A metadata repository is a software tool that stores descriptive information about the data model used to store and share metadata. Metadata repositories combine diagrams and text, enabling metadata integration and change. The metadata repository’s power lies with the easily accessible way people can view and navigate its contents. Other Definitions of Metadata Repositories Include: […]
What Is a Wide Column Database?
Wide column databases, or column family databases, refers to a category of NoSQL databases that works well for storing enormous amounts of data that can be collected. Its architecture uses persistent, sparse matrix, multi-dimensional mapping (row-value, column-value, and timestamp) in a tabular format meant for massive scalability (over and above the petabyte scale). Column family […]
What Is a Document Database?
Document databases refers to a category of NoSQL that represents data in a tree structure, where paths or branches connect data values or leaves. Frequently, document stores use XML and JSON formats stores. There are few practical limits to the number of paths, fields, values, or types of data that can be added to specific […]
What Is Data Science?
Data Science is a combination of scientific disciplines “to build predictive models that explore data content patterns,” according to the Data Management Body of Knowledge (DMBoK). Data Science, formerly known as applied statistics: “Integrates methods from mathematical, statistical, computer science, signal processing, probability modelling, pattern recognition machine learning, uncertainty modeling and data visualization towards gaining […]
What Is a Data Architect?
A data architect provides clear specifications, models, and definitions, translating a business’ Data Strategy into a Data Architecture and implementing this structure to align with an organization’s Data Governance. An architect is one who designs and advises on the construction of something. Data architects take an organization’s raw data and data assets and builds a […]
What Is Data Ethics?
Data Ethics describe a code of behavior, specifically what is right and wrong, encompassing the following: Data Handling: generation, recording, curation, processing, dissemination, sharing, and use. Algorithms: AI, artificial agents, machine learning, and robots. Corresponding Practices: responsible innovation, programming, hacking, and professional codes. Data Ethics build on the foundation provided by computer and information ethics, but […]
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. 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 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 […]
