Questão 192

Questão
Relational Sink
Responda
  • The majority of enterprise IT systems use relational databases as their storage backends
  • However, the method of incorporating data analysis results from a Big Data solution into such systems by first exporting results as a delimited file and then importing into the relational database takes time, is error-prone and is not a scalable solution
  • An enterprise generally starts off or is already at the descriptive or diagnostic analytics maturity level and aims to move towards the predictive or predictive analytics maturity level
  • The ________ compound pattern represents a part of a Big Data solution environment capable of egressing high-volume, high-velocity and high-variety data out of the Big Data solution environment

Questão 193

Questão
Relational Sink
Responda
  • the ________ pattern can be applied for directly exporting processed data to a relational database, which requires the use of a relational data transfer engine
  • Instead of directly using the data transfer engine, it can be indirectly invoked via a productivity portal which normally denotes ad-hoc usage
  • The _________ compound pattern represents a fundamental solution evironment comprised of a processing ______ with data ingress, storage, processing and egress capabilities
  • Storing very large dataset where they are accessed by a number of users simultaneously can seriously affect the data access performance of the underlying database

Questão 194

Questão
Relational Sink
Responda
  • A workflow engine can be used to automate the whole process and to perform data export at regular intervals
  • The _________ pattern is associated with the data transfer engine (relational), storage device, processing engine, productivity portal and workflow engine mechanisms
  • The resulting architecture is known as the __________, which includes the architecture of the Big Data solution, any connected enterprise systems and integration components
  • a file data transfer engine is used directly or indirectly through the productivity portal for ad-hoc exports

Questão 195

Questão
File-based Sink
Responda
  • On some occasions, data analysis results from a Big Data solution need to be incorporated into enterprise IT systems that use proprietary storage technologies, such as an embedded database or ________ storage, rather than using a relational database and provide a ________ import method
  • Like the Relational Sink pattern, manual export from the Big Data platform and import into such systems is not a viable solution
  • The typical makeup of a __________ includes the storage layer, processing layer, analysis layer and visualization layer
  • _________, a framework for processing data, requires interaction via a general purpose programming language, such as java

Questão 196

Questão
File-based Sink
Responda
  • The ________ pattern can be applied to automatically export data from the Big Data platform as a delimited or a hierarchical file
  • a file data transfer engine is used directly or indirectly through the productivity portal for ad-hoc exports
  • ___________ - based processing platforms, such a Hadoop, do not require knowledge of data structure at load time.
  • As a result, data compression can be used to effectively increase the storage capacity of disk/memory space. In turn, this helps to reduce storage cost

Questão 197

Questão
File-based Sink
Responda
  • For regular exports, the file data transfer engine can be configurated via a workflow engine to run at regular intervals
  • Note that some level of post-processing may be required to put the file in the required format before it can be copied over the target location
  • The _________ pattern is associated with the data transfer engine (file), storage device, processing engine, productivity portal and workflow engine mechanisms
  • Although providing instantaneous results, setting up such as capability is not only complex but also expensive due to the reliance on memory-based storage (memory is more expensive that disk)

Questão 198

Questão
Automated Dataset Execution
Responda
  • The complete data processing cycle in Big Data environments consists of a number of activities, from data ingress to the computation of results and data egress
  • Furthermore, in a production environment, the complete cycle needs to be repeated over and over again
  • Instead of persisting the data to a disk-based storage device, _________ persists the data to a memory-based storage device
  • Based on the type and location of the data sources, this layer may consist of more than one data transfer engine mechanism

Questão 199

Questão
Automated Dataset Execution
Responda
  • Performing data processing activities manually is time-consuming and an inefficient use of development resources
  • To enable the automatic execution of data processing activities, the _________ pattern can be applied by implementing a workflow engine
  • However, if internal data is also integrated, the same solution will provide business-specific results
  • As a result, data compression can be used to effectively increase the storage capacity of disk/memory space. In turn, this helps to reduce storage cost

Questão 200

Questão
Automated Dataset Execution
Responda
  • the set of operations that need to be performed on the data is specified as a flowchart that is then automatically executed by the workflow engine at set intervals
  • This pattern can also be applied together with the Complex Logic Decomposition pattern to automate the execution of multiple processing jobs
  • The ________ pattern is associated with the workflow engine, data transfer engine, storage device, processing engine, query engine and productivity portal mechanisms
  • Note that some level of post-processing may be required to put the file in the required format before it can be copied over the target location
