Before you learn about the why, how, and when to use a linked list data structure for your project it is crucial to conceptualize how a linked list works.
What is a Linked List?
A linked list is a linear data structure stored randomly in memory and is made up of nodes that contain a value and a pointer.
So, a linked list is a linear data structure. This means that the data is “chained” one after the other in a linear fashion. Think of it like you are waiting in line; people exist one after another. When you approach a line you know who is first and last in line by identifying that there are no people behind/in front of them, while every other person has one in front and one behind. Similarly, a linked list or any other linear data structure keeps its data in order one after another.

Data Quality Testing Skills Needed For Data Integration Projects. Data integration projects fail for many reasons. Risks can be mitigated when well-trained testers deliver support. Here are some recommended testing skills.
A data expert discusses the three different types of data lakes and how data lakes can be used with data sets not considered 'big data.'
The first step is to understand what is data governance. Data Governance is an overloaded term and means different things to different people. It has been helpful to define Data Governance based on the outcomes it is supposed to deliver. In my case, Data Governance is any task required for.
