Abstract Details

2022, Master of Computer Science, Miami University, Computer Science and Software Engineering.
NoSQL database systems are useful for managing large and diverse data sets associated with Big Data. Highly diverse data sets contain data with different structures, but often there are no readily available schemas describing the structures. The lack of a uniform structure for data may make it difficult to understand and query a database. Recent research and industry software tools extract some aspects of the structures inherent in a NoSQL database; most tools provide a schema that gives the union of attributes across all objects, termed a union schema. Some provide sample values for attributes. We present Schemalysis, a tool for analyzing and displaying the sub-schemas of a document NoSQL database along with example instances. The web application implements an algorithm that reads objects and detects individual sub-schemas of each document in a document database, as well as the database’s union schema. We also conduct three different case studies to validate the functionality of Schemalysis with real-world data and compare and contrast to existing tools for extracting schemas.
