The DB3 format (or SQLite Database File) is a self-contained platform-independent database created by the open source SQLite Software library. In its simplest form, it's a single cross-platform application file, and can be used to store up to 140TB of data in an efficient format. It avoids additional server items, large databases and the associated licensing fees.
Technical Aspects
The most important feature of the DB3 is the ability to handle sql queries, so you can programme and create more complex queries than regular text files. A DB3 file is composed of 13 separate elements, such as tables, views, triggers and indices. Other crucial aspects include that it's completely ACID compliant, allowing developers to reliably modify concurrent transactions in multiple databases without compromising integrity by ensuring data accuracy and consistency. Further information such as the structure schema is also stored in the Database which helps to troubleshoot performance and execute ad-hoc reports. On a smaller scale, the miniature DB3 format makes it suitable for storing large datasets onmobile devices or embedded systems.
Comparison with Other File Types
The DB3 file extension offers a variety of advantages compared to other database files such as DAT, SDF, XLS, XLSX, MDB, and even graphical formats like GIF, JPG, and PNG. Not only does it provide a more straightforward and streamlined approach but the database file itself is highly compatible with many third-party software tools for development, analysis, visualization and general management purposes. Furthermore, DB3 files support encryption methods such as the popular ‘SQLite Encryption Extension’ that helps to protect sensitive data embedded within the table columns.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .DB3) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .DB3 extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .DB3 file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .DB3 extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .DB3 extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .DB3 file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .DB3 file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .DB3 file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .DB3 file) will be extended to the maximum.
It is also good to check
- if the .DB3 file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
