In conclusion, distributed database systems are complex systems that require careful consideration of several key principles, including fragmentation, replication, distribution, and autonomy. By understanding these principles and applying them to common exercises, we can design and implement efficient and fault-tolerant distributed database systems. The solutions provided in this essay demonstrate how to apply these principles to real-world problems, and provide a foundation for further study and exploration of distributed database systems.
