an open-source DBMS product is MySQL
The relational database management system MySQL is free and open-source. MySQL stores information in tables made up of rows and columns, just as other relational databases. Structured Query Language, or SQL as it is more frequently known, allows users to define, modify, control, and query data. The term MySQL is a combination of "My," the name of Michael Widenius, the man who created MySQL, and "SQL."
MySQL is the most widely used open-source database system in the world and is a flexible and strong program. It's used to store and retrieve data in many well-known apps, websites, and services as part of the widely used LAMP technology stack, which consists of a Linux-based operating system, the Apache web server, a MySQL database, and PHP for processing.

Explanation:
e. A fish starts at `-9` meters and changes `-11` meters?
The final elevation of fish starts at -9 meter than swims down another 11 meters which results in being -20 meters because it is below sea level.
How to find final elevation ?Final elevation refers to the height or altitude of a location at the end of a period of time or after a particular event. For example, if a fish starts at a certain elevation and swims to a different elevation, the final elevation of the fish would be the height at which it ends up after completing its swim. If a fish starts at -9 meters and swims down 11 meters, the final elevation of the fish would be -20 meters. The statement "swims down 11 meters" indicates that the fish is moving in a downward direction, and the magnitude of the change is 11 meters. This means that the fish's starting elevation of -9 meters is decreased by 11 meters to reach the final elevation of -20 meters.The fish starts at -9 meter
swims down another 11 meters
So Fish reached -9 - 11 = -20 meters

which action causes a before trigger to fire by default for accounts? updating addresses using the mass address update tool converting leads to contact accounts renaming or replacing picklist importing data using the data loader and the bulk api see all questions back next question
Note that the action that causes a trigger to fire by default for accounts is: "importing data using the Data Loader and the Bulk API." (Option D)
What is the rationale for the above answer?First, note that Data Loader is a client application for mass importing or exporting data. Use it to insert, update, delete, or export Salesforce records. When importing data, the data loader reads, extracts, and loads data from CSV (comma-separated value) files or database connections. When the data is exported, it outputs a CSV file.
A pre-trigger is an Apex trigger that fires before a record is saved to the database, allowing additional processing or validation of the record before it is saved. For accounts importing data using the Data Loader and Bulk API, the pre-trigger is enabled by default.
It is to be noted that updating addresses using the bulk address update tool, converting leads to contact accounts, renaming or replacing picklist values, and other actions generally do not trigger account pre-activators by default. However, if you want, you can write custom triggers that fire these actions.
