Continue ReadingIn SQL Server Analysis Services (SSAS), a Data Source defines how SSAS connects to a relational database. It includes the connection string and authentication credentials, allowing the SSAS engine to retrieve data for use in cubes, dimensions, and data mining models. These data sources are critical because they serve as the pipeline through which raw […]
Continue ReadingWindow functions in SQL Server offer a powerful way to perform calculations across a set of rows that are related to the current row. Unlike aggregate functions, which reduce the number of rows returned by summarizing data, window functions preserve the number of rows and allow the user to derive metrics for individual rows within […]
Continue ReadingSQL injection is one of the most critical and common security vulnerabilities in modern web applications. It arises when untrusted data from a user is sent to an interpreter as part of a command or query. The main issue occurs when this data is not properly validated or sanitized, allowing an attacker to manipulate the […]
Continue ReadingThe concept of average is foundational in mathematics, statistics, and data analysis. Within the realm of databases, calculating averages helps summarize vast sets of numeric data into a single, interpretable value. SQL, as a structured query language designed for managing and retrieving data in relational databases, provides built-in support for this operation through the AVG […]
Continue ReadingCouchbase is a modern NoSQL database designed to deliver high performance, scalability, and flexibility through a memory-first, distributed architecture. Unlike traditional relational databases that rely on rigid schemas and centralized storage, Couchbase embraces a decentralized approach. This architecture is built to support real-time applications by offering fast access to data and fault tolerance across large-scale […]
Continue ReadingIn real-world applications, data is rarely stored in a single table. Relational databases are designed to organize data across multiple tables to reduce redundancy and improve data integrity. This model allows you to maintain separate tables for customers, orders, employees, products, and other entities, and relate them using keys like customer IDs or employee IDs. […]
Continue ReadingIndexing is a fundamental concept in data analysis and reporting, particularly when working with tools like Power BI and SQL. In Power BI, indexing refers to the process of assigning a unique sequence or rank to rows within defined categories or groups. This is especially useful for ranking, sorting, or organizing data by measures such […]
Continue ReadingThe SQL SUM() function is one of the key aggregate functions used in database querying to calculate the total sum of values within a numeric column. This function takes multiple numeric values from the rows of a database table and adds them together, returning a single, consolidated result. It is particularly useful in scenarios that […]
