The term 'Field' appears in various fields, but the most common is in the field of computer science. In this article, Mytour helps you define the term 'Field' and understand it better in computer science.
1. What is Field?
Field is a term in English, and it means 'Field' in Vietnamese. Here, 'Field' does not refer to a field, but it refers to encompassing all contents within a certain scope. In reality, Field is used in various fields such as Mathematics, Physics, Photography, etc.
For photography enthusiasts, 'Field' is an essential term when discussing portrait photography because it's closely related to DOF (Depth of Field) – the area of sharpest focus in an image. Understanding and calculating DOF effectively is crucial for achieving beautifully blurred backgrounds and sharply focused subjects in photographs. Additionally, calculating DOF helps photographers determine which lens to use in different scenarios and how to capture the best shots.
In the field of mathematics (algebra), a field is a set where addition, subtraction, multiplication, and division are defined, and it has properties similar to operations on rational and real numbers.
Physics doesn't emphasize 'field' extensively, but it has its own definition. A field is one of the two forms of existence of matter, acting as the physical entity surrounding objects in space to facilitate interaction over distance and time. Simply put, a field is the space surrounding an object that experiences and transmits forces both in space and time.
2. Definition of Field in Computer Science – Computer Science
Returning to the main topic of the article, what does 'Field' mean in computer science and how are they used?
| Trong tin học, Trường (Field) chính là một phần nhỏ của các bản ghi / một phần của dữ liệu và có chứa rất nhiều dữ liệu. Field sẽ thể hiện thuộc tính của chủ thể cần quản lý trong các bảng. Thông thường, Field sẽ được gọi là trường dữ liệu. |
Example:
- Field Name – Column containing data attributes of names to be managed in the table.
- Field Old – Column containing data attributes of ages to be managed in the table.
To gain a better understanding of Fields, let's delve into 'Relational Database - Database'..
Relational databases have the task of organizing data into sets of database records - Records (simply understood as rows). Each database record will consist of several fields - Fields (simply understood as columns). This allows the system to quickly summarize all the data inside in both column and row formats.
In this article, Mytour has shared with you the definition of Fields and clarified their definitions in the field of computer science. Have a great day!
