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. A property graph excels at showing connections among data scattered across diverse Data Architectures and data schemas. They provide a richer view on how data can be modeled over many different […]
Demystifying Data Architecture
Ludwig Mies van der Rohe said, “Architecture starts when you carefully put two bricks together”—and Data Architecture begins upon creating, storing, and putting two or more characters together, be they sets of records, emails, pictures, audio, video. This resonated well with initial thoughts about Data Architecture, as it is comprised of things, the functionality of […]
What Is a Data Silo?
Data silos have often had a negative connotation. They describe isolated data islands that appear or are discovered upon finding disjointed Data Management components. These include: Systems that cannot programmatically work with other systems because of older or incompatible code Fixed data that is controlled by one department or team but is cut off from […]
What Is ACID?
ACID properties characterize RDBMS (Relational Database Management System) database processing or a data warehouse. Originally coined in the early 1980s, according to DAMA DMBoK, the ACID philosophy consists of requirements for generating and maintaining reliable database transactions. ACID provides consistency before, during and after transactions through five properties: Atomic: Each task in a transaction succeeds […]
What Is Data-Driven?
The term data-driven describes a business state where data is used to power decision-making and other related activities efficiently, in real-time. For a business, reaching the data-driven state is like the difference between driving an automobile and traveling by horse. Data-driven businesses get to their destination faster and more efficiently. Data-driven characteristics include well-integrated data […]
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 […]
What Is Data Intelligence?
Just as a business must be effective in monitoring and managing finances, it also needs data intelligence capabilities to monitor and manage its data assets. Data intelligence, describes discovering, understanding, and governing data so that the business gets the maximum value in its investment of data with the minimum risk. This can also mean a […]
What Is a Chief Data Officer (CDO)?
A Chief Data Officer (CDO) helps bridge the gap between technology and business. This person evangelizes an enterprise-wide Data Management strategy at a senior level. The CDO leads Data Management initiatives, enabling an organization to leverage its data assets and gain a competitive advantage from them. A CDO tends to be part business strategist, adviser, […]
