The purpose of a PL/SQL function is generally used to compute and return a single value. This returned value may be a single scalar value (such as a number, date or character string) or a single collection (such as a nested table or array). User-defined functions supplement the built-in functions provided by Oracle Corporation. [6]
The observer design pattern is a behavioural pattern listed among the 23 well-known "Gang of Four" design patterns that address recurring design challenges in order to design flexible and reusable object-oriented software, yielding objects that are easier to implement, change, test and reuse.
Oracle Data Mining (ODM) is an option of Oracle Database Enterprise Edition. It contains several data mining and data analysis algorithms for classification, prediction, regression, associations, feature selection, anomaly detection, feature extraction, and specialized analytics.
In computer science, an operation, function or expression is said to have a side effect if it has any observable effect other than its primary effect of reading the value of its arguments and returning a value to the invoker of the operation.
Angular 2.0 was announced at the ng-Europe conference 22–23 October 2014. [16] On April 30, 2015, the Angular developers announced that Angular 2 moved from Alpha to Developer Preview. [17] Angular 2 moved to Beta in December 2015, [18] and the first release candidate was published in May 2016. [19] The final version was released on 14 ...
[2] [3] [4] As a consequence, only certain measurements can determine the value of an observable for some state of a quantum system. In classical mechanics, any measurement can be made to determine the value of an observable. The relation between the state of a quantum system and the value of an observable requires some linear algebra for its ...
Each trigger function is initially a stub, containing a default action or nothing. Programming Oracle Forms therefore generally consists of modifying the contents of these triggers in order to alter the default behavior. Some triggers, if provided by the programmer, replace the default action while others augment it.
For instance, documentation for an API function could note that its parameters cannot be null, that the function itself is not thread safe. [56] Because API documentation tends to be comprehensive, it is a challenge for writers to keep the documentation updated and for users to read it carefully, potentially yielding bugs.
