7 Best Database Forensics Software Tools [Recover Deleted]

Many of our data records are stored in database management systems (DBMS) and in the event of a mishap or data breach or theft incident, there is both a legal and technical requirement need to adopt a database forensics investigation process using specialized tools to carefully uncover what had happened.

Most of the common DBMS are;

  • MySQL
  • Oracle
  • PostgresSQL
  • Microsoft SQL Server
  • MongoDB

Before we look at Database Forensics, we have to understand what is Digital forensics. it is a scientific application of analysing digital evidence, mainly used in a court of law and has several sub-disciplines such as cloud forensics, mobile phone forensics, etc.

Digital forensics is not to be confused with the concept of data recovery, although both are similar in many ways. Forensics, as a whole, is used for investigation purposes.

What is Database Forensics?

Database forensics is a sub-field of the digital forensics discipline that deals with the preservation, extraction, analysis and presentation of digital evidence and findings.

With scientific forensics in mind, it is often used in litigation, criminal investigation and organisational inquiry purposes. However, it can also be used as a specialized database extraction skill to query the database and find out what happened.

Examiners using database forensics tools can expect to be looking more in-depth, such as analysing file metadata, record timestamps, database artefacts and system artefacts.

Which are the Best Database Forensics Software?

Here are the seven (7) BEST Database Forensics software tools that you can use to analyse and recover deleted database entries.

  • Unrestricted Accessibility to the database files – no need for password or account info from the application system
  • Extraction and Recovery for the normal/deleted/damaged database files – e.g. tables, views, triggers
  • Multiple Analysis Functions – e.g. .keyword searching, SQL statement query, visual connection analysis
  • Patent File Craving Technology – extract, analyze and reorganize the fragmented database files

3. Forensic Toolkit for SQLite


This commercial forensic software suite is a must-have for any forensic investigators to make the tasks of recovering SQLite records from disk, image and database simpler.

The Forensic Toolkit for SQLite is a suite of three (3) comprehensive software tools namely;

  • The Forensic Browser for SQLite
  • Forensic Recovery for SQLite

The forensic software has a database searcher that automatically load all SQLite databases from folder and subfolders. Images are stored in the database are also automatically extracted and viewable by examiners in the built-in gallery interface.

SQLite Viewer has a hex viewer to examine BLOBs and export them to a file for further analysis.

7. dbResponder


dbResponder is a free, SQL Server forensics tool that is capable of automated preservation and advanced analysis of database artefacts.

The forensic tool is useful for data breaches preparation & response and is developed by Kevvie Fowler who is a partner and National Cyber Response leader for KPMG.
