NCBI FieldGuide Types of Databases Primary Databases –Original submissions by experimentalists –Database staff review and may organize the data, but we don’t add/modify additional information –Records are “owned” and updated by their authors Examples: GenBank, SNP, GEO Derivative Databases –Human-curated (compilation and correction of data) Examples: Gene(LocusLink), Structure & Literature databases –Computationally-Derived Example: UniGene –Combination Examples: RefSeq, Genome Assembly, Domain databases
