Each column of a relational database has the same number of rows, but some of the fields have a null value or appear to be empty. In wide-column databases, empty rows simply do not exist for a particular column.
Anon-relational database, or NoSQL ("Not Only SQL"), is a type of database that models and stores data differently from relational databases. Instead of tables, non-relational databases model relationships in their own way. The fourNoSQL database typesare: Document. Key-value. Column-based....

Apache Kafka is an open-source, distributed event streaming platform designed forhigh-throughput, low-latency data processing. It allows you to publish, subscribe to, store, and process streams of records in real time. Kafka is apopular choice forbuilding real-time data pipelines and streaming ap...
We propose an approach that leverages two techniques – namely Natural Language Processing and Text Analysis – to automatically identify class comment types, i.e., the specific types of semantic information found in class comments. To the best of our knowledge, no previous work has provided a ...
