I’ve been provided two files, one is a .dat file, and the other is a .mdb file.
Yes, you read that right. The .mdb is a Microsoft Access Jet database. It’s small, <3MiB, so I presume only holds information for this single exam.
The .dat file is ~426MiB, and a hexdump of the contents look like meta data for channel names, etc. is there, along with channel data.
No clues to the internal structure though.
According to the file contents, these files came from a “WA Tecnologia” system, which seems to be a Brazilian company with a horribly broken website. wainfo.br
Would appreciate any info!
