Download nucleotide sequences database

[alaa.arfaj]

Hello,

I want to build a BLAST tool to compare DNA seq with DNA database ex: GenBank.

And I want to store the DNA sequences database, comparison results, and other tables in SQL database.

Nucleotide sequences databases provided by NCBI is not created using tables, they are set of binary files so, I cannot store them in a relational database.

Is there is another place that provide the sequences database as a set of tables?

Hope you getting my point.

Best regards,
Alaa

I think Ensembl does, but I'm not sure.

Might be a bit big for a relational database ! We're talking terabytes of sequence information at the least for most useful databases.
