You must have heard these 2 terms. What are the differences?
Big data is a collection of data so large and moving so fast that it cannot be examined with standard technology tools. It’s an unstructured data.
Meta data refers to descriptive details about individual digital asset. Meta data provides granular information about a single file. It’s a structured data with preset column names in a database.
Big data has 4 dimensions:
- Volume: large volume of data
- Velocity: quickly moving data
- Variety: could be structured, unstructured, images, videos, anything
- Veracity: trust and integrity are a challenge
In my opinion, big data is more beneficial to help us predict consumer behaviors. However, it’s more difficult to manage and analyse. Not many company could manage it properly.
We are still struggling to manage metadata.
