2018年10月24日 · · 数据库的三范式（3nf）是设计关系型数据库时需要遵循的规范，主要目的是减少数据冗余、增强数据完整性和避免数据更新异常（如插入异常、删除异常和更新异常）。

2025年1月9日 · In database design, normalization is an important process to organize data, reduce duplication, and improve accuracy. The Third Normal Form (3NF) builds on the rules of the First (1NF) and Second (2NF) Normal Forms. Reaching 3NF ensures that the database is well-structured, efficient, and free from data issues or inconsistencies.

Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers. Examples: Express 3 in the form 3 = 3/1; recognize that 6/1 = 6; locate 4/4 and 1 at the same point of a number line diagram. 3nf3d Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

Alignment: 3.NF.A.3d: Compare two fractions with the same numerator or the same denominator by reasoning about their size. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

3.NF.A.3.C Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers. Examples: Express 3 in the form 3 = 3/1; recognize that 6/1 = 6; locate 4/4 and 1 at the same point of a number line diagram. 3.NF.A.3.D Compare two fractions with the same numerator or the same denominator by reasoning about their size.

2020年7月3日 · 3 Standard Text 3.NF.A.3 Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size. • 3.NF.A.3.A: Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line. • 3.NF.A.3.B: Recognize and generate simple equivalent fractions, e.g., 1 2 = 2 4, 4 6 = 2 3.

2020年12月21日 · 输入字段分割符，默认是以空格为分隔符，在日常中常常文本里面不都以空格分隔，此时就要指定分割符来格式化输入。 以上，test4里面字母间是以 “,” 来分割的，第一种写法，由于，没有指定FS,awk默认是以空格来分割，所以全部内容都当作$1来显示，第二个指定FS以 “,” 分割，所以能够正常打印。 输出字段分割符，默认为空格，如果读进来的数据是以空格分割，为了需求可能要求输出是以 “-“ 分割，可以使用OFS进行格式化输出. 输入行分隔符，判断输 …
