 The source material provides an introductory overview of SAP Core Data Services (CDS) , explaining why SAP developed this technology as a common, higher-level data model to be consumed across various technologies like OData and Business Intelligence.

Migrating SAP is a big job that needs careful planning.

Image
There are three ways to do it: Greenfield, Brownfield, and Bluefield. Each way has its good and bad points, so businesses need to think about things like what they need, how much money they have, and how long they have. They also need to think about how complicated their systems are and what they want to do in the future. If it's done right, the new system will work better and be easier to use. So, picking the right way to migrate SAP and making a good plan are super important. Let's look at each way: 📍 hashtag # Greenfield : Starting fresh, like building a new house on an empty lot. For example, a brand-new company decides to use SAP for the first time . 📍 hashtag # Brownfield : Updating what's already there, like renovating up an old house instead of building a new one. For instance, a company upgrades its existing SAP system to the latest version. 📍 hashtag # Bluefield : Mixing old and new, like adding a new room onto an existing house. For example, a company adds n...
