A version where MySQL has been replaced by PostgreSQL is called LAPP, or sometimes by keeping the original acronym, LAMP (Linux / Apache / Middleware (Perl, PHP, Python, Ruby) / PostgreSQL). [7] The LAMP bundle can be combined with many other free and open-source software packages, including: netsniff-ng for security testing and hardening
The nested set model is a solution to that problem. An alternative solution is the expression of the hierarchy as a parent-child relation. Joe Celko called this the adjacency list model. If the hierarchy can have arbitrary depth, the adjacency list model does not allow the expression of operations such as comparing the contents of hierarchies ...

The term "solution stack" has, historically, occasionally included hardware components as part of a final product, mixing both the hardware and software in layers of support. [ 4 ] [ 5 ] A full-stack developer is expected to be able to work in all the layers of the application ( front-end and back-end ).
By eliminating the MySQL server overhead, InnoDB has a small footprint and is well-suited for embedding in applications which require high-performance and concurrency. As with most embedded database systems, HailDB is designed to be accessed primarily with an ISAM -like C API rather than SQL (though an extremely rudimentary SQL variant is ...
I was super active growing up as a result of my parents’ example—my mom was into Jane Fonda workouts and my dad was constantly doing Fun Runs and Ironman races.Watching my father compete was ...
The join operation defined for relational databases is often referred to as a natural join (⋈). 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.
