Data structures are a foundational concept within computer science and software development. These provide the tools you need to organize and store your data鈥攕kills every programmer needs to write scalable and effective code. In fact, data structures (often paired with data algorithms) are frequently one of the first concepts introduced to beginner programmers.听

You likely won鈥檛 find any certification options devoted solely to data structures. However, you can choose from several data science credentials that include the topic within their robust frameworks. Additionally, you can also consider completing an online course, especially one that provides a completion certificate, to help demonstrate your knowledge and skills to potential employers. To find the right learning option for you, explore some popular options that can help you build confidence and competence in data structures.听

What does a data structure certification and course cover?

A typical data structure course or certification will focus on how you can store, organize, and manipulate your data efficiently. Data structures are containers that allow you to organize and format your data in a way that your computer program or system can process and retrieve it. This provides a way for your program to perform tasks like searching, updating, or deleting data.

Something to note is that data structures go hand in hand with data algorithms. While data structures define how you store data, algorithms define how you manipulate this data. Many courses teach both together, so you can learn to write efficient code and solve complex data challenges.

Data structure basics

Data structure courses typically introduce you to basic structures and when to use each. When learning about data structures, you鈥檙e likely to come across common data structures such as the following.

础谤谤补测蝉听

With an array, you can store elements in a fixed-size, ordered list. You might also use arrays for sorting and searching, which is considered a foundational element for other data structures. For example, if you were recording learner test scores, an array might look like:

Test_scores = [97, 85, 72, 99, 89]

Linked lists

A linked list is an arrangement of data elements in which every element points to the next. You might use this if you鈥檙e organizing a playlist, instructions, or a series of events. You can insert and delete items easily with this structure, without having to redo the series. If you were creating a lineup for a music festival, your linked list might look like:

Set 1 - Set 2 - Set 3 - Set 4

A stack is a structure that follows the 鈥渓ast-in, first-out鈥� rule. You can think about this like stacking bricks. The top brick is the most recent element you added, and only the brick on top of the stack can be removed. If you want to remove or use recent items, this structure provides convenience.听

The 鈥渦ndo鈥� button on your computer is a prime example of this. When you press 鈥渦ndo,鈥� it eliminates the most recent action you took.

蚕耻别耻别蝉听

Queues are the opposite of stacks鈥攖hey follow the 鈥渇irst in, first out鈥� rule, which means the first element you add will also be the one removed first. You might use this type of structure to create priority queues, especially when it comes to waiting lists.听

This type of structure is helpful for call centers, for example, where the representative should connect to the caller who has been on the line the longest.听

Trees and graphs

If you have interconnected data with a hierarchical structure, trees and graphs provide a way to organize data. With a tree, you could search people in a company based on who they report to or the department they are in. With a graph structure, on the other hand, you have more flexibility to define complex connections between entities, such as mapping social networks or clusters of people within organizations.

Hash tables

If you have a large amount of data that you want to be easily retrievable, a hash table uses a hash function to store unique data values. This is essentially a digital key that corresponds to a particular location in the computer鈥檚 memory. By using the hash, you can quickly search, add, and remove data from the structure.

A typical example of this is a phone book. By entering a specific number or name, you can quickly find the information of the person or organization in the directory.

3 data structures certification options

Certifications offer industry-recognized credentials that affirm you have particular skills or knowledge. Although no providers offer certifications specific only to data structures, you might consider a data science accreditation that includes data structures as part of its scope. After all, having a solid understanding of data structures and algorithms is essential for storing and exchanging data, creating big data applications, and managing resources. A few examples to consider include the following.听
