History of world migrations-kindle chapter 3 Essay

History of world migrations-kindle chapter 3 - Essay Example In the early modern duration, migrations again connected the continents by the process of colonization and also coerced migration of people or communities. Political issues such as citizen and alien were also introduced during the early modern migration period. Migrations changed pattern during recent history. The nation states together with the transnational federations identified new approaches of controlling individuals who migrated through their borders (Fisher 76). The migration process is illustrated chronologically and at different levels. For example, the migration involving individual communities, to the bigger migration patterns that entails collective movements of the big ethnic groups. The human movement processes involved; emigration, immigration and also migration. Emigration entails human movement away from a given locality like a state. Immigration involves movement into a place or territory like nation or town, Migration is the human movement from one place to another; for example, from one country to another. Migration process contributed directly to the diversity of the human population, because people adapted to different social, physical and natural environments. Human migration has been historically shaped by three factors; polities, environment and technology. Political factors like colonization lead to the migration of Africans to Europe and the Americas as providers of cheap or slave labor (Fisher 73). Technological developm ents in the telecommunication and transport sectors have enhanced movement of people; for example, from rural areas to urban areas in search of economic opportunities. Environmental issues like floods and droughts forced human populations to move to safer areas like the

Software Development Life Cycle - Assignment Example Software Development Life Cycle The protocol is able to support a variety of web pages and web applications ranging from basic to complex programming of computer games. To be supported in the web-server and data server hosting system, these web pages can be developed through various tools, as per its abilities, such as Dreamweaver and Front Page applications for developing simple web pages and similarly, Java, ICEFaces or .Net for developing complex applications. As per the referred use case, the information sharing process starts with the collection of raw sources from the internet which is then stored in the database servers prior to its transmission to the web servers. From the web servers, the information passes on to the routers and subsequently, the encrypted information is transferred to the end users through LAN, WAN and other internet servers. Before the information passes on to the web servers, as planned in the use case, it needs to pass through a web barrier, i.e. the firewall that restricts sharing of personal and unauthenticated information. System analysis and design principally refers to the systematic approach towards the designing and analysis of information transition systems or communication software. This particular approach is often regarded as Structured Systems Analysis and Design Method. In the referred use case, it can be observed that the designed SSADM intends to be operated by connecting external end users and internal end users on the basis of a complex web-server and database server system which will further be protected with a firewall application. Notably, a router has been considered to support the interface operations, in the SSADM. Theoretically, there are various stages which need to be followed when developing a SSADM. Fundamentally, six stages can be identified in the SSADM process, as listed below, Stage 1: Investigating the current problems associated with the systems operations to identify the need of SSADM Stage 2: Specifying the requisite features in the SSADM to evaluate and finalize option al methods in developing the system Stage 3: Selecting the most applicable technical options which can be appropriate to support the services required to be hosted by the information system Stage 4: Data designing to determine the range of data or information that can be served through the protocol Stage 5: Elaboration and feasibility check of the data transmission process planned on the basis of the developed SSADM through process design Stage 6: Designing the physical structure of the entire SSADM process (Shere2000, 2001) Database In the referred use case, appropriate procurement of relevant information is very much required in order to encrypt the information and its appropriate transition through the complex designing of the entire information system. Under such circumstances, new database server will be required to support the wide variety of schemas or tables. It is in this context that the different schemas will be required to support the vast range of information hosted by the web servers. However, the client will have another option of sharing databases over internet, using the systems of Microsoft SQL server and/or Oracle. Even though such mechanisms may be considered as useful in expanding the versatility of the server, it might also raise threats to data leakage being shared through cloud. Also, if the server application tends to use and XML methodology, it
