Decision Support Task

A Decision Support Task is a support task that supports a decision making task.

• Context:
  • It can be solved by a Decision Support System.
  • It can involve an Analytical Processing Task (such as OLAP).
• Example(s):
  • a Domain-Specific Decision Support Task, such as: clinical decision support task or a legal decision support.
  • a Decision Support Benchmark Task.
  • …
• Counter-Example(s):
  • Predictive Modeling Task.
  • Data Logging Task.
  • Comprehension Task.
• See: Record Keeping Task, Auditing Task.

  • QUOTE: TPC-DS is the de-facto industry standard benchmark for measuring the performance of decision support solutions including, but not limited to, Big Data systems. The current version is v2. It models several generally applicable aspects of a decision support system, including queries and data maintenance. Although the underlying business model of TPC-DS is a retail product supplier, the database schema, data population, queries, data maintenance model and implementation rules have been designed to be broadly representative of modern decision support systems.

    This benchmark illustrates decision support systems that:

    • Examine large volumes of data
    • Give answers to real-world business questions
    • Execute SQL queries of various operational requirements and complexities (e.g., ad-hoc, reporting, iterative OLAP, data mining)
    • Are characterized by high CPU and IO load
    • Are periodically synchronized with source OLTP databases through database maintenance functions
    • Run on “Big Data” solutions, such as RDBMS as well as Hadoop/Spark based systems
