Understanding Serverless Databases: Classic Serverless vs Neo-Serverless
The term “serverless database” has gained popularity with the rise of cloud computing and on-demand services, but it has a dual meaning depending on context.
In particular, databases can be “serverless” in either the traditional, client-side manner (e.g., SQLite’s model) or the cloud-native way often associated with managed databases.
This article explores these two approaches to serverless databases—classic serverless and neo-serverless—along with contrasting examples from other database models like client/server architectures.

The SINH() function in SQLite calculates the hyperbolic sine of a value. The hyperbolic sine is a mathematical function that can return any real number and grows exponentially as its input increases or decreases.
A Quick Look at SQLite’s LOG10() Function
The log10() function in SQLite is used to calculate the base-10 logarithm of a number. This function is part of SQLite’s built-in mathematical functions, and it returns the logarithmic value of the argument passed to it.
Understanding the ATAN2() Function in SQLite
The ATAN2() function in SQLite calculates the arc tangent (inverse tangent) of the ratio of two given numeric values, typically representing the y-coordinate and x-coordinate of a point.
Unlike ATAN(), which calculates the angle based only on a single tangent value, ATAN2() considers both the x and y values to determine the correct quadrant for the resulting angle.
A Quick Overview of the ATAN() Function in SQLite
The ATAN() function in SQLite calculates the arc tangent (inverse tangent) of a given numeric value. The result is the angle in radians whose tangent is the specified number.
Overview of the POWER() Function in SQLite
SQLite provides various mathematical functions out of the box, and one of them is the power() function (also available as pow()).
The power() function calculates the result of raising one number to the power of another. In other words, it performs an exponentiation operation. This function is particularly useful for mathematical operations where powers or exponents are required.
How ATANH() Works in SQLite
The ATANH() function in SQLite calculates the inverse hyperbolic tangent of a given numeric value. The result is the value whose hyperbolic tangent is the specified number.
Understanding the .changes Command in SQLite
The .changes dot command in SQLite is a helpful utility for developers working with databases, especially when tracking the number of rows affected by SQL statements like INSERT, UPDATE or DELETE.
When used in the SQLite command-line interface, .changes toggles an option that shows the count of modified rows after executing a command.
This article looks at how the .changes command works, how it can be enabled or disabled, and provides an example to illustrate how it works.
A Quick Look at EXP() in SQLite
The exp() function in SQLite calculates the exponential of a given number, where the base is the mathematical constant e (approximately 2.71828). In other words, it returns e raised to the power of x for a given input x.
This function can be useful in scientific and statistical calculations involving exponential growth, decay, and other natural logarithmic-based transformations.
