It is a free application and you don't necessary to pay, only if you want to support this project.

Database Designer is a simulation and puzzle game where players take on the role of a database architect. The core gameplay revolves around designing and optimizing database schemas to meet specific requirements and performance goals. Players are presented with scenarios involving different types of data, user access needs, and performance constraints like query speed and storage efficiency. The challenge lies in selecting appropriate data types, defining relationships between tables, and implementing indexing strategies to create a robust and efficient database system.

The game mechanics typically involve a visual interface where players can drag and drop tables, define columns with specific data types (integer, string, boolean, etc.), and establish relationships like one-to-one, one-to-many, and many-to-many. Players must consider normalization principles to avoid data redundancy and ensure data integrity. They also need to understand the trade-offs between different indexing strategies, as indexes can significantly speed up query performance but also increase storage space and write overhead. The game often includes query execution simulations that allow players to test the performance of their database designs and identify bottlenecks. Successful database designs are evaluated based on factors like query execution time, storage space utilization, and data integrity. As players progress, they encounter more complex scenarios that require them to apply advanced database design techniques, such as partitioning, sharding, and denormalization, to handle large datasets and high query loads. The game aims to educate players about database design principles and best practices in an engaging and interactive way.
