An ODBC (Open Database Connectivity) driver is a software tool that allows programs to connect to different database management systems (DBMS) through a single ODBC interface.
One of the main tasks of ODBC drivers is to provide a standard interface to databases, which allows different programs, regardless of the DBMS used, to work with databases.
ODBC drivers connect to databases from different programs, such as Power BI. Power BI is a data analytics and visualization system developed by Microsoft. Power BI allows users to connect to various data sources, including databases, store and process this data, and create reports and visualizations.
To connect to a database in Power BI, an ODBC driver is used. Users can use ODBC drivers to connect to different DBMSs, such as Microsoft SQL Server, Oracle, MySQL, and SQLite, a lightweight solution for local data storage.
Power BI has several advantages, such as a user-friendly interface, many available visual elements, and the ability to integrate with various other Microsoft products. However, Power BI also has disadvantages, such as a learning curve for new users and limited functionality compared to more complex data analytics platforms.

What is SQLite?
SQLite is a popular open-source relational database management system (RDBMS) widely used in embedded systems, mobile devices, and desktop applications. It was created in the mid-1990s by Richard Hipp, and the SQLite Consortium now maintains it.
SQLite is unique among RDBMS because it is a file-based database management system that stores data in a file on disk rather than in a server-based system. This makes SQLite particularly useful in applications that require a lightweight database that can be accessed locally.
Key Features of SQLite Database
- Self-contained: SQLite is a self-contained database engine requiring no configuration or setup.
- Cross-platform: SQLite is a cross-platform database system, which means it can be used on many different operating systems, including Windows, Mac, and Linux.
Small footprint: SQLite is a small and lightweight database system, which makes it ideal for use in applications with limited resources.
- ACID-compliant: SQLite is an ACID-compliant database system, which means it is reliable and durable and ensures data consistency.
- Standard SQL support: SQLite supports standard SQL commands, making it easy to use and integrate with other database systems.
- Public domain: SQLite is in the public domain, which means it is free to use and distribute.、
SQLite is a reliable and easy-to-use database system well-suited for small to medium-sized applications requiring a lightweight and self-contained database.
