The ODB file extension represents a database file created using the OpenDocument standard. It is primarily associated with LibreOffice Base and Apache OpenOffice Base, which are open-source database management applications. ODB files store structured data in tables, along with relationships between those tables, queries, forms, and reports. This format allows users to create and manage databases for various purposes, such as storing contact information, managing inventory, or tracking financial data. The OpenDocument format is an open standard, ensuring compatibility across different software applications and operating systems. ODB files are typically based on a ZIP-compressed archive containing XML files that define the database structure and data. This makes them relatively easy to inspect and modify, although it's generally recommended to use a dedicated database application for managing the data within the ODB file. The format supports various data types, including text, numbers, dates, and boolean values, allowing for flexible data storage and manipulation. ODB files are a good choice for users who need a free and open-source database solution that can be used across different platforms.
