Migrating data from MS Access(.mdb; .accdb) to MariaDB

This guide walks you through migrating data from MS Access to MariaDB in a few simple steps using ESF Database Migration Toolkit. Simplify complex migration tasks and save valuable time with our streamlined approach.

MS Access vs. MariaDB:

Microsoft Access is a robust database management system (DBMS) that combines the relational Microsoft Jet Database Engine with a graphical user interface and software development tools. As part of the Microsoft Office suite, MS Access provides users with an easy-to-use platform for creating and managing databases, enabling efficient data entry, query execution, and report generation. It supports various data formats, allows integration with other Microsoft applications, and is ideal for small to medium-sized databases used in business and personal applications.
MariaDB is a powerful open-source relational database management system (RDBMS) that originated as a fork of MySQL. It was developed by the original creators of MySQL in response to concerns over its acquisition by Oracle Corporation. MariaDB retains compatibility with MySQL while offering additional features, improved performance, and enhanced security. It is widely used in various applications ranging from small-scale web databases to large-scale enterprise systems, thanks to its flexibility, scalability, and active community support.
