Understand views and fields


In reports and extracts, a view is a group of related data fields.  When you build a report or extract, select the view which contains the fields you want to include in your report or extract. There are five different views: node, node classification, source, source classification and project item.

In this topic


 


Which view should I choose?

The view you choose when building a report or extract determines the information (fields) you can include.

Below is a summary of the available views including links to example reports.

View Use this view to... Report examples

Node Classification

Report on the classifications, attributes and attribute values used to describe the people, places and other cases in your project.

You can use this view to show the classification structure, or the demographic spread of classified nodes.

This view does not contain any coding information. If you want to report on coding at nodes, choose the Node view.

  • List all the values for an attribute—for example, list all the cities specified for the attribute ‘location’.

  • Count the number of nodes by attribute value—for example, the number of people assigned to each age group.

  • List the nodes grouped by attribute value for a selected attribute—for example, list the people in each age group, with a total for each age group. See example report.

Node

Report on the nodes in your project including sources they code, coding references, and any classifications assigned to them.

This view includes 'intersecting' nodes which is useful for reporting on how coding at two nodes coincides—for example see which 'cases' intersect selected themes.

This view also includes collections, which you could use to limit the scope of your reports.

  • List the sources that are coded at selected nodes, including the number of coding references.

  • List the ‘theme’ nodes and count the ‘cases’ that are coded at them.

  • List the case nodes along with the 'theme' nodes that intersect them. See example report.

Project item

Use this view to create reports about the structure of your project. Report on your project and the project items, including the types of project items and who created them.

  • List all the people who work on the project and how many items of each type they have created.

  • List the project items grouped by type including when they were last modified. See example report.

Source Classification

Report on the classifications that are used to describe your sources. You can create reports that show the classifications in your project or how your sources are classified.

This view does not contain any coding information. To report on coding in sources, choose the Source view.

  • List the classified sources and folder location grouped by classification.

  • Count the number of sources that belong to each classification—for example, the number of books, magazine articles and so on. See example report.

Source

Report on sources including which nodes code the sources. This view also includes collections, which you could use to limit the scope of your reports.

  • Display sources that belong to a set and show the nodes that code the sources.

  • For each source, display nodes in descending order of coverage. See example report.

Understand how to work with the fields in a 'view'

Based on your selected 'view', you can choose the fields you want to include in your report or extract. Each view consists of a number of tables that contain related fields.

cn_report_views.gif

You can select fields from one or more tables within the view to add to your report or extract. For example, if you want to report on the node classifications and attributes in your project, you could choose:

You could then specify group options to organize a report. Using the example above, you could group the classification names together, so that Person is displayed once, Place is displayed once and so on.  If you are using the Report Wizard, refer to Summary and group options  If you are using the Report Designer, refer to Report criteria .

Which fields should I choose?

NVivo provides a flexible approach to choosing the information you want to include on report. You can choose descriptive information based on an item's properties or more detailed information based on how an item relates to other items.

Experiment by combining fields to get the required result—for example, if you want to focus on interview respondents and their demographic attributes, choose the Node Classification view and choose a combination of the following fields:

NOTE  Some combinations of fields produce more meaningful and manageable results than others. For more information, refer to the sections below for each view.

Understand the Node Classification view

Combine the fields in the Node Classification view to check the status of the node classifications in your project. For example, to list all the values for each attribute, choose the following fields:

cn_report_tables_node_classification.gif

NOTE  For best results, select fields from either the red box or the blue box as shown in the diagram above.

Summary of tables and fields

Below is a summary of the tables and fields available in the Node Classification view:

Table Includes fields related to...

Classification

The node classifications (person, place and so on) that have been added to your project.

Classification.Attribute

The attributes (gender, age and so on) defined for the node classifications in your project.

Attribute.Attribute Value

Attribute values (male, 25-35 and so on) defined for the attributes in your project.

Classification.Node

The nodes that have been classified as a person, place or other 'case'.

Node.Attribute Value

The attribute values assigned to the people, places or other 'cases' in your project.

Understand the Node view

Combine the fields in the Node view to check the status of the nodes in your project. For example, to report on nodes and the sources coded at them, choose the following fields:

cn_report_tables_node.gif

NOTE

Summary of tables and fields

Below is a summary of the tables and fields available in the Node view:

Table

Includes fields related to...

Node

Nodes and their properties.

Node.Classification

Classifications (person, place and so on) used to describe the nodes in your project.

Intersecting Node.Classification

The classification of nodes where coding at one node intersects with coding at another.

Intersecting Node.Attribute Value
