Query: What is a data migration?
Post-migration: After data migration, results are subjected to data verification to determine whether data was accurately translated, is complete, and supports processes in the new system. During verification, there may be a need for a parallel run of both systems to identify areas of disparity and forestall erroneous data loss. Additional documentation and reporting of the migration project is conducted, and once the migration is validated complete, legacy systems may also be decommissioned. Migration close-out meetings will officially end the migration process.
The Mobile IP allows for location-independent routing of IP datagrams on the Internet. Each mobile node is identified by its home address disregarding its current location in the Internet. While away from its home network, a mobile node is associated with a "care-of" address which identifies its current location and its home address is associated with the local endpoint of a tunnel to its "home agent". Mobile IP specifies how a mobile node registers with its home agent and how the home agent routes datagrams to the mobile node through the "tunnel".
Mexico is one of the global centers of the child prostitution trade and a source and transit country for large numbers of migrants moving northward from Central America. There are an estimated 16,000 to 20,000 Mexican and Central American children who are trafficked for sex in Mexico. However, data on the number of victims of labor trafficking are not available. Additionally, the number of people trafficking into the United States from Mexico is known to vary widely, as do estimates of how many trafficking victims make such crossings.
As a part of the intense immigration process which Spain in general and Catalonia in particular have experienced over the last decade, there is a large number of immigrant languages spoken in various cultural communities in Catalonia, of which (Maghrebi) Arabic and Urdu are the most common if Spanish-speaking migrants are not taken into account.
The population in the mountain regions of Nepal has exceeded the carrying capacity of the land. Therefore, people are moving to the more arable lands of the Terai. It is estimated that 60% of Nepal’s population is concentrated in the hill and mountain regions, while 60% of farmland is in the Terai (Shrestha). The migrants hope to make a better life for themselves by moving to the agricultural hub of the country. However, these migrants are having difficulty finding affordable land.
Much of the migration to New Zealand took place from the constituent countries of the British Isles. This was facilitated from 1839 by the New Zealand Company founded for the purpose of colonization. The work of the Otago Association and Canterbury Association in establishing the primarily Scottish settlement in Dunedin and the primarily English settlement in Christchurch, respectively, encouraged further New Zealand-bound emigration from Britain.
MoveOn.org is a social movement organization to which resource mobilization theory can apply because it is a platform for people to either sign a petition or start a new petition. Coupled with political process theory, a social movement theory which posits that social movements either succeed or fail due to political opportunities, MoveOn.org has been a successful tool because of its accessibility, which would make people more likely to start a petition and move toward a common goal. In other words, resource mobilization applies to MoveOn.org because 1) the website itself is an existing resource that is accessible to consumers of the Internet which helps mobilize the goals of the organization and 2) that mobilization is essential to MoveOn.org's success. Also, resource mobilization applies because of the fact that the people who founded the organization knew how to utilize the resources available, which implies that anyone who uses the website to sign a petition or start a petition are rational social actors who act as utility maximizers, who weigh the costs and benefits before deciding to be a part of a social movement.
Long distance migration of the spruce budworm does occur as they can disperse across distances ranging from 20 to 450 km. In northern Minnesota, spruce budworm moths emigrate to the east lakeshore of Lake Superior in Ontario, Canada, because of seasonal changes. Dispersal is influenced heavily by temperature as low temperatures can slow down both take off and arrival. Other factors include dispersal direction, precipitation, altitude, and wind flow. It is likely that mass exoduses of the "C. fumiferana" over long distances are a result of food shortage in the local area.
Based on whole genome sequencing, humans may play a role in moving "B. pseudomallei" from place to place.
Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute (lower concentration of solvent). In biological systems, the solvent is typically water, but osmosis can occur in other liquids, supercritical liquids, and even gases.
Sex work and sex trafficking conflation is also a heavily debated legal topic. Several scholars argue that existing legal provisions aimed at combating human trafficking, such as the U.S. Trafficking Victims Protection Act and the 2000 United Nations Protocol to Prevent, Suppress and Punish Trafficking in Persons, especially Women and Children, do not adequately account for the variety of sex worker conditions and contexts, voluntary or involuntary. For instance, Filipina hostesses who migrate to Japan to work as entertainers must give up their legal documents to their recruiters during the migration process. While the law considers the process of giving up a passport to a third party intermediary as a condition of human trafficking, several scholars, activists, and the sex workers themselves do not regard this to be human trafficking, particularly when individuals consent to this component of the migration process.
