A major advantage of using the Spring Boot Actuator is that it implements a number of production-ready features without requiring the developer to construct their own implementations. [18] If Maven is used as the build tool, then the spring-boot-starter-actuator dependency can be specified in the pom.xml configuration file. [19]

Maven 2 Central Repository [ 2 ] is used by default to search for libraries, but one can configure the repositories to be used (e.g., company-private repositories ...
In this type of join, two relations are connected by their common attributes. MySQL's approximation of a natural join is the Inner join operator. In SQL, an INNER JOIN prevents a cartesian product from occurring when there are two tables in a query. For each table added to a SQL Query, one additional INNER JOIN is added to prevent a cartesian ...
