LLBLGen Pro Overview

🔍 What is LLBLGen Pro?

LLBLGen Pro is a simple tool that helps computer programmers create and organize data simply and quickly. It’s like a smart helper that connects a computer’s data (called databases) to the programs developers write. Normally, working with databases can be tricky, but LLBLGen Pro makes it easier by automatically organizing data and turning it into a format that’s easier to use in programs.

LLBLGen Pro, you can build something called an “entity model.” This model is a simple map showing how a program’s data is organized.
