Framework for the Analysis of the Relational Structure

The data model is that the prospects in a database as an assembly is clearly entitled tables. Each table has a particular set entitled pillars, each pillar of the name (also called attribute), which vary within a particular table, but not necessarily between the tables. Application-specific pillar table must be atomic (ie, single elements of the facts and figures) and all of the same type. Ordered records held in relational databases are considered as lines in these tables. Each entry is therefore ordered brought up only a set of basic facts and figures pieces, each of the specified type. Form, as a result, moreover, is known as a flat document model.

Form, first proposed by Codd in 1969 and used exclusively in the context of database management systems, takes its name from the analogy that can be drawn between the table as described and the mathematical concept of ratio. In this analogy the table corresponds to a relative, strip (see table) in the set (with respect), and column names (of tables) in the organization (for). Using this analogy, Codd developed a variety of procedures in which dialects for the manipulation of the bench can be based and from which it is now widely used facts and figures sublanguage SQL happens.

Despite its name, which can be a source of disorder, the form does not provide for liaison between the lines in a variety of bench and only a restriction on the line within a specific table is that no two rows are identical. Each bar, in terms of shape, so unaligned individuals. It can only be associated with other lines of correspondence between the facts and figures were pieces that is a problem for users.

In this paper, different approaches of bilingual education will be defined and the history of bilingual education will be affected. Proposal 227 spores and several views of bilingual education will be discussed. The final output will show my feelings toward bilingual education.

There are many approaches that are used to instruct LEP students. Transitional Bilingual Education (TBE), which are currently included in the system of NJ schools to move LEP students in monolingual classes for two or three years. Such programs, as mandated by the students in their native language in the same academic level as their monolingual peers. After the appropriate level of English knowledge is attained LEP students have the opportunity to transfer skills to function successfully in monolingual classes. At the same time students are also enrolled in classes that teach them English as a Second Language (ESL) (CQ Researcher, 1996).

Bilingual advocates who prefer development of bilingual education (DBE) believe that the interim approach defeats the whole purpose of bilingual education because it doesn t support students in their native language. Critics prefer DBE, because it is designed to train students as their native language and English. Using this approach increase the student his or her skills in their native language ...
