Explanation:
Big data refers to huge collections of data that are difficult to process, analyze, and manage using conventional data tools. It is a core component of the 3rd platform, which also includes cloud computing, mobile devices, and social networking. The five Vs of big data are high volume, high velocity, diversified variety, unknown veracity, and low-density value. Although SQL and relational databases can be used for big datasets, a collection of alternative tools referred to as NoSQL has become popular. These tools work well when databases scale out (horizontally) and when databases are broken into subsets called shards. Modern database tools also handle dynamic scaling as devices are added when additional capacity is required. NoSQL tools are sometimes said to create schema-less databases, but they usually have some type of structure, though it may be more flexible than the relational model. A key-value data model provides each data element with a key. A column-oriented data model makes it easy to access data stored in similar fields, rather than in individual records. Two very popular NoSQL tools include Hadoop, which is a big data file system, and MapReduce which sends processing logic to the data, rather than bringing the data to the computer that performs the processing.
Answer: Automated testing is testing of the software by the means of automation by using special tools .These software tools are responsible for the testing of the execution process , functioning and comparing the achieved result with actual result.
It is helps in achieving the accuracy as compared with manual testing and also also function without any human interruption.It produces the test scripts that can be re-used.
The requirements are mainly written in a feature style notation, using some state charts,
context diagrams and other techniques to describe certain parts of the system. See, for
example, Software Requirements - Styles and Techniques [Lauesen00].
The functional requirements are divided into four sections. The three modules in figure 1
are developed by separate groups, each responsible for unit testing. All requirements for
the taxi, central and communication link component are written in a feature style notation.
In addition, a special part of the taxi component is the positioning system. This is dealt
with separately since there are special requirements present on this component.
The functional requirements consist of four sections: Taxi (3.1), Central (3.2), Communication
link (3.3) and Positioning system (3.4).
