A database connection is a facility in computer science that allows client software to talk to database server software, whether on the same machine or not. A connection is required to send commands and receive answers, usually in the form of a result set. Connections are a key concept in data-centric programming.
When connection pool configurations exceed these limits, issues such as rejected connections, throttling, or degraded performance can occur. Depending on how database limits are applied, overprovisioned connection pools can create significant resource contention as the server struggles to manage excessive simultaneous connections.
Various database systems, such as MySQL, PostgreSQL, and MongoDB, play distinct roles in organizing and structuring data. Effective database management ensures the responsiveness and efficiency of data-driven web applications. There are 3 types of databases: Relational databases: Structured databases that use tables to organize and relate data.

List scenarios for the new feature List the expected variants in the new behavior. “There’s the basic case & then what-if this service times out & what-if the key isn’t in the database yet &…”
If an object database is not used, the relational data model should usually be created before the design since the strategy chosen for object–relational mapping is an output of the OO design process. However, it is possible to develop the relational data model and the object-oriented design artifacts in parallel, and the growth of an artifact ...

YAML (/ ˈ j æ m əl /, rhymes with camel [4]) was first proposed by Clark Evans in 2001, [15] who designed it together with Ingy döt Net [16] and Oren Ben-Kiki. [16]Originally YAML was said to mean Yet Another Markup Language, [17] because it was released in an era that saw a proliferation of markup languages for presentation and connectivity (HTML, XML, SGML, etc.).
