what mean field "POS" it? what does this mean position? what the position is?

snp vcf

Can a file .vcf generate a SNP database?

what is a "SNP database" a RDMS ? define "generate"

yes, i will try to become a SNP database. generate == "be processed for". is there a journal / paper related with "snp database and vcf"? I'm sorry, I am still a beginner in learning in bioinformatics.

A variant must have a location in the genome. This location is denoted by the chromosome/contig (#CHROM column) and base position on it (POS column). Note that the position is 5', which is important mostly for indels, since this could otherwise be ambiguous. Have a read through the spec (this is a somewhat outdated version, but the principals are the same).
