Structured vs. Unstructured Data: The Rise of Data Anarchy

Data science and business analytics works
with both structured and unstructured data. Yet the future belongs to unstructured or semi-structured data from both internal and external sources.

Total Enterprise Data Growth 2005-2015





IDC estimates the volume of digital data will
grow 40% to 50% per year. By 2020, IDC predicts the number will have reached 40,000 EB, or 40 Zettabytes (ZB). The world’s information is doubling every two years. By 2020 the world will generate 50 times the amount of information and 75 times the number
of information containers.

The massive growth of unstructured or semi-structured
data is amazing and has implications for data warehouse / business intelligence / data analytics architecture and database design. The way we capture, store, analyze, and distribute data is transforming. New technologies like deduplication, compression, and
analysis tools are lowering costs.

Structured data gives names to each field
in a database and defines the relationships between the fields. Unstructured data is usually not stored in a relational database (as traditionally defined) where the data model is relevant to the meaning of the data.

.

The Internet of Things (equipping all objects
in the world with identifying devices), blogs, videos, social media, emails, notes from call centers, and all forms of human and computer to computer communications will soon start to produce massive amounts of unstructured or semi-structured data.

.

The trick is to create value by extracting
the right information from both internal and external data sources. That is what the science of data and art of business analytics needs to learn to extract from larger and larger sets of unstructured data.
