Explanation: Annotation Query Language (AQL) is a language for building extractors that extract structured information from unstructured or semistructured text. AQL is
the primary method of creating new extractors in the InfoSphere BigInsights Text Analytics component.
The syntax of AQL is similar to that of Structured Query Language (SQL), but with several important differences:
AQL is case-sensitive.
AQL allows, but does not require, regular expressions to be expressed in Perl syntax. For example, /regex/ instead of regex.
AQL does not currently support advanced SQL features like correlated subqueries and recursive queries.
AQL has a new statement type, extract, that is not present in SQL.
AQL does not allow keywords as view, column, or function names.

Explanation: Views (MapReduce) for Cloudant

Views are used to obtain data stored within a database. Views are written using Javascript functions.

Views are mechanisms for working with document content in databases. A view can selectively filter documents. It can speed up searching for content. It can be used to 'pre-process'
the results before they are returned to the client.

Views are simply Javascript functions, defined within the view field of a design document. When you use a view, or more accurately when you perform a query using your view, the
system applies the Javascript function to each and every document in the database. Views can be complex. You might choose to define a collection of Javascript functions to create
the overall view required.





Question : Cloudant is a graph database ?
: Cloudant is a graph database ?
1. True
2. False

Correct Answer : Get Lastest Questions and Answer :
Explanation: IBM Cloudant is a managed NoSQL JSON database service built to ensure that the flow of data between an application and its database remains uninterrupted
and highly performant. Developers are then free to build more, grow more and sleep more.

IBM Graph is an easy-to-use, fully managed graph database service for storing, querying, and visualizing data points, their connections, and properties. IBM Graph is based on the
Apache TinkerPop stack for building high-performance graph applications. This means that the service provides you with a set of simplified HTTP APIs, an Apache TinkerPop v3
compatible API, and the full Apache TinkerPop v3 query language. The service gives you flexibility and capabilities, based on a familiar environment. Using the Bluemix dashboard,
you can bind IBM Graph to your applications easily.
