A database index is a data structure that improves the speed of read operations on a table or collection at the cost of additional storage and slower writes. Think of it like a book index — instead of scanning every page to find a topic, you look up the topic in the index and jump directly to the right page.
The N+1 problem is a common performance anti-pattern in database access where an application executes 1 query to fetch a list of parent records, then N additional queries to fetch related data for each parent — resulting in N+1 total queries instead of a constant number.
Fault injection is a testing technique that deliberately introduces faults or errors into a system to evaluate its behavior under abnormal conditions. The goal of fault injection is to improve the system's resilience, robustness, and fault tolerance by identifying and fixing potential weaknesses.
Remote Procedure Call (RPC) is a protocol that allows a program to execute code on a different address space (often on another machine) as if it were a local procedure call. Essentially, it enables communication between different parts of a system.
Big O Notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. It is used to describe the performance or complexity of an algorithm.
Comparison between Array, Linked List and List data structures.
Binary trees are tree data structures where each node has at most two children, which are referred to as the left child and the right child. The binary tree is a special case of the tree data structure where each node has at most two children. There are several types of binary trees, including...
Memory allocation is the process of reserving a block of memory for a program to use. The memory allocation process is managed by the operating system and is responsible for allocating memory to processes and programs.
In order to solve a problem in computer science with different algorithms, we need to compare the solutions in order to choose the optimal one. And today we are going to use these two metrics to compare the algorithms: time complexity and space complexity.123
