Ouvvi Queue Data Source

The Ouvvi Queue Data Source is a special read-only data provider that reads the context value from the Ouvvi project queue.

You would use this project in a traditional message based integration where an XML document is posted to an Ouvvi Project and the Ouvvi Data Source project at runtime receives this message as the data payload. Connected to a Data Source that supports Incremental Sync a single item can be quickly added or updated on the target system.

The Ouvvi Data Source is similar to the XML data provider except that the document is embedded in the Document property.

Document

The XML Document to process at runtime inside Ouvvi this document is replaced with the Ouvvi Queue Context value.

For example this provider might be used to update a single product item against a SQL database.

<NewDataSet>
  <Data>
    <ProductID>1</ProductID>
    <ProductName>Chai</ProductName>
    <SupplierID>1</SupplierID>
    <CategoryID>1</CategoryID>
    <QuantityPerUnit>10 boxes x 20 bags</QuantityPerUnit>
    <UnitPrice>10</UnitPrice>
    <UnitsInStock>0</UnitsInStock>
    <ReorderLevel>10</ReorderLevel>
    <Discontinued>false</Discontinued>
    <Updated>2015-12-08T12:02:13+00:00</Updated>
  </Data>
</NewDataSet>

XmlItemElementXPath

The XPath expression to the node item collection. i.e. //Data

Namespaces

If you need to register XML Namespaces for your document you can add XML Namespaces and prefixes in this collection.

Columns

Add to the Columns collection specifying the DataType, Name and the XPath Expression. XML XPath expressions are case-sensitive.

ID Column Name Column Price Column

Ouvvi

This project would be added to a new project in Ouvvi and then you would HTTP POST the XML document to the project Start API endpoint. If these projects are processing a single item then you can use Normal mode in Ouvvi so that they are executed in parallel to improve performance further.

Ouvvi Project

Multiple Ouvvi Project Steps will receive the same XML document so if this needs processing in multiple stages i.e. Invoice and InvoiceLines this is a good candidate.

Setting Save Failures property on the Ouvvi Step will write the message to the Ouvvi Failure Queue where the job can be restarted should and error occur.

Starting Project

To start your Ouvvi project POST your XML document to the Ouvvi project start Uri http://<ouvviuri>/api/projects/start/<projectid>

To do this with PowerShell 3.0 use the Invoke-RestMethod Cmdlet.

Invoke-RestMethod -Method POST -ContentType text/xml -InFile Product.xml -UseDefaultCredentials -Uri http://localhost:8080/api/projects/start/19

You can also post a Json document to Ouvvi and this will be converted into an XML document at runtime via Newtonsoft.Json.JsonConvert.DeserializeXmlNode method.
