Which stage of data-to-AI workflows is focused on transforming raw data into structured data for analysis?

The stage that is focused on transforming raw data into structured data for analysis is indeed Data Preparation. This phase is critical because it involves cleaning, organizing, and reshaping the data into a format that is suitable for analysis and modeling.

During Data Preparation, raw data is processed to handle issues such as missing values, inconsistencies, and irrelevant information. This step may also include techniques like normalization or standardization, feature engineering, and encoding categorical variables, all aimed at making the data more useful for building machine learning models. By preparing the data effectively, engineers ensure that the models can derive accurate insights and predictions based on clean and structured data.

Other stages, while essential in the overall workflow, do not focus specifically on this aspect. Data Storage is primarily concerned with where and how data is saved and retrieved. Data Ingestion refers to the process of collecting and importing data from various sources into a system. Machine Learning is the stage where algorithms are applied to the prepared data to make predictions or decisions based on the learned patterns.
