the service level agreement established between the client and the cloud provider, and the constant technological developments can quickly change depending of the requirements. That said, knowing the current state of Wipro with respect to the concepts of data migration and cloud being combined into one, it is very challenging to design and build a possible process to help the company make this transition. Especially, when there is already a tool that has been used for several years and it is intended to be part of this integration with a new possible solution that is described along this document. The study, of qualitative nature, is guided by different case studies when it comes to the processes being used to migrate data into Cloud. The main objectives are to find new solutions that increase productivity of the company, save human resources that can be reallocated to other tasks, ending up to be considered innovative solutions, with rapid implementations and most importantly with low cost. What ends up in the overall objective of this dissertation that is to examine the feasibility of the adoption of Cloud Computing in Wipro Portugal through two main points: • The migration of data into Cloud; • Integration with Data Conversion Tool (DCT). We believe that this approach is very meaningful towards encouraging greater productivity and obtaining new achievements. Concerning the empirical study, there is a big number of tools that can be investigated later as possible solutions for other kind of implementations than Oracle Retail. For now this dissertation focus in the current OR business approaches and points for Oracle Cloud as the main Cloud Computing Service due to its partnership with Wipro. Both solutions that were implemented, SQL Loader and Golden Gate, seem viable and versatile as they can be integrated with the current tool, DCT and are capable of loading several amounts of data without any issues. In terms of performance Golden Gate seems to be a few steps above of SQL Loader, but requires deeper analysis when using multi threading as an option in both methods, and the containerization of the databases can be very relevant regarding the times of loading. In general, good solutions are available and need to be taken into consideration by the company as they can help to leverage its resources in a more efficient way and the main objective of having data in the Cloud was reached, having gathered knowledge about the behaviour of Oracle Cloud and some of the services

Management implications of moving from a traditional structured systems development methodology to object-orientation

Thesis (M.S.) University of Alaska Fairbanks, 2003As software application systems become larger and more complex, many software employers and managers believe that the key to sustaining its competitive advantage in the computing technology market lies in its software engineering capabilities. Software crisis situation seems to be a common occurrence in the software development environment as systems become larger and more complex. Object Orientation (OO) has been proposed as a viable alternative to traditional approach (i.e., structured techniques), an approach that many hope will solve the current software crisis. 00 is a new paradigm, and it requires new types of knowledge, new specialists, and significant changes in the mindset, an entirely different way of thinking, representing and solving a problem. The transition of moving toward the 00 from the traditional approach may involve a high risk of failure if the managers do not understand the nature of paradigm shifts and do not anticipate the future. The problem of moving to 00 has become very important. An understanding of potential problems from migrating to the new paradigm helps managers make a smoother paradigm shift. The implications and challenges of the 00 paradigm are presented. The study suggests that Object-Oriented System Development (OOSD) requires more discipline, management and training than traditional software development does. Education and experience are keys for the success of any OOSD project

A Risky Business?

This book is about migration as a form of risk-taking. Based on Ukrainian women's experiences in the Polish domestic work sector, it presents a new approach to analyse movements of female migrants responding to the demand for household labour around the world. Risks involved in migration and in migrant domestic work are accounted for in detail alongside an analysis of the migration decision-making processes. This study shows how social ties and migrant institutions effectively reduce the otherwise radical asymmetry of power between an individual migrant, the state and an employer. A Risky Business? brings to light the complex risk structures of migrants' activities and their sophisticated responses to them. With their innovative strategies, migrants challenge government-imposed constraints and thus reduce the risks of migration

Wealth Constraints, Sharecropping Contracts and Transition to a Modern Sector

In a traditional agrarian sector tenancy contracts aloe farmworkers to produce and accumulate wealth. This is important in a dual economy characterized in its modern sector by a n high degree of credit imperfections. The wealth constrained workers can accumulate wealth by working as sharecroppers so that the next generation is able to invest in the modern, more efficient sector. W show that production in the traditional sector influenced the modern sector and vice versa,. Therefore the impact of north agrarian reforms and monetary wealth redistributions have to b evaluated regarding both the sectors and considering the possibility of intersectorial migration. We will see that for land poor economies agrarian reforms have an impact on the aggregate production while for land rich economies this can be totally ineffective. Furthermore there are equilibria where monetary wealth redistributions are preferred to the agrarian reforms.Sharecropping contracts, credit imperfections, wealth accumulation, agrarian reform, monetary wealth redistribution, dual economy, intersectorial migration

Sale of Visas: a Smuggler's Final Song?

Is there a way of eliminating human smuggling? We set up a model to simultaneously determine the provision of human smuggling services and the demand from would-be migrants. A visa-selling policy may be successful in eliminating smugglers by eroding their profits, but it also increases immigration. In contrast, repression decreases migration but fuels cartelized smugglers. To overcome this trade-off we show that legalization through selling visas in combination with repression can be used to weaken human smuggling while controlling migration flows. Our results highlight the complementarities between repression and selling visas, and call into question current policies

Global Risks 2015, 10th Edition.

