Study Notes
Structured Data
- Typically organized in columns and rows, similar to spreadsheets and relational databases.
- Clear and defined data, easy to capture and analyze.
- Examples include name, address, contact number, date, and billing information.
- Benefits include understanding by programming languages and relatively quick manipulation.
Unstructured Data
- Estimated to account for around 80% of all data.
- Difficult to process or analyze using traditional methods due to the lack of internal identifiers for search functions.
- Includes text and multimedia content such as email, messages, documents, photos, videos, presentations, web pages, etc.
- Organizations increasingly focus on mining unstructured data to gain a competitive advantage.
Cloud Storage Solutions
- Unstructured Data: Cloud Storage is a good option for managing files, backups, logs, blobs, etc.
- Structured Data:
- For workloads with analytics needs: Cloud BigQuery and Cloud Bigtable.
- For relational databases:
- Traditional managed databases: CloudSQL (MySQL or PostgreSQL)
- Horizontally scalable and highly available databases: Cloud Spanner.
- Simple NoSQL option: Cloud Datastore
