Duro

Duro is a completely open-source, relational database library that is written in C. The library is based on the principles put forth in "Databases, Types, and the Relational Model: The Third Manifesto" by C.J. Date and Hugh Darwen. Its primary aim is to adhere to the guidelines of the proposed database language D as much as is humanly possible using a C library. The ultimate goal of this project is to create the framework which can serve as a sound basis for a truly relational database management system (TRDBMS).

As an open-source database library, Duro provides developers with the necessary resources to get more acquainted with the intricacies of the Database language D. Given the fact that it is written in C, it means that it is compatible with many different kinds of software development frameworks, thereby providing a high degree of flexibility. The principles followed by Duro serve as a guide for developers who seek to make databases more accessible to programmers and users alike.

Overall, using Duro significantly simplifies the process of working with relational databases by making the database language more comprehensible and accessible. The precise and well-specified approach of the library guarantees a higher level of compliance with strict standards, which makes it an ideal tool for the more advanced user. The fact that all of these features are open source and free of charge make it an attractive alternative to other commercial options. The library serves as an invaluable learning resource for developers who aspire to hone their skills and to those who seek to familiarize themselves with Databases and the Relational Model.
