BigQuery is a managed, serverless data warehouse product by Google, offering scalable analysis over large quantities of data. It is a Platform as a Service that supports querying using a dialect of SQL. It also has built-in machine learning capabilities. BigQuery was announced in May 2010 and made generally available in November 2011. [1]
Dremel is the query engine used in Google's BigQuery service. [1] Dremel is the inspiration for Apache Drill, [2] Apache Impala, [3] and Dremio, [4] an Apache licensed platform that includes a distributed SQL execution engine. In 2020, Dremel won the Test of Time award [5] at the VLDB 2020 conference, recognizing the innovations it pioneered. [6]
Given describes the preconditions and initial state before the start of a test and allows for any pre-test setup that may occur. When describes actions taken by a user during a test. Then describes the outcome resulting from actions taken in the when clause. The Given-When-Then was proposed by Dan North in 2006, as part of behavior-driven ...
In such cases, DbC makes the supplier's job easier. Design by contract also defines criteria for correctness for a software module: If the class invariant AND precondition are true before a supplier is called by a client, then the invariant AND the postcondition will be true after the service has been completed.
In computer programming, a precondition is a condition or predicate that must always be true just prior to the execution of some section of code or before an operation in a formal specification. If a precondition is violated, the effect of the section of code becomes undefined and thus may or may not carry out its intended work.
Google Cloud Platform is a part [8] of Google Cloud, which includes the Google Cloud Platform public cloud infrastructure, as well as Google Workspace (G Suite), enterprise versions of Android and ChromeOS, and application programming interfaces (APIs) for machine learning and enterprise mapping services.
