ACCESS
 Beginning of databasing
Table
View
• Like Excel
spreadsheet
• Tightly defined
values
allowed
• Pulling info
from tables
using logic
• A lasting query
that is used to
populate
reports
Form
• Data input
Report
• Generates
reports
SQL
 Big Boy Access
 Same as Access without the bumpers and hand holding
 Real deal use in software world
 Can be used for maintenance and diagnosing software
back ends

HADOOP
 Virtualizes multiple computers/ servers to create a cloud computing
unit
 Hadoop Common – contains libraries and utilities needed by other Hadoop
modules.
 Hadoop Distributed File System (HDFS) – a distributed file-system that stores
data on commodity machines, providing very high aggregate bandwidth
across the cluster.
 Hadoop YARN – a resource-management platform responsible for
managing compute resources in clusters and using them for scheduling of
users' applications.
 Hadoop MapReduce – a programming model for large scale data
processing.
 Get started at: http://hadoop.apache.org/docs/current/
Analyze: SAS/ R/ SPSS/ Minitab
