The Single Nucleotide Polymorphisms (SNPs) are the variations encountered in DNA sequence generated due to single nucleotide alteration in genomic sequence. Recently, Genome-Wide Association Studies(GWAS) have revealed the significant associations between SNPs and d

New graduate students are typically unaware of the postgraduate admission criteria and procedures and may spend a substantial amount of time obtaining guidance from consulting firms to help them define their admission opportunities. But this methodology can be biased and misleading considering the

In [GT1] Goodman and Tay have proposed an approach based on the possible equivalence of M to a single (acyclic) join dependency (JD). We remark that their characterization does n

J. M. Taylor is based on focussing on the relevant parts of the database by reasoning forwards from the updates of a transaction, and using this knowledge about real or just possible implicit updates for simplifying the consistency constraints in question. Opposite to the algorithms by Kowalski/Sadri and Lloyd/

The main problem addressed in this paper is to determine whether a rule program can be computed as a relational algebra program, i.e., whether the initial semantics of the

This seems to be a major obstacle to achieve a clean integration of object-oriented databases and other paradigms of database programming in a modern type system of a programming language.
