Build Verification Testing (BVT) is a crucial step in the software development lifecycle. It involves running a specific set of tests on every new build of a software product to ensure that the build is stable enough for further, more detailed testing. The primary goal of BVT is to verify that the core functionalities of the application are working correctly before the build is handed over to the broader test team. BVT helps to catch critical issues early, saving valuable time and effort […]
HTML, or HyperText Markup Language, is the foundational technology that powers the structure and layout of websites. Every web page you visit relies on HTML to organize its content, making it readable and accessible in web browsers. HTML uses tags as the basic building blocks to define various elements like headings, paragraphs, images, and links. Understanding these tags is essential for anyone aiming to create well-structured, user-friendly websites, whether a beginner or an experienced developer looking to refresh their knowledge. Web development often […]
SQL stands for Structured Query Language. It is a powerful language used to access and manipulate databases. SQL allows users to perform a variety of operations, such as inserting, deleting, altering, and updating records in a database. Since its standardization by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) in 1986, SQL has become the foundation for working with relational databases. One of the common challenges when working with databases involves managing dates and times. Storing, querying, and […]
C is a procedural, general-purpose programming language that is widely used in system and application development. Known for its performance and portability, C enables efficient manipulation of system-level resources and offers a wide range of functionalities such as recursion, structured programming, and lexical variable scoping. C supports static type systems, meaning variable types are known at compile time, which helps in creating robust and error-free code. The design of C allows programs to be written in a way that maps closely to machine […]
Every data professional approaches the task of retrieving information differently, depending on the specific needs of their analysis or application. SQL, or Structured Query Language, offers a range of tools that help users extract and manipulate data efficiently. One of the fundamental functions available in SQL for handling strings is the substring function. This function provides a powerful way to extract a specific set of characters from a larger string, allowing for precise data manipulation and retrieval. What Is the Substring Function in […]
Centering elements in CSS might seem straightforward at first glance, but it can be surprisingly tricky depending on the context. The main challenge comes from the variety of ways elements behave inside their containers and how different CSS properties interact with each other. Many developers find themselves confused or frustrated because a method that works for one type of content or layout might fail in another. Why Centering Is Not Always Simple The concept of “center alignment” is easy to understand: you want […]
Managing data effectively is critical in today’s data-driven world. Organizations collect vast amounts of data that need to be stored, updated, and sometimes removed. The process of managing this data includes handling additions, updates, and deletions within databases. Deleting data is a necessary operation when records become obsolete, incorrect, or irrelevant due to real-world changes. For example, if a store discontinues a product, its record must be removed from the inventory database to maintain accurate information. Data deletion must be carried out with […]
The Fibonacci series is one of the most famous sequences in mathematics and computer science. It starts simply but leads to fascinating patterns and wide applications. The sequence begins with the numbers 0 and 1. Every number following these two is calculated by summing the two numbers before it. The series looks like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, and continues infinitely. This simple rule creates a sequence with many interesting properties. Leonardo of Pisa, a mathematician […]
