Spring Boot Banners

In this endpoint of internet, we’ll explore how to create a custom banner in a Spring Boot application.

Overview

When a Spring Boot application starts, it prints a banner, a visual representation, or text (often with ASCII graphics or branding information). The banner is a way to provide a more engaging and informative startup experience for developers and users such as the application name, version, or any other relevant data.

Definition

A transaction in DBMS is a finite sequence of database operations that is executed as one logical unit of work, meaning either all operations are performed successfully or none are performed.

-- Example for "logical unite of work"
Read(A)
A = A − 100
Write(A)
Read(B)
B = B + 100
Write(B)
Commit

A transaction must satisfy the ACID properties to ensure database correctness and consistency.

Key Points

• A transaction groups multiple database operations into a single logical task
• Partial execution is not allowed
• Failure of any operation causes the entire transaction to rollback
• Ensures reliability in concurrent and failure-prone environments

---

ACID Properties (Overview)

• Atomicity – All operations execute or none execute
• Consistency – Database remains in a valid state
• Isolation – Transactions do not interfere with each other
• Durability – Committed changes persist permanently

---

Schedule

A schedule is the execution order of operations of multiple transactions on the same database, possibly executed concurrently.
