The upcoming talk on data modeling for unstructured or semi-structured data will explore the promises and challenges of using NoSQL databases, which offer agility and schema-less data storage. While NoSQL databases allow for easy storage of unstructured data, structuring is necessary for data utilization. The discussion will cover the differences between structured, unstructured, and semi-structured data, highlighting that while structured data requires predefined schemas, schemaless systems like key/value stores allow for flexible data storage. Semi-structured data, such as JSON and XML, provides implicit schemas with flexible field addition. The talk will address the practical aspects of writing, reading, and mapping data in these systems, using Couchbase as a case study to illustrate how data is structured and queried in distributed environments.
