DQETool is the implementation of differential query execution in paper.

Requirements:

• Java 11 or above
• Maven (sudo apt install maven on Ubuntu)
• The DBMS that you want to test (currently support MariaDB, MySQL, TiDB, SQLite, CockroachDB)
• SQLite is an embedded database, which does not need extra setup and does not require connection parameters
• Other databases like MySQL, which requires connection parameters and needs to create a database named test
