What Is a Key-Value Database?

Key-value databases, also called key-value stores, are often considered the simplest type of NoSQL databases. Each unique identifier is stored as a key with its associated value. The value can be any sort of byte array, data structure, or binary large object (BLOB), and works well for storing enormous amounts of data. Windows Explorer and […]

What Is a Property Graph?

A property graph is a type of graph model where relationships not only are connections but also carry a name (type) and some properties.

What Is Canonical Data Modeling?

Canonical Data Modeling documents, using Data Modeling techniques, how messages or packets pass between different systems internally in the organization and across different company systems, to do e-business. Data sometimes vary, across systems, in their definitions. For example, a company may have defined “customer” for a data warehouse constructed 10 years ago and then characterized […]

What Is BASE?

BASE describes database processing germane to a NoSQL database, such as a data lake. An increasing number of data volumes and variability, according to DAMA DMBoK, spurred the BASE philosophy. Its popularity rose in 2008. BASE provides less assurance than ACID, but it scales very well and reacts well to rapid data changes. BASE construction […]
