✔✔Data security - ✔✔Definition:
Protecting stored data from destructive forces or unauthorized users.
✔✔Descriptive analytics - ✔✔Definition:
Analytical tools that describe what has happened.
✔✔Data mining - ✔✔Definition:
The use of analytical techniques for better understanding patterns and relationships that
exist in large data sets.
✔✔MapReduce - ✔✔Definition:
Programming model used within Hadoop that performs the two major steps for which it
is named: the map step and the reduce step. The map step divides the data into
manageable subsets and distributes it to the computers in the cluster for storing and
processing. The reduce step collects answers from the nodes and combines them into
an answer to the original problem.
✔✔Hadoop - ✔✔Definition:
An open-source programming environment that supports big data processing through
distributed storage and distributed processing on clusters of computers.
✔✔data query - ✔✔Definition:
A request for information with certain characteristics from a database.
✔✔advanced analytics - ✔✔Definition:
Predictive and prescriptive analytics.
✔✔data scientists - ✔✔Definition:
Analysts trained in both computer science and statistics who know how to effectively
process and analyze massive amounts of data.
