We have had some discussions here in Sweden about better ways to distribute sequence databases. I need to have some statistics on the current development of the databases. 1) How big is the growth of the databases. Current and expected. 2) How many percents of the database is revised at each release. a) If you need to update a whole entry. b) If you only update the revised text in a relational db. I hope you can help me with an estimate for these figures.

Mats (hi there!), I think what would be of interest to you is the figures that are published in the Genbank newsletter. They state how many base pairs were there is release 55, 56, ..., how many new ones were added/revised. As far as the growth is concerned....folks expect to see greater increases over the next few years - now that NAR and other journals will be automating (or at least adding somewhat concurrently) whatever entries are published. -- shan -- Sharan Kalwani internet: shan%mcf.uucp@umix.cc.umich.edu uucp: ....!uunet!umix!mcf!shan

Now to my second quetsion. It may be more difficult to answer. Suppose you everyone has compatible RDBMS (Relational database management systems). Then you could use a scheeme where you update only those parts that are changed. Some months ago I got a paper from GB (Thanks again) that describes there thoughts on RDBMS and the future of GB. This was really interesting reading and fitted very well with our one thoughts. So, is it possible to estimate how many percent of a database that is really new and needs an update and how many percent that get updateted because you use ancient database technology. > > As far as the growth is concerned....folks expect to see greater > increases over the next few years - now that NAR and other journals > will be automating (or at least adding somewhat concurrently) whatever > entries are published. > > -- shan > -- > Sharan Kalwani > internet: shan%mcf.uucp@umix.cc.umich.edu uucp: ....!uunet!umix!mcf!shan -- --------------------------------------------------------------------------- Mats Sundvall +46/18174583 Biomedical Center mats@bmc1.BMC.UU.SE University of Uppsala, Sweden psi%24020010197020::MATS ---------------------------------------------------------------------------
