A storage repository that holds a vast amount of raw data in its native format until it is needed. Any large data pool in which the schema and data requirements are not defined until the data is queried.

Data Scientist

A professional responsible for collecting, analyzing and interpreting large amounts of data to identify ways to help a business improve operations and gain a competitive edge over rivals. The demand for data science skills has grown significantly in recent years as companies look to glean useful information from the voluminous amounts of structured (tables, statistics) and unstructured data (images, tweets) that a large enterprise produces and collects -- collectively referred to as Big Data.

Digital Marketing

An umbrella term for all online marketing efforts. Businesses leverage digital channels such as Google search, social media, email, and their websites to connect with their current and prospective customers.

Distributed Ledgers

A distributed ledger is a database that is consensually shared and synchronized across network spread across multiple sites, institutions or geographies. It allows transactions to have public "witnesses," thereby making a cyberattack more difficult. The participant at each node of the network can access the recordings shared across that network and can own an identical copy of it. Further, any changes or additions made to the ledger are reflected and copied to all participants in a matter of seconds or minutes. Underlying the distributed ledger technology is the blockchain, which is the technology that underlies bitcoin.

DNS — Domain Naming Service

A hierarchical decentralized naming system for computers, services, or other resources connected to the Internet or a private network.

Domain Authority

A search engine ranking score developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). A Domain Authority score ranges from one to 100, with higher scores corresponding to a greater ability to rank. Generally speaking, sites with a very large number of high-quality external links (such as Wikipedia or Google.com) are at the top end of the Domain Authority scale, whereas small businesses and websites with fewer inbound links may have a much lower DA score. Brand new websites will always start with a Domain Authority score of one.
