When we talk about the "DDT2000 database of Renault vehicles," we are referring to a structured collection of .prc and .dta files (or .ddt files in modern variants). These files contain the exact communication parameters for each ECU type.
Renault uses a diagnostic protocol called DDT (often DDT2000 or DDT4ALL in aftermarket software). This is not a vehicle database but a communication protocol (like a language) for talking to Renault ECUs via the OBD2 port. The "database" would be a file (e.g., .ddt , .ddt4all ) containing parameter definitions (PIDs), actuator tests, and coding values for various Renault models. ddt2000 database of renault vehicles
