Aggregate functions perform mathematical calculations on a set of data, commonly used in statistical reporting and business to determine company health. Programming languages have specific rules for their use, and examples include adding, averaging, and sorting data. Database software uses structured query language (SQL) for real-time analytics.
In computer engineering, an aggregate function is a mathematical algorithm that returns a summary set of data. These functions perform simple mathematical calculations including counting, sorting, and averaging from a list of values. Data aggregation is commonly used in statistical reporting.
In business, an aggregate function can help executives determine a company’s health and profits. Most automated reporting programs include several aggregate functions that are used in standard accounting reports. These functions include sum, maximum, minimum and average algorithms.
Many software programs provide special methods for handling aggregate functions. These help developers with data conversion and mathematical calculations. Each programming language has specific rules about how aggregate functions are used within the software.
Adding a list of numbers is a simple math function and a good example of an aggregate function. This special function works add numeric values in a list of data. The add function in Microsoft® Excel® is a commonly used algorithm that performs addition.
Computing the average value of a set of numbers is another example of an aggregate function. The average function will typically return the mean or median value of a list of numbers. This special feature is typically used in business to help determine trends and anomalies.
Determining the minimum value from a list typically requires a complex mathematical algorithm. Most programming languages include an aggregate function that will return the minimum value from a set of data. This helps programs run more efficiently because the feature is optimized for performance.
A count function is a simple command that counts the number of lines in a set. This function is often used in spreadsheet software to define the number of values returned in the list. Count functions help determine the total number of values presented in a data set.
Many software programs use sorting algorithms that allow you to sort data in ascending or descending order. These algorithms use an aggregate function to determine the maximum and minimum value of a data set. This aggregation allows you to sort the data.
Database software is designed to manipulate and store a company’s information. This software uses functions aggregated through a tool called structured query language (SQL). SQL is a commonly used tool that provides real-time analytics to businesses.