The United Nations Population Fund lists Germany as host to the second-highest number of international migrants worldwide, behind the United States. More than 16,000,000 people are descended from immigrants (first and second generation, including mixed heritage and ethnic German repatriates and their descendants). 96.1% of those reside in western Germany and Berlin. About 7,000,000 of them are foreign residents, defined as those without German citizenship. The largest ethnic group of non-German origin are the Turkish. Since the 1960s, West and later reunified Germany has been attracting immigrants primarily from Southern and Eastern Europe as well as Turkey, many of whom (or their children) have acquired German citizenship over time. While most of these immigrants initially arrived as guest workers, Germany has also been a prime destination for refugees who have applied for asylum in Germany, in part because the German constitution has long had a clause guaranteeing political asylum as a human right; but restrictions over the years have since limited the scope of this guarantee.
Whether or not human trafficking and migrant sex work should be considered the same concept has been a contentious debate among feminist activists, government officials, scholars, and religious organizations for the past 15 years. This debate currently dominates much of the public discussion surrounding human trafficking and sex work. On one side of the debate are anti-prostitution activists who conflate migrant sex work and human trafficking because they do not believe in voluntary prostitution or because they view any migration for the purpose of sex work as human trafficking. This perspective has largely dominated mainstream governmental and NGO perspectives toward human trafficking across international contexts. On the other side of the debate are pro-sex work academics and activists who argue for the separation of voluntary migrant sex work from involuntary human trafficking and a greater focus on labor and migration rights instead of trafficking. This group works for the recognition of the right of prostitutes to pursue sex work as a legitimate form of work, more flexible and open borders for migrants, and a greater focus on the spectrum of coercive labor conditions.
Disk encryption generally refers to wholesale encryption that operates on an entire volume mostly transparently to the user, the system, and applications. This is generally distinguished from file-level encryption that operates by user invocation on a single file or group of files, and which requires the user to decide which specific files should be encrypted. Disk encryption usually includes all aspects of the disk, including directories, so that an adversary cannot determine content, name or size of any file. It is well suited to portable devices such as laptop computers and thumb drives which are particularly susceptible to being lost or stolen. If used properly, someone finding a lost device cannot penetrate actual data, or even know what files might be present.
Phoenix, a web framework written in Elixir, uses CRDTs to support real time multi-node information sharing in version 1.2.
It is considered that the Czech-Polish Croatian tribes were related to the Croatian tribes from Zakarpattia and Prykarpattia in Ukraine. They became separated during the migration period and seemingly formed one large Proto-Slavic tribe. It is theorized that the migration of those (White) Croatian tribes in the 7th century was the second and final Slavic migratory wave to the Balkans, which is related to the thesis by Bogo Grafenauer about the double migration of Slavs. According to this thesis, although it is possible that some Croatian tribes were present among Slavs in the first Slavic-Avar wave in the 6th century, it is argued that the Croatian migration in the second wave probably was not equally numerous to make a significant common-linguistical influence, while others considered they arrived in a significantly larger number. Zdenko Vinski and argued that the double migration thesis is supported by the rare findings of objects and ceramics of Prague-Korchak culture on the territory of Croatia, Bosnia and Herzegovina, and Serbia which were dated to the end of 6th and beginning of the 7th century (indicating first wave Slavs), and did not make a continuity with Slavic archaeological findings from the 8th-9th century, indicating assimilation. The Croatian tribes are also seen as a warrior group who assimilated into already present Slavs. In the territory of present-day Croatia they also gradually assimilated with the Pre-Slavic population because archaeology indicates a significant continuity of late antiquity population which have partially withdrawn to the mountains, coastal cities and islands.
Between 1905 and 1914, an average of one million immigrants per year arrived in the United States. Immigration officials reviewed about 5,000 immigrants per day during peak times at Ellis Island. Two-thirds of those individuals emigrated from eastern, southern and central Europe. The peak year for immigration at Ellis Island was 1907, with 1,004,756 immigrants processed. The all-time daily high occurred on April 17, 1907, when 11,747 immigrants arrived. After the Immigration Act of 1924 was passed, which greatly restricted immigration and allowed processing at overseas embassies, the only immigrants to pass through the station were those who had problems with their immigration paperwork, displaced persons, and war refugees. Today, over 100 million Americans—about one-third to 40% of the population of the United States—can trace their ancestry to immigrants who arrived in America at Ellis Island before dispersing to points all over the country.
