Examples of a data integration and curation system are provided. The system may receive data extracting requirement related to a digital initiative and obtain digital initiative data associated with the same. The system may classify the digital initiative data into various data domains and extract metadata therefrom based on data analysis. The system may determine a word index including a plurality of words from a knowledge database. The plurality of words may be mapped with the data domains to identify a data anomaly in the digital initiative data. The system may determine an anomaly correction for resolving the data anomaly and update the plurality of data domains to include the anomaly correction. The system may identify a user parameter associated with the digital initiative. The system may associate the user parameter with the metadata to create user parameter data associated with the user parameter to generate a data extraction result.
