When working with databases in software development, you often need to store, retrieve, update, and delete data. Traditionally, this involves writing SQL queries, which can be time-consuming and error-prone, especially in complex applications. Object-Relational Mappers, or ORMs, provide a solution to this by simplifying how you interact with databases. In this article, we'll explore what ORMs are, why they are useful, and when to use them. We'll also look at some popular ORM libraries in the .NET ecosystem, along with their pros and cons. What is an ORM? An Object-Relational Mapper (ORM) is a tool that allows developers to interact…

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, productivity, programming, software, tutorial

Problem description & analysis: In the Excel table below, the 1st column is the category; columns from the 2nd to the 42nd are parallel columns of data items (below only shows some of the columns), where there are two types of values – X and null. Occasionally, there are duplicate values in a column under the same category. Task: Group rows and combine values in each column in each group; only display one of the duplicate values if there are any. Solution: Use SPL XLL to do this: =spl("=?.group(~1).(g=~,(r1=~1).(g.(~(r1.#)).ifn()))",A2:E11) Enter fullscreen mode Exit fullscreen mode As shown in the picture…

Understanding and Implementing Static Arrays

stp2y0 CommentsNewscoding, community, cpp, development, engineering, inclusive, programming, software, tutorial

Important Takeaways Arrays allow us to keep track of lists of data of the same type (e.g., a list of numbers, strings, chars, etc.). There are two types of arrays: static and dynamic. This article focuses on static arrays. Static arrays require knowing the size at compile time, while dynamic arrays allow setting the size at runtime. Arrays can have any number of dimensions (1D, 2D, 3D, etc.), and each dimension can have any size, limited by the computer’s memory. For loops are the most appropriate structure to iterate over an array. Note that array indexes start at 0, not…

stp2y0 CommentsNewsbeginners, coding, community, datascience, development, engineering, inclusive, programming, python, software

What is EDA(Exploratory Data Analysis)? It refers to the critical process of performing initial investigations on data so as to discover patterns,to spot anomalies,to test hypothesis and to check assumptions with the help of summary statistics and graphical representations. EDA makes it easier for data scientists to find patterns, identify anomalies, test hypotheses, and verify assumptions by assisting in the best way to alter data sources to achieve the answers they require. EDA offers a better knowledge of data set variables and the interactions between them and is mainly used to examine what data might disclose beyond the formal modelling…

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, javascript, programming, software, webdev

Originally published on Makemychance.com The define() keyword is a fundamental concept in JavaScript programming. It is used to define a new module, which can be imported and used in other parts of the program. The define() keyword is part of the Asynchronous Module Definition (AMD) API, which is used to load modules asynchronously in the browser. When a module is defined using the define() keyword, it is given a name and a list of dependencies. The dependencies are other modules that this module requires in order to function correctly. When the module is loaded, the dependencies are loaded first, and…
