Many databases are in the hands of international consortia.
Many databases were, however, not fully used.
In contrast to the secondary databases, many databases are created as primary databases by researchers.
Many databases are regularly updated, and the updated information is published in journals.
Many databases are useful in collecting numerous TSSs and have promoter prediction tools.
Many databases are already well established in this regard and indeed are leading policy development in these areas.
Many databases are not established for research purposes (primary data), but for quality control or for administrative purposes.
Many databases are accompanied by search functions such as BLAST or other computational features, which were supported by BioSlax for the databases that we tested.
Many databases were developed to provide researchers with different aspects of TCM information, but few of them are published, presented in English, and freely accessible.
Many databases are also rarely updated, difficult to navigate, provide information without rankings, maintain inconsistent coverage of information and/or lack a description of their methodology.
