Introduction In machine learning, the data features are one of the parameters which affect the model's performance most. The data's features or variables should be informative and good enough to feed it to the machine learning algorithm, as it is noted that the model can perform best if even less amount of data is provided of good quality. The traditional machine learning algorithm performs better as it is fed with more data. Still, after some value or the quantity of the data, the model's performance becomes constant and does not increase. This is the point where the selection of the ... Read More
Introduction In database design, the Entity Relationship (ER) model is a powerful tool for representing the structure of a database. One important aspect of the ER model is the way it handles attributes and relationships between entities. In this article, we will explore the concepts of attributes and relationships in the ER model, and how they are used to represent the data in a database. We will also provide real-life examples, code examples, and diagrams to illustrate these concepts. Attributes in the ER Model In the ER model, an attribute is a characteristic or property of an entity that describes ... Read More
When it comes to deploying and managing applications in the cloud, AWS offers a range of services that can help you automate the process.

B*-Trees: An Optimized Data Structure for Fast Data Retrieval in C++ A B*-tree is a self-balancing tree data structure that is optimized for fast data retrieval. It is a variant of the B-tree, which is a tree data structure that is designed to keep its data sorted and balanced. A B-tree is characterized by the fact that it has a high degree of order, meaning that its nodes are kept sorted in a specific manner. A B*-tree is similar to a B-tree, but it is optimized for even better performance. This is achieved through the use of a number of ... Read More
A B+ tree in DBMS is a specialized version of a balanced tree, a type of tree data structure used in databases to store and retrieve data efficiently. Balanced trees are designed to maintain a roughly equal number of keys at each level, which helps to keep search times as low as possible. B+ trees are a popular choice for use in database management systems(DBMS) because they offer a number of benefits over other types of balanced trees, including faster search times and better space utilization. What are B+ Trees? A B+ tree is a self-balancing, ordered tree data structure ... Read More
The business-logic layer is a crucial component of a software application that handles the processing of data and implementation of business rules. It sits between the user interface (UI) layer, which is responsible for presenting data to the user, and the data access layer, which is responsible for storing and retrieving data from a database. The primary function of the business-logic layer is to process and validate user input, apply business rules, and prepare data for storage or presentation. It acts as an intermediary between the UI and data access layers, ensuring that data is properly formatted and meets the ... Read More
Introduction When it comes to creating cost functions, catalog information is a crucial piece of data that can be used to optimize the performance of a model. In this article, we will explore how catalog information can be used in cost functions, the different types of catalog information available, and how to implement this in your code. What is Catalog Information? Catalog information refers to data that describes the products or items that are being sold by a company. This information can include things like product names, descriptions, pricing, and images. This data is often stored in a database and ... Read More
In this TypeScript tutorial, we will learn to convert the string to uppercase. We need to convert every single alphabetic character to uppercase to convert the whole string uppercase by keeping the numbers and special characters as it is. As a beginner TypeScript programmer, maybe a question can arise in your mind what is the need to convert the string to uppercase? Here is the very straightforward answer. Have you ever used the search bar of any website, which shows different results when you search? If yes, search the uppercase and normal strings, which will return the search result. It ... Read More
Have you ever tried to delete the object properties in TypeScript? Then you definitely came across the ‘delete’ operator. In TypeScript, the delete operator only allows deleting the undefined, optional, or any object properties. Also, it returns the boolean values according to whether it deletes the property or not. Below, we will understand the different use cases of the delete operator in TypeScript via different examples. Using the Delete Operator to Delete the Object Properties The main use of the delete operator is to delete the optional properties of an object. We can use the delete keyword as an operator ...

In this tutorial, we will learn to round numbers in TypeScript. In TypeScript, the number data types can contain number values with decimal parts, and sometimes, we require to remove decimal part by rounding the number value. For example, if you want to show the progress of something in the application, and you are getting the decimal value of the progress, but you want to show the integer values only, then it is required to round the numbers. Here, we will learn 3 to 4 different methods to round the numbers. Using The Math.round() Method to Round a Number In ... Read More
