Introduction

The importance of English language for enhancing educational attainment through improved communication ability can never be over emphasized. Students who have so much difficulties with their communication skill in English language may not function effectively, not only in English language but in their academic and this is no reason than the fact that English language in Nigeria today is the language of text-books and the language of instruction in schools. When Students’ Proficiency in English Language is high, it will definitely affect and improve the academic performance of such students. Nevertheless, where the proficiency in English is lacking in any academic setting, it will definitely lower the academic performance of such students. [2] vehemently, revealed that lack of proficiency in English language is one of the factors contributing to poor performance in Mathematics. In his research, he observed that the performance of students in Mathematics’ examination at Senior Secondary School Certificate Examination (SSCE) is poor but further stated that the performance in English is more than that of Mathematics and this he linked to poor reading ability .He then suggests that there is need to improve the teaching of English language to improve Mathematics’ education.

[17] in his work proved that competency in English significantly determines performances in intelligence or academic tests. The revelation above seem to suggest that mastery of English language is very importance even in students’ academic performances in intelligence tests, especially when it comes to the issues of Science and Technical education that involves a lot of laboratory and workshop practical in the acquisition of skills. Technical Education is an aspect of education, which leads to the acquisition of practical, basic scientific knowledge which involves special manipulative…...

...dependency,so the relation is in 1st NF. 2 NF Decomposition: R1 (ABCD) with FD’s AB→C &C→D ,with AB is candidate key. R2 (BE) with FD B →E, B is candidate key. Here C→D is in 2nf but not in 3 NF ,so decompose R1 into 3NF . 3NF Decomposition R1 (ABC), with FD AB→C,AB is candidate key. R2(BE), with FD, B→E, B is candidate key. R12(CD),with FD,C→D,C is candidate key. This decomposition is in BCNF also. Example 2 R(ABCDEFGHIJ) with FD’s {AB→C,A→DE,B→F,F→GH,D→IJ} Here (AB)+=ABCDEFGHIJ, so AB is candidate key. Therefore A→DE, B→F are partial dependency which needs to be removed. So relation is in 1NF. 2 NF Decomposition R1(ABC),with FD AB→C,AB is candidate key. R2(ADEIJ),with FD’s A→DE,D→IJ,A is a candidate key. R3(BFGH),with FD’s B→F,F→GH, B is a candidate key. 3NF Decomposition In above decomposition D→IJ, F→GH is in 2NF which need to be decomposed. So, the decomposition is: R1(ABC), with FD AB→C,AB is candidate key. R21(ADE), with FD A→DE, A is candidate key. R22(DIJ),with FD D→IJ, D is candidate key. R31(BF),with FD B→F, B is candidate key. R32(FGH),with FD F→GH, F is candidate key. 8.Comparison with other manual approachs The Manual approaches defined in journals like “manual and automatic approach to normalize a database” and “normalization” by anuradha sharma is purely based on tables with no rules to determine keys and preserving decomposition criteria,so its quite difficult to understand the basics of......
