B.R.I.D.G.E. TO DATA has been very helpful for initial screening data sources for a potential epi study. It provides broad, thorough, and detailed information on each database listed in the system.  It has been a wonderful tool to have, especially for feasibility evaluation.

B.R.I.D.G.E TO DATA (BTD) is the prevailing resource for capturing detailed global metadata on real-world databases.  The developers of BTD have spent meticulous thought into creating a process for collecting (and maintaining) data by building relationships with key data vendors across the world.  With the breadth and magnitude of global real-world data available, it’s a testament to the scientific staff at BTD to successfully achieve such an ambitious undertaking.

This "database" of databases is very useful in my day-to-day activities as it allows me to find quickly which databases will fit the best regarding the research questions I have. It is very complete and contains information on countries for which it is sometimes difficult to find information elsewhere.
