To compute COUNT(DISTINCT) for numeric expressions, you can create a bit vector representation of the expressions and aggregate them before the final bit count. Use new bit vector SQL operators to speed up COUNT DISTINCT operations within a SQL query. You can also use these modules with calendars, Oracle JET Data Visualization components (JET charts), trees, and PL/SQL processes. Web Source Modules are the basis for all report types, such as interactive reports and classic reports, but not interactive grid regions. You can use post-processing SQL to apply functions, aggregations, or join with local tables. Modules also include post-processing SQL, which modifies the data being processed by the Oracle Application Express component. A module can contain one or many Web Source Operations, which are the references to a concrete external web service. Web Source Modules store additional metadata about how to parse response data and map it as a virtual table with rows and columns. The new Web Source Modules are highly declarative because they use discovery to understand and define the incoming structure of the web service. Defining such services was manual, time consuming, and error prone. In earlier Oracle Application Express releases, you could define Simple Object Access Protocol (SOAP) and REST web services and then utilize them within limited Oracle Application Express components. Web Source Modules provide a declarative method to define references to external Representational State Transfer (REST) APIs and generic JSON data feeds. References can also scale significantly better since ORDS utilizes a connection pool on the remote database. By contrast, REST enabled SQL references are defined at the Oracle Application Express workspace-level, and work with JSON over HTTP and HTTPS, which makes them easy to use in cloud environments or over the internet. References can also be used with calendars, Oracle JET Data Visualization components (JET charts), trees, and PL/SQL processes.Įach SQL statement defines Oracle Database links and work over SQL*Net (or over the internet in cloud environments), and must open a session within the remote database for each SQL or PL/SQL executed. REST enabled SQL references are used as the basis for all report types, such as interactive reports and classic reports, but not interactive grid regions. The JSON object contains result set metadata, the result data, and pagination details. Oracle Application Express passes the SQL or PL/SQL query to ORDS over REST returning a self-describing JavaScript Object Notation (JSON) response. These codes are random, encrypted, and are deleted after 14 days.You can easily create REST enabled SQL references by defining a name, the endpoint URL, and authentication information within shared components. If someone later reports a positive test result, the app sends an anonymous alert to anyone who may be at risk. Those codes cannot be used by the NHS, government or anyone to identify who you are, or who you’ve spent time with. Does the app send my number to other phones?Īs you come into contact with other app users, your phones automatically exchange random codes which tell the app if you have been near anyone for more than 15 minutes and at a distance of less than two metres. Any data shared with the app is only held on your phone, so if you decide to delete the app (which you can do at any time), all the data is deleted as well. The app protects privacy as it uses Apple and Google’s proven Bluetooth technology, designed so that nobody will know who or where you are. The app is tracking the spread of the virus, not the movements or locations of app users. The app doesn’t need to know WHO anyone is, or WHERE they are.
