Expert Insights on Essential Programming Skills 

The expert insights provided below come from professionals across various industries who have collaborated closely with programmers.

1. Anna Harris, ESL Instructor, Californiadegree

“It is my belief that a significant number of programmers hold the belief that data structures and algorithms (DSAs) are merely academic requirements that do not hold practical application in the real world. However, they are taken aback by the prevalence of DSA queries in interviews. There are numerous rationales why organizations place value on the DSA knowledge of potential employees, and programmers ought to share this interest. Many organizations, including Amazon, Meta, Google, and Microsoft, consider code writing to be the last stage in a lengthy process. In reality, a programmer devotes the majority of their time to deliberating on the most effective approach to a given project, including the selection of optimal data structures and algorithms. Given that these choices significantly affect the organization’s utilization of resources and financial performance, it is unsurprising that DSAs play a prominent role in their interview procedure.”

A fundamental requirement of a programmer, in my opinion, is knowledge of fundamental database concepts. This is due to the fact that data is the lifeblood of businesses and permeates nearly every aspect of every endeavor. Although numerous programming languages are utilized to interact with databases, Structured Query Language (SQL, an acronym for sequel) is the most prevalent. Despite its 1980s inception, SQL continues to be the de facto standard language for interacting with relational databases and is regarded as indispensable by contemporary programmers. In recent times, PC databases have increasingly adopted SQL due to its ability to facilitate access to distributed databases, which are those that are geographically dispersed across multiple computer systems. This enables multiple local users to concurrently utilize the same network. Additionally, SQL facilitates the organization and storage of data in relational databases.”
