protocol, SQL dialect and database storage. It can quickly link applications and multi‐mode heterogeneous databases quickly. • Enhance: Capture database access entry to provide additional features transparently and distributed governance, applicable in a variety of situations such as Java isomorphism, heterogeneous language and Cloud‐Native. As the cornerstone of enterprises, the relational database has a huge database proxy, providing a database server that encapsulates database binary protocol to support heterogeneous languages. Currently, MySQL and PostgreSQL (compatible with PostgreSQL‐based databases, such

is positioned as a Database Plus, and aims at building a standard layer and ecosystem above heterogeneous databases. It focuses on how to reuse existing databases and their respective upper layer, rather database protocol, SQL dialect and database storage. It can quickly connect applications and heterogeneous databases quickly. • Enhance: Capture database access entry to provide additional features transparently and distributed governance, applicable in a variety of situations such as Java isomorphism, heterogeneous language and Cloud‐Native.

Apache ShardingSphere aiming at reasonably making full use of the database proxy, providing a database server that encapsulates database binary protocol to support heterogeneous languages. Friendlier to DBA, the MySQL version provided now can use any kind of terminal (such database proxy, providing a database server that encapsulates database binary protocol to support heterogeneous languages. • Totally transparent to applications, it can be used directly as MySQL/PostgreSQL
