Medidata is offering also third option. Direct access using ODBC into replicated database which includes all Medidata Rave tables, so you can extract all needed data. We have build system based on these tables, we are extracting lot of tables once a day, full load for small tables every night and for big tables like datapoints we are loading incrementally during week and once in week we are doing full download. So we have all needed metadata in our datawarehouse, which we are using i.e. for creation of ClinicalViews like SAS datasets. So this happens automatized for every study every night. Data transfer is quite reliable even we are Finnish based company and we have to do transatlantic data transfer. I'm not sure if MediData is offering this for new customers, because when we started this project there was no Biostat gateway available.
