A trigger is something that causes something to happen. It also includes the meaning of operation and starting device. In
the IT
and web industries, a trigger is often software that performs a specific process when a specific event occurs. A typical example is Google Tag Manager (GTM)
tags
. Google Tag Manager often places tags on
pages (inquiry pages) and measures the number of conversions based on the number of times the tag is activated (fired). If the tag on the conversion page operates (fires) 10 times in a month, the number of conversions will be calculated as 10 times.
What is a database trigger?
A database trigger is a database management function. In addition, it is a type of stored procedure, and refers to a function that allows preset processing to be performed automatically when some operation is performed on a table. .
Database triggers are very useful in application processing. For example, if you want to perform processing across multiple applications, you can simplify the writing of individual applications by setting triggers. This reduces man-hours and improves work efficiency. On the other hand, it is important to note that using triggers has the disadvantages of degrading the performance of the individual application and slowing down the processing speed.
Triggers in programming
A trigger in programming is not much different from the meaning of a trigger alone. A trigger in programming is used to automatically perform B when A is performed. In this case, the process of A is called a trigger. For example, suppose you have a program that allows users to answer some questions on their device, and the screen transitions when the question is answered. In this case, a trigger has been placed on the user’s response.
Trigger is also used as a medical term.
Trigger is a word that you may be familiar with in the IT and web industries, but it is also used as a medical term. Trigger, as a medical term, refers to a tender point. Tender points are points that cause pain. For example, suppose a doctor presses a person who is suffering from stiff shoulders or lower back pain. The patient naturally feels pain, so in this case, the shoulder or lower back is the trigger in medical terms.
