: Advantage of using NULLS over Empty Strings or zeros: 1 NULL requires 1 byte 1 Empty String requires 1 byte (assuming VARCHAR) 1 Zero requires 4 bytes (assuming INT) You start to see the savings here: 8 NULLs require 1 byte 8 Empty Strings require 8 bytes 8 Zeros Require bytes On the other hand, I suggest using NULLs over empty strings or zeros, because they ' re more organized, portable, and Requir e less space. To improve performance and save space, focus on using the prope

Recently, we are considering developing a product inspection data management system for the factory to record the material quality inspection data during the production process.

easier to find and sort algorithms. For people who are new to data structures, there is usually such a question: why do we need to learn Data Structures? What is the relationship between them and algorithms? The title of a book published in 1976 by Niklaus Wirth, a Swiss computer scientist, is "program design = Algorithm + Data Structure". This classic famous s

Look over the article before found that the last record of continuous integration is 3 years ago, and only recorded two, is really ashamed. However, the continuous integration of the flame is always burning in the heart, hope this beginning can be some breakthrough. Testing is the cornerstone of continuous integration, and integration without testing is essentially meaningless. How to write a good test is the first question that lies before me. Let's
