All rights reserved. Are they the result of some MySQL peculiarity that allows storing data in a non-flat file? Four data models are presented and used: the graphical Entity-Relationship, the mathematical EMDM, the physical Relational, and … Data that will be stored in separate related tables in the relational database can be stored in a single table in a non-relational database. MySQL InnoDB supports clustered indexes, where the data is stored in the index instead of a flat file. To revisit our previous example, whereas a relational database would store data on a single camper across a series of related tables, a document database might store all the details for that camper in a single document. This method is known as "scaling out." Relational versus non-relational databases are more flexible because the data on the object isn’t limited to the same table. Creating a separate table for images or adding "image fields" to many tables? Now to fetch 86400 data points, it requires one random disk seek and sequential scan of 86400 data points.
