WHONET SQLite data files


For the past twenty years, WHONET has relied on a simple but robust data file structure called dBASE (also known as DBF files), which has worked well for WHONET users for many years. WHONET and BacLink are now ready to support a newer and more modern data structure called SQLite which offers many advantages over dBASE.

Our new versions of WHONET support both the existing WHONET dBASE files, as well as the new WHONET SQLite files. You can use any combination of the old dBASE and new SQLite files without issue, assuming you do not have one of the compatibility problems referenced above.

Performance comparison

The below table gives examples of the performance improvement using WHONET SQLite data files using one year of data from a 700-bed hospital and over 70,000 samples.
