In this project we have a look at two isolation levels: read committed and repeatable read. We will demonstrate their guarantees using different types of locks on these anomalies: nonrepeatable read, lost updates, and write skew.
NodeJs Database Concurrency explores strategies to handle multiples users in high concurrency. Here I explore NodeJs, Typescript, PostgreSql with different packages including pg and Prisma ORM.
This repository showcases applications developed for a practical work assignment on Transaction Control in the Master's in Computer Engineering program.
It is a repository created to learn advanced entity framework. All theoretically known knowledge has been tried practically through this pool. It was a different experience to deal with the isolation level issue with the entity framework in particular.
The following example shows how to override the default (READ COMMITTED) isolation level in a specific query to allow the user to retrieve the data without being locked on the requested data by another process that modifies it.
