Candidate sets are a fundamental concept of function calculation in PhixFlow.

Every time a function calculation is carried out, all the required input data is brought together and organised into sets of data - one set for each Key group.

The Key groups are worked out using the Pipe Grouping Attributes defined on input Pipe for each Streamtable.

A generic term for a 9050674641, a 9050674641, or an 9050674641modelling object that loads data. This can be a file, data from a database, or data from a external site.

A context menu appears above each 9050674641 when the user hovers over it in a model view. This menu shows all of the actions that can be performed on that element.

In many places on the PhixFlow interface you can:

• hover your mouse pointer
• right-click

to display a popup menu with more options.

A CSV (comma-separated variable) file is a plain text file where each line in the file consists of a number of fields separated by commas ','. If fields may contain spaces, commas or double quotes, they should be enclosed in double quotes '"'. A double quote may be represented by 2 double quotes.

A CSV file is always encoded using a specific character set. On Windows this is typically Cp1282, and on Unix/Linux US7ASCII, though the following are sometimes used: UTF-8, UTF-16, ISO-8859-1.

A CSV file typically has an extension '.csv'.

A CSV file can be created directly in a plain text editor (e.g. Wordpad/Notepad), in Excel (by saving as a CSV), or by some other application.

Whenever an analysis model is run it will carry out a number of tasks e.g. read a number of files, generate a number of stream setsrecordsets, export a number of files. It is possible to configure an analysis model so that in a single analysis session it will actually run several times. When a model is configured in this way, each time it runs is termed a 'cycle' and all of the items processed or generated during that cycle (i.e. the files processed, stream sets  recordsets created, files exported etc) are flagged with the cycle number. This cycle number is visible in the Log File for that analysis run on each of the relevant tabs showing files and stream sets and recordsets processed.

The most common reason for configuring a model in this way is to allow a number of files to be processed in a single analysis session but to have the results from each file saved in a separate stream setrecordset. In this way, whenever a file fails to process the user can simply rollback the stream sets the recordsets associated with that file rather than rolling back all of the stream sets the recordsets associated with all of the files for the whole analysis session.

To achieve this, a model is configured with a push pipe from the final stream table in the model pointing back to itself. This push pipe is then given positive offsets. The file collector at the start of the model is then configured to process a single file at a time. When this model is run the file collector will read in one file, process it to create a stream set a recordsets (or a chain of stream sets of recordsets if there are several streams tables in the model) and will flag the file processed, the stream sets the recordsets generated and any associated output files with the cycle number 1. When the last stream table in the model has finished producing its stream set its recordset it will send a notification to itself down the push pipe. This notification (because of the positive offsets) will be taken as a signal to create another stream set another recordsets which will effectively cause the whole model to run again. This second run of the model will be deemed to be cycle 2 and all files processed, stream sets  recordsets produced or files output will be flagged with this cycle number.

When later viewing the log files the user can see which items were processed in which cycle and can choose how many cycles to roll back. In the case where the last file processed was unsuccessful the user can therefore choose to only roll back the last cycle.

A Directed Pipe is used as a secondary input to a Merge StreamTable.

Primary Pipes to a Merge are implemented by reading all input records from all Primary Pipes in a single operation, ordered by the Group-By fields. The primary pipes determine the key values of the Candidate Sets that will be generated.

A Directed pipe is implemented after the Primary Pipes have run, by reading records matching each Candidate Set grouping key in turn. This can result in a significant performance improvement in certain circumstances.

A Pipe can be marked as a Directed Pipe on the Pipe Details / Advanced tab.

When parsing an XML response, the XPath on an 9050674641 HTTP collector determines the node in the XML response that will cause an output record to be generated. In general, XML node names are relative to namespaces, and are referred to by namespace aliases. An XPath can use any XML Namespace alias defined by the 9050674641 HTTP datasource linked to the 9050674641 HTTP collector.

An XPath expression on an 9050674641 HTTP collector determines the node in the XML response that will cause an output record to be generated.

An XPath is a '/'-separated list of node names.

If any of the node names in the XPath use non-default namespaces, these may be defined in 9050674641XML namespace.