Tandem's initial database support was only for hierarchical, non-relational databases via the ENSCRIBE file system. This was extended into a relational database called ENCOMPASS. In 1986 Tandem introduced the first fault-tolerant SQL database, NonStop SQL. Developed totally in-house, NonStop SQL includes a number of features based on Guardian to ensure data validity across nodes. NonStop SQL is famous for scaling linearly in performance with the number of nodes added to the system, whereas most databases had performance that plateaued quite quickly, often after just two CPUs. A later version released in 1989 added transactions that could be spread over nodes, a feature that remained unique for some time. NonStop SQL continued to evolve, first as SQL/MP and then SQL/MX, which transitioned from Tandem to Compaq to HP. The code remains in use in both HP's SQL/MX and the Apache Trafodion (Incubating) project.
Over 100 species reside in the Richmond Nature Park. Amongst the species that live in the nature park, there are at least 13 mammals including shrews, the douglas squirrel, mice, coyotes, and black tailed deer. Migratory birds have also been seen to be living in the park, including a variety of owl species, hawks, eagles, woodpeckers, and many more. Many of the bird species are considered to be "year-round residents", while other bird species are "found seasonally or during migration only". Over the past few decades since the park has been established, the numbers and diversity of the birds have changed with time as the bog-forest has developed and expanded, but there has been especially fewer waterfowl compared to what was there during the 1970s
On the other hand, ethnic Kazakhs and Uzbeks have been immigrating in large numbers to Kazakhstan ever since the collapse of the USSR. These immigrants come not only from the southern Central Asian states such as Uzbekistan and Tajikistan, but also from the Kazakh dominated areas in Xinjiang and Mongolia. The Kazakh government is actively encouraging the settlement of these compatriots (known as "Oralman") in Slavic dominated North and East Kazakhstan as well as the German dominated Karaganda Region, in order to dilute the minority populations there. There is also a low intensity immigration of ethnic Slavs from the less tolerant neighboring nations like Uzbekistan and Turkmenistan into Kazakhstan. An estimated 400,000 Uzbeks have migrated to Kazakhstan in recent years
According to a recent study, California great whites have migrated to an area between Baja California Peninsula and Hawaii known as the White Shark Café to spend at least 100 days before migrating back to Baja. On the journey out, they swim slowly and dive down to around . After they arrive, they change behavior and do short dives to about for up to ten minutes. Another white shark that was tagged off the South African coast swam to the southern coast of Australia and back within the year. A similar study tracked a different great white shark from South Africa swimming to Australia's northwestern coast and back, a journey of in under nine months.
These observations argue against traditional theories that white sharks are coastal territorial predators, and open up the possibility of interaction between shark populations that were previously thought to have been discrete. The reasons for their migration and what they do at their destination is still unknown. Possibilities include seasonal feeding or mating.
Data is stored on various media in files or databases, and is generated and consumed by software applications, which in turn support business processes. The need to transfer and convert data can be driven by multiple business requirements, and the approach taken to the migration depends on those requirements. Four major migration categories are proposed on this basis.
Basically, it repositions/moves the energy (seismic data) from the recorded locations to the locations with the correct common midpoint (CMP). While the seismic data is received at the proper locations originally (according to the laws of nature), these locations do not correspond with the assumed CMP for that location. Though stacking the data without the migration corrections yields a somewhat inaccurate picture of the subsurface, migration is preferred for better most imaging recorder to drill and maintain oilfields. This process is a central step in the creation of an image of the subsurface from active source seismic data collected at the surface, seabed, boreholes, etc., and therefore is used on industrial scales by oil and gas companies and their service providers on digital computers.
Migration: Hardware and software requirements are validated, and migration procedures are customized as necessary. Some sort of pre-validation testing may also occur to ensure requirements and customized settings function as expected. If all is deemed well, migration begins, including the primary acts of data extraction, where data is read from the old system, and data loading, where data is written to the new system. Additional verification steps ensure the developed migration plan was enacted in full.
The first two categories of migration are usually routine operational activities that the IT department takes care of without the involvement of the rest of the business. The last two categories directly affect the operational users of processes and applications, are necessarily complex, and delivering them without significant business downtime can be challenging. A highly adaptive approach, concurrent synchronization, a business-oriented audit capability, and clear visibility of the migration for stakeholders—through a project management office or data governance team—are likely to be key requirements in such migrations.
