The new operators are naturally evaluated in parallel and take advantage of hardware-optimized bitmap operations. In most scenarios, bit vector SQL functions combined with materialized views can provide significant performance improvements for queries with COUNT(DISTINCT) operations, which are common in data warehousing environments. You can construct bit vectors by further grouping on a larger set of GROUP BY keys than targeted queries, so that you can use one materialized view to rewrite multiple GROUP BY queries with COUNT(DISTINCT) expressions by using ROLLUP. The resulting bit vector can be materialized, such as in a materialized view. 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.

The Dual Senior overcomes this drawback by supporting two batches running simultaneously. With compost tumblers, users are restricted to working with one batch at a time. The Compost Wizard Dual Senior combines some of the greatest features in our tumblers to create a compact tumbler that does it all. The next generation of composting is now available.
