DevAssistant is a tool for Chrome for Developers. It is designed to help developers monitor, test, and manage websites using SQL databases. It is used to keep track of SQL queries and storage usage.

It can easily search tables or queries in the database, which can be used to see how many bytes have been read from or written to disk, how many times the connection has been opened and closed, and how long the page is currently loading.

It can also be used to query the database and see how much memory the program is using, how much memory is used in the individual databases, or how many of the tables or columns exist in the database.

It can easily monitor and analyze the page's HTTP requests and their associated data, as well as how much data has been read from or written to disk, how many times the connection has been opened and closed, and how long the page is currently loading.
