Have you had experience with transaction management in databases or systems?

Yes, transaction management is an important part of working with databases, especially to ensure data integrity.

In Node.js, libraries such as Sequelize, TypeORM, or direct drivers (e.g., for PostgreSQL) are commonly used for database operations.

An example of managing a transaction using async/await and the Sequelize library:

const { sequelize } = require('./models');

async function performTransaction() {
  const t = await sequelize.transaction();
  try {
    await User.create({ name: 'John' }, { transaction: t });
    await Order.create({ userId: 1, total: 100 }, { transaction: t });
    await t.commit();
  } catch (error) {
    await t.rollback();
    throw error;
  }
}

Here, all operations within the transaction either succeed together or, in case of an error, are rolled back, preventing partial data updates.
