Big Data

large amounts of structured and unstructured data that can potentially be mined, examined, and used by organizations.

Data Processing

converting information that can be understood by a computer

Useable Data

Useful Data

Data Collection

gathering and measuring information on targeted variables in order to answer questions and evaluate outcomes

Collaboration

Structured Data

data that is organized in some fashion - utilizes less storage space

Data Set

Relational Database

Data Storage

the retention and retrieval of data

Screen Scraping

Indexing

the specific organization and method of keeping track of data

Filter Bubble

limiting a user's perspective by having an algorithm selectively determine what type of information a user would like to see based on past search history and behavior.

Privacy Concerns

digitization of personal data means your data is now easier to reproduce, share, sell and access.

Utility

the measurement of usefulness - example: sharing personal digital data in order to receive something of value in return.

Cache

a memory location to store active data temporarily to shorten data access times and reduce latency.
