请将以下段落 Scalars, in the context of programming, are considered simple variables capable of holding a single piece of data like a number or a character. Generally, they represent data that's straightforward and not compounded with other pieces of data. Lately, the usage of scalars has been notably increased across various programming languages to manage and manipulate data. With the growth of data-driven approaches in fields such as IoT (Internet of Things) and machine learning, the role of scalars in programming has only grown in importance. 让改写的表达更为正式，加强专业性。

在编程语境中，标量被视为简单的变量，能够存储单一的数据单元，例如数字或字符。通常而言，它们表示的数据性质单一，不与其他数据元素复合。近年来，标量的使用在各种编程语言中显著增加，以实现对数据的管理和操作。随着数据驱动方法在物联网（Internet of Things, IoT）和机器学习等领域的发展，标量在编程中的作用日益凸显，其重要性得到了进一步增强。
