-As Data Science transitions from academia into industry, those norms influence organizations and applications. Professional Data Scientists now need teams of Data Engineers to move the data from production databases into centralized data warehouses and denormalized schemas that are more familiar, and ideally easier to work with. Large offline batch jobs are a typical integration point between Data Scientists and their Engineering counterparts who deal with online systems. As the systems grow more complex, additional specialized Machine Learning Engineers are required to optimize performance and scalability bottlenecks between databases, warehouses, models and applications.

Ultimately, previously working models start getting replaced by simpler solutions, so the business can continue to iterate. This is not a new phenomenon, see the fate of the Netflix Prize.

 Announcing the PostgresML Gym 🎉
 -------------------------------
 
-Instead of starting from the academic perspective that data is dead, PostgresML embraces the living and dynamic nature of data inside modern organizations. It's relational and growing in multiple dimensions.

-- Schemas are normalized for real time performance and correctness considerations
-- New rows are constantly added and updated, which form the incomplete features for a prediction
-- Denormalized datasets may grow to billions of rows, and terabytes of data
-- The data often spans multiple iterations of the schema, and software bugs can introduce outlier data

-We think it’s worth attempting to move the machine learning process and modern data architectures beyond the status quo. To that end, we’re building the PostgresML Gym to provide a test bed for real world ML experimentation in a Postgres database. Your personal gym will include the PostgresML dashboard and several tutorial notebooks to get you started.
