What is Systemctl?

Systemctl is a command-line tool that allows for the management and monitoring of the systemd system and service manager. It consists of a range of system management utilities, libraries, and daemons that have replaced the previous System V (SysV) init daemon. With its various commands, systemctl proves to be a helpful tool in managing a server's services. It provides detailed information about individual systemd services as well as those that have system-wide usage.

What is MongoDB?

MongoDB is a documented database management system that does not require the description of a table scheme. It is representative of a NoSQL based system (NoSQL is an approach to implement a scalable database storage system within a flexible data model), which uses JSON like documents and database schemas often used in web development. It is written in C, C++, JavaScript, and since it is cross-platform, it allows one to deploy it on any platform.

It is an example of NoSQL systems (NoSQL - this is an approach to implement scalable db storage with a flexible data model), MongoDB uses JSON like documents and a database scheme. It is often used in web-development along with Big data. MongoDB is written in C++, C, and JavaScript. It is also cross-platform, which lets us deploy it on multiple platforms.

NoSQL refers to a database with a data model other than the tabular format used in relational databases such as MySQL, PostgreSQL, and Microsoft SQL. MongoDB features include: full index support, replication, high availability, and auto-sharding.
