-How to write SQL queries? How are SQL commands disassembled, optimized, and transformed into on-disk query commands step by step? How to implement a high-concurrency database? How to implement database failure recovery? What is NoSQL? This course will take you to deeply understand the internal details of relational databases, and after mastering the theoretical knowledge, you can use Java to implement a relational database that supports SQL concurrent query, B+ tree index and failure recovery.
+How to write SQL queries? How are SQL commands disassembled, optimized, and transformed into on-disk query commands step by step? How to implement a high-concurrency database? How to implement database failure recovery? What is NoSQL? This course elaborates on the internal details of relational databases. Besides the theoretical knowledge, you will use Java to implement a real relational database that supports SQL concurrent query, B+ tree index, and failure recovery.
 
-From a practical point of view, this course will also exercise your ability to write SQL queries and NoSQL queries in programming assignments, which is very helpful for building some full-stack projects.
