What are methodology for migration legacy system?5 answersMethodologies for migrating legacy systems include various approaches such as incremental migration, automated refactoring, and scaling through data migration. Incremental migration involves decomposing the legacy system into parts and defining the order of migration to control risks. Automated refactoring includes transforming the legacy system based on predefined patterns, creating abstract syntax trees, identifying coding violations, and generating new source code according to the target architecture. Scaling legacy applications for multi-tenancy can be achieved through migrating tenant data to new instances without application changes, leveraging external tables and foreign data wrappers. Additionally, migration strategies for automation control architectures in production systems towards Industry 4.0 involve evaluating business cases and migration paths to mitigate risks and optimize benefits.
How to use the remittance from the migrant workers?5 answersRemittances from migrant workers are primarily utilized for both consumptive and productive needs. The funds are commonly allocated towards daily consumption, children's education, religious ceremonies, home repairs, and production activities. However, studies indicate that in some cases, remittances are predominantly used for consumptive purposes due to being the main or sole income source for families of migrant workers. This trend is reflected in the prioritization of basic needs, home renovations, transportation, electronic equipment, and debt repayment over productive investments like land purchase, savings, business capital, livestock acquisition, and education. The utilization of remittances is crucial for economic stability and growth in both the donor and recipient countries, emphasizing the importance of effective financial management and investment strategies for migrant families.
What are the key traditional methods used by companies for data migration in ERP systems?5 answersTraditional methods used by companies for data migration in ERP systems include the identification of mappings between source and target data models at a conceptual level using informal textual descriptions. These mappings are then translated into programs by the implementation team to migrate the data. In some cases, rules on conceptual models are specified to ensure accurate migration. The overall approach aims to improve productivity and reduce migration errors. Additionally, companies may use tools and techniques for maintaining data integrity during the migration process. It is important to consider validation and integrity checks during the migration to ensure data accuracy. Companies may also evaluate various tools for migration, taking into account the complexity of the existing system and the specific business rules applied.
What are the benefits of using translation as a method?5 answersTranslation as a method has several benefits. It improves students' comprehension of the original text, increases reading speed, and enhances critical thinking and problem-solving abilities. It also aids in learning foreign languages and strengthens the expression of the mother tongue. In terms of practical applications, translation is used in various fields such as education, tourism, business, technology, science, and literature. Additionally, translation activities in language learning help students notice differences in structure and vocabulary, strengthen grammatical competence, and correct common mistakes. Translation practices also contribute to the development of vocabulary knowledge and overall language proficiency. Therefore, using translation as a method can be beneficial for language learners in terms of improving language skills, cultural understanding, and communication abilities.
Why people migrate?3 answersPeople migrate for various reasons, including the desire for better economic opportunities, improved living standards, and the pursuit of professional ambitions. Economic factors, such as poverty, lack of opportunity, and low living standards, can act as push factors, while prosperity, available employment, and higher living standards in the destination area serve as pull factors. Other factors that drive migration include social and political opportunities, as well as the need to escape unfavorable conditions, such as war, persecution, or discrimination. However, the decision to migrate is complex and involves weighing potential costs and benefits, including the cost of travel and accommodation, chances of finding work, and the impact on the household left behind. Modern communications play a significant role in migration decisions, as potential migrants learn about opportunities through the media, television, or from returnees.
How service migration is done?4 answersService migration is done through various methods and strategies. One approach is to use a multi-attribute Markov decision process algorithm for mobile edge computing, where service migration is performed to keep the distance between the user and the service within a small range. This algorithm considers factors such as service quality, resource demand, migration cost, and movement income of users to define the return function and reduce the number of migrations. Another method involves a detailed network service migration strategy, which includes planning migration steps, configuring ports, documenting the process, and verifying the performance of the new router after migration. Additionally, a service migration method can be implemented using a target mobile edge platform that receives a migration request, acquires a service endpoint, and sends a migration response to ensure the availability and reliability of the service for local mobile edge platforms. In a mobile communication network, migration of a stateless computation service can be initiated from a source compute node to a target compute node based on resource utilization and user demand.
