I am trying to extract information from a database belonging to an old Delphi program, it has DEF, REG and DAT files.<br />

Unknown Database, DEF, REG, and DAT file

Databases are organized collections of data, most commonly accessed through management systems including schemas, tables, queries and processes that allow users to enter and manipulate the information or utilize it in other fashions, such as with web applications or for reporting purposes.
