Highlight 1
JsonDB's core operations like GET, SET, DEL, and EXISTS are fully implemented and work reliably for basic key-value database functionalities.
Highlight 2
The support for multi-database management (up to 16 databases) is a standout feature, enabling developers to manage isolated data sets within a single system.
Highlight 3
The AOF persistence and automatic recovery on startup provide robust data safety and allow for a secure system restart in case of failure, ensuring minimal data loss.
Improvement 1
The user interface is entirely command-line-based, which could be a barrier for users who are more accustomed to graphical user interfaces (GUIs) or more intuitive systems.
Improvement 2
The documentation could be more comprehensive, especially for new users. Including more detailed examples of advanced queries or complex scenarios would enhance usability.
Improvement 3
While the CLI interaction mode is functional, providing a web-based interface for easier interaction would broaden the user base, especially for those unfamiliar with command-line operations.
Product Functionality
JsonDB could improve its product functionality by adding support for more advanced querying features, such as joins or filtering. It would also benefit from better integration with other data systems for easier import/export of data.
UI & UX
Since JsonDB is CLI-based, creating a more intuitive web or desktop GUI would significantly improve usability, making it more approachable for users who prefer graphical interfaces over command-line tools.
SEO or Marketing
Marketing strategies could benefit from targeting developers and teams interested in learning about database systems. Creating content that explains the educational benefits of JsonDB could help drive awareness. A strong social media presence and technical blog posts could also boost visibility.
MultiLanguage Support
JsonDB could expand its reach by offering multi-language support for documentation and possibly translating the system's CLI into different languages. This would help make it more accessible to global audiences, especially those in non-English speaking regions.

How can I start using JsonDB?
You can start using JsonDB by setting up the TCP server, which listens on 127.0.0.1:7989, and then interacting with the system through the CLI client by using various commands like GET, SET, and DEL.

What features does JsonDB support?
JsonDB supports basic key-value operations such as GET, SET, DEL, EXISTS, and TYPE. It also supports pattern matching, TTL management, and the ability to work with multiple databases (up to 16). Data is persisted via AOF, and the system also supports automatic data expiration.

How is data persisted in JsonDB?
Data in JsonDB is persisted using AOF (Append Only File) logging, which ensures that all commands are recorded for recovery on restart. The storage structure is file-based, organized in a three-level directory structure, and uses MD5 hash-based file naming for data organization.
