Our community's guiding development concept is Database Plus for creating a complete ecosystem that allows you to transform any database into a distributed database system. It focuses on repurposing existing databases, by placing a standardized upper layer above existing and fragmented databases, rather than creating a new database. The goal is to provide unified database services and minimize or eliminate the challenges caused by underlying databases' fragmentation. This results in applications only needing to communicate with a single standardized service. The concepts at the core of the project are `Connect`, `Enhance` and `Pluggable`. - `Connect:` Flexible adaptation of database protocol, SQL dialect and database storage. It can quickly connect applications and heterogeneous databases. - `Enhance:` Capture database access entry to provide additional features transparently, such as: redirect (sharding, readwrite-splitting and shadow), transform (data encrypt and mask), authentication (security, audit and authority), governance (circuit breaker and access limitation and analyze, QoS and observability). - `Pluggable:` Leveraging the micro kernel and 3 layers pluggable mode, features and database ecosystem can be embedded flexibly. Developers can customize their ShardingSphere just like building with LEGO blocks. ShardingSphere became an [Apache](https://apache.org/index.html#projects-list) Top-Level Project on April 16, 2020. So far, ShardingSphere has been used by over [10,000 projects on GitHub](https://github.com/search?l=Maven+POM&q=shardingsphere+language%3A%22Maven+POM%22&type=Code). ### DOCUMENTATION📜 <hr> [](https://shardingsphere.apache.org/document/current/en/overview/) [](https://shardingsphere.apache.org/document/current/cn/overview/) For full documentation & more details, visit: [Docs](https://shardingsphere.apache.org/document/current/en/overview/) ### CONTRIBUTION🚀🧑💻 <hr> For guides on how to get started and setup your environment, contributor & committer guides, visit: [Contribution Guidelines](https://shardingsphere.apache.org/community/en/involved/) ### Team <hr> We deeply appreciate [community contributors](https://shardingsphere.apache.org/community/en/team) for their dedication to Apache ShardingSphere. ## ### COMMUNITY & SUPPORT💝🖤 <hr> :link: [Mailing List](https://shardingsphere.apache.org/community/en/involved/subscribe/).
