Sourcing data

Data sourcing is one of the most preliminary steps in the life cycle of data. It includes activities such as data acquisition, cleaning, and organization. The following is a list of the specific activities that it involves:

  • Raw data delivery—push model versus pull (extract) model
  • Handling a variety of data formats (CSV, JSON, XML)
  • Detecting errors in the data that is delivered
  • Removing bad data
  • Data enrichment—filling the gaps in the data
  • Combining data with other datasets
  • Defining a data model
  • Transforming the raw data model into the defined model
  • Storing the data

Data formats

By its very nature, there is a wide variety of raw data. There are a variety of systems generating raw data for a variety...
