Implementing database triggers to capture schema change events and storing them in an audit table allows for automatic tracking of schema modifications. This ensures compliance requirements are met by maintaining a detailed audit trail. Utilizing transaction logs might not directly capture schema changes, and manually logging changes is prone to errors and lacks automation. Embedding version numbers in database objects doesn't inherently provide audit capabilities. Although maintaining a log of changes can be useful, it's more error-prone and manual compared to automated audit mechanisms.

OAuth is a protocol that allows third-party applications to obtain limited access to a user's data without exposing their credentials. Unlike traditional username/password authentication, OAuth involves token-based authentication where access tokens are issued to the third-party application.

In Go, the package name is not required when calling a function defined within the same package. Therefore, functionName(arguments) and not package.functionName(arguments) is the correct way to call a function defined within the same package. The period (.) before the function name is also not a valid syntax in Go for calling functions.

The delete function in Go is specifically designed to remove an entry from a map. It takes the map and the key as arguments and deletes the corresponding key-value pair.

In Go, the data type used to represent true or false values is 'bool'. Boolean data types can only have two values: true or false. They are commonly used for conditional statements and logical operations.

Anonymous functions in Go are functions without a specific identifier. They are declared using the func keyword without a name followed by the function body. These functions are useful for defining callbacks, deferred execution, or short-lived functions within a block of code.

You can make a copy of a slice in Go using the copy() function. The copy() function in Go copies elements from a source slice to a destination slice. It takes two arguments: the destination slice and the source slice. This allows you to create a new slice with the same elements as the original slice without affecting the original slice.

The main purpose of mocking in software testing is to verify the interaction or communication between different parts of a system. Mock objects are used to simulate the behavior of dependencies or external components, allowing developers to test the interactions without relying on the actual implementations of those components.

In Go, when defining a struct for JSON encoding, field tags are specified using struct tags. Struct tags are specially formatted metadata added in a struct field's definition, enclosed in backticks (`). These tags provide instructions or metadata about how the struct field should be encoded or decoded when using encoding/json package functions. They are used to customize the behavior of JSON encoding and decoding for individual struct fields.

The database/sql package in Go is commonly used for managing database connection pooling. It provides a generic interface for working with SQL databases and includes features for connection management, query execution, and result handling.
