The software has specialization to recover data files. To help extracting database and its objects from damaged file, there are two scanning options integrated with the tool:
Recovering data from a corrupt file depends upon number of factors. For example: Size of file, extent of corruption/inconsistency, what type of data is being stored in file etc. Understanding different concerns involved in database recovery, the software is designed with dual scanning options. Here is a discussion on which one to choose and why?
Quick Scan: The option helps in scenarios where size of database is not large. It will do one-phase scanning over the selected file and extract data (tables, stored procedures, views, schemas, triggers etc) from it.
Advance Scan: This option assures complete recovery from system database files. Software will scan file thoroughly if this mode is selected.
Recommendation: It is suggested to choose Advance Scan option as in any case it assures full data retrieval.
