Explanation: The BigInsights Console accepts queries from HDFS_READ, HDFS_WRITE, and JAQL_SUBMIT user-defined functions that are run on the Netezza Performance Server
(NPS). With the Netezza Performance Server user-defined functions, you can communicate with BigInsights through an SQL statement. By using these user-defined functions, you can
read or write data to the BigInsights distributed file system and launch Jaql queries that run on BigInsights.

Explanation: In todays era of big data, technology is allowing us to consume more data and generate new insights for competitive advantage. It is mandatory to have
fast access to insight and to have the agility to quickly respond to rapidly evolving analytic requirements. At IBM, we recognize you need solutions to respond to these needs and
take your data warehouse architecture to the next level. Solutions that provide the speed, simplicity, scalability and analytic power to modernize your data warehouse and respond
to todays demands of big data.
IBM Netezza appliances are now part of IBM PureSystems - expert integrated systems with built in expertise, integration by design and a simplified user experience. Part of the
PureData family, the Netezza appliance is now known as the PureData System for Analytics. It has the same key design tenets of simplicity, speed, scalability and analytics power
that was fundamental to Netezza appliances.
With simple deployment, out-of-the-box optimization, no tuning and minimal on-going maintenance, the IBM PureData System for Analytics has the industrys fastest time-to-value and
lowest total-cost-of-ownership.

Explanation: In systems engineering and requirements engineering, a non-functional requirement (NFR) is a requirement that specifies criteria that can be used to judge
the operation of a system, rather than specific behaviors. They are contrasted with functional requirements that define specific behavior or functions. The plan for implementing
functional requirements is detailed in the system design. The plan for implementing non-functional requirements is detailed in the system architecture, because they are usually
Architecturally Significant Requirements.
Broadly, functional requirements define what a system is supposed to do and non-functional requirements define how a system is supposed to be. Functional requirements are usually
in the form of "system shall do
description input, output, process and control functional model or IPO Model. In contrast, non-functional requirements are in the form of "system shall be
an overall property of the system as a whole or of a particular aspect and not a specific function. The system's overall properties commonly mark the difference between whether
the development project has succeeded or failed.
Non-functional requirements are often called "quality attributes" of a system. Other terms for non-functional requirements are "qualities", "quality goals", "quality of service
requirements", "constraints" and "non-behavioral requirements". Informally these are sometimes called the "ilities", from attributes like stability and portability.
Qualities"that is non-functional requirements"can be divided into two main categories:
Execution qualities, such as safety, security and usability, which are observable during operation (at run time).
Evolution qualities, such as testability, maintainability, extensibility and scalability, which are embodied in the static structure of the system.

Question :
What is PIG?
1. Pig is a subset fo the Hadoop API for data processing
2. Pig is a part of the Apache Hadoop project that provides scripting language interface for data processing

Question : Which statement most accurately describes the relationship between MapReduce and Pig?
1. Pig programs rely on MapReduce but are extensible, allowing developers to do special-purpose processing not provided by MapReduce.
2. Pig provides no additional capabilities to MapReduce. Pig programs are executed as MapReduce jobs via the Pig interpreter.