The 2015 edition of the Global Risks report completes a decade of highlighting the most significant long-term risks worldwide, drawing on the perspectives of experts and global decision-makers. Over that time, analysis has moved from risk identification to thinking through risk interconnections and the potentially cascading effects that result. Taking this effort one step further, this year's report underscores potential causes as well as solutions to global risks. Not only do we set out a view on 28 global risks in the report's traditional categories (economic, environmental, societal, geopolitical and technological) but also we consider the drivers of those risks in the form of 13 trends. In addition, we have selected initiatives for addressing significant challenges, which we hope will inspire collaboration among business, government and civil society communitie

A Thesis Is a Product Is a Tracking

In this work, I discuss how global products/ identities are made, transported and consumed, and the inevitable ‘mis-’ in acts of transmission. This research ranges from the miscommunication in languages and linguistics, to the gap between production and consumption. I investigate how things and humans are misread, mispronounced, misfit and mistranslated when they traverse social and cultural borders, arriving at a place in between languages, holding on to and letting go of things that are familiar to neither and both cultures. This work explores diverse media such as publications, videos and installations, and examines how they maybe used to address such contexts as factory production, global trade, circulation and tracking of commodities as well as identities

Monitoring and mitigation of the sound effects of hydrocarbon exploration activities on marine mammal populations

Offshore Exploration and Production (E&P) activities, such as seismic surveys and drilling, generate sound that can affect marine mammals in different ways. These effects range from permanent or temporary auditory impacts to disturbance or behavioral changes, and communication masking. Depending on the intensity and duration of these effects, and without implementation of appropriate mitigation measures, this can result in population-level consequences. The overarching objective of this study was to advance the protection of marine mammals during the implementation of E&P activities through the following themes: (1) enhancement of the state of knowledge of risk management, (2) efficacy of mitigation, (3) advanced monitoring technology, (4) implementation of advanced industry monitoring and mitigation measures and (5) measurement of heretofore unassessed E&P activities. In this study several marine mammal monitoring and mitigation programs associated with E&P projects are presented to further advance these themes. Topics being addressed include the use of autonomous camera systems for aerial monitoring of a narwhal population, long-term photo-identification studies of western gray whales to better understand site fidelity to their summer feeding grounds, mitigation of gray whales’ behavioral responses to a seismic survey near these feeding grounds and use of Passive Acoustic Monitoring to characterize seismic pulses and drilling activity as well as marine mammal presence in remote arctic areas. A synthesis of the main findings is provided that includes identification of future research needs. Conclusions and specific recommendations are made that will contribute to our ability to assess and mitigate risks of E&P sound to marine mammals

On Locus of Control in Empirical Microeconomics

Investigating the psychological black box behind individual economic decision making is, without a doubt, one of the most prevalent concerns in recent empirical microeconomics. This is based on the urge of modern behavioral economics to provide the stochastic idiosyncratic shocks in standard economic models with meaningful content. Especially the growing availability of large microdata sources such as in longitudinal household panel studies has tremendously supported this scientific movement. This data regularly includes important self-reported information on inherent attributes such as personality traits which have a high potential of explaining large parts of the deviations which have previously been labeled as stochastic shocks and idiosyncratic errors. This is the point at which also this doctoral thesis lines up. The present thesis contains four studies that investigate the relationship of inherent personality traits with individual behavior and economic outcomes. Concretely, the studies address the domains female labor force participation, labor market mobility, drinking behavior and unemployment. The unifying element of all four studies is the focus on one specific personality trait within this context: the individual perception of control or locus of control (LOC). LOC is characterized as a ``generalized attitude, belief, or expectancy regarding the nature of the causal relationship between one's own behavior and its consequences'' (Rotter 1966, p.2) and describes whether individuals believe in the causal effects of their own efforts and abilities on their lives' outcomes. Chapter 2 initiates the discussion by analyzing the implications of LOC for female labor force participation. In the empirical analysis, internal women are found to have a significantly higher probability of being available for market production, which also translates into higher employment probabilities at the extensive margin. These effects are additionally found to be highly heterogenous with respect to underlying monetary incentives for participation and home production as well as prevalent social norms for working. In a quite similar manner, Chapter 3 discusses the role of LOC for regional labor market mobility within Germany. The empirical analysis identifies a distinct positive effect of an internal LOC on the general self-reported willingness to move as well as the probability of moving between regions. A prove that the importance of LOC for decision making cross the boarders of labor economics is provided within Chapter 4. The chapter is devoted to the question of whether LOC is also able to explain alcohol consumption as an important domain of risky health behavior. The study identifies a strongly positive effect of an internal LOC on moderate as well as regular drinking which is comparable to effect of traditional preference parameters such as risk aversion and time preferences. Eventually, Chapter 5 importantly contributes to the value all parts of this thesis adds to the body of literature on behavioral consequences of LOC by carefully discussion the stability of the trait and thus potential problems with reverse causality in the three other studies as well as in the existing literature in general. In order to access the stability of LOC, the study investigates the reaction of reported LOC to an exogenous unemployment shock. Reassuringly, the empirical analysis finds no long-lasting effects of job losses due to plant closures on LOC and thus cannot reject the common assumption of its stability during adulthood. Nevertheless, the study identifies an important temporary deviation in the measurement of LOC during periods of unemployment and therefore concludes that the reported LOC is affected by unemployment likely due to a situation-specific state effect
