 > Wrapper for multiple databases with a JDBC-like connection
 
-Database-js implements a common, promise-based interface for SQL database access. Inspired by Java, it uses connection strings to identify the database driver. Wrappers around native database drivers provide a unified interface to handle databases. Thus, you don't need to modify your code (except the connection string) to change your database! 😉

Wrappers around native database drivers provide a unified interface to handle databases. Thus, you can change the target database by modifying the connection string. 😉
 
 Database-js has built-in prepared statements, even if the underlying driver does not support them. It is built on Promises, so it works well with ES7 async code.
