Example: Master and sales catalogs

We can insert, replace, or delete the master and sales catalog using the Data Load utility at the same time. These examples use a load file to demonstrate how to insert, replace, or delete the master and sales catalog.

This example uses a CSV file to demonstrate how to insert, replace, or delete your data. We can also create and use an XML formatted file to insert, replace, or delete your data. If you choose to create and use an XML formatted file, ensure that your XML elements use the same names as are used for CSV column names.

CSV column and XML element definitions

Identifier

(Required, String) The catalog identifier. This field cannot be null in Insert and it must be unique. In Replace or Delete, either this field or the CatalogUniqueId is required.

CatalogUniqueId

(Required, BigInt) The internal unique reference number of the catalog. In Replace or Delete, either this field or the Identifier is required.

Name

(String) The language-specific display name of this catalog.

Description

(String) A language-specific description of this catalog.

ShortDescription

(String) A language-specific short description of this catalog.

LongDescription

(String) A language-specific long description of this catalog.

Thumbnail

(String) The language-specific thumbnail image path of this catalog. For example, images/G1.jpg.

FullImage

(String) The language-specific full image path of this catalog. For example, images/G1.jpg.

MasterCatalog

(Boolean) A flag indicating whether the catalog is a master catalog. Default is false. Any value other than true automatically defaults to false.

Delete

(String) A flag indicating whether to delete. Specify 1 to delete the row.

CSV file with sample catalog data

Insert or replace In this example, you insert four new catalog data. The file contains sample master and sales catalog data. Each column is delimited by a comma. CSV file with sample catalog data

Delete In this example, the first three rows of data are deleted, and the fourth row replaces an existing data. Each column is delimited by a comma. CSV file with sample catalog data to be deleted or replaced

Mapping data

The following code snippet from the catalog loader configuration file demonstrates how to map each value to a business object logical schema path.

<_config:DataMapping>
	<_config:mapping xpath="CatalogIdentifier/ExternalIdentifier/Identifier" value="Identifier" valueFrom="InputData"/>
	<_config:mapping xpath="CatalogIdentifier/UniqueID" value="CatalogUniqueId" valueFrom="InputData"/>
	<_config:mapping xpath="primary" value="MasterCatalog" valueFrom="InputData" />
	<_config:mapping xpath="Attributes/description" value="Description" valueFrom="InputData" />
	<_config:mapping xpath="Description[0]/Name" value="Name" valueFrom="InputData" />
	<_config:mapping xpath="Description[0]/ShortDescription" value="ShortDescription" valueFrom="InputData" />
	<_config:mapping xpath="Description[0]/LongDescription" value="LongDescription" valueFrom="InputData" />
	<_config:mapping xpath="Description[0]/Thumbnail" value="Thumbnail" valueFrom="InputData" />
	<_config:mapping xpath="Description[0]/FullImage" value="FullImage" valueFrom="InputData" />
	<_config:mapping xpath="" value="Delete" deleteValue="1"/>
</_config:DataMapping> 

If you perform an insert or replace operation, do not specify the "Delete" column in the CSV file or we can leave the "Delete" column empty.

Business object mediator

The mediator class name is CatalogMediator. To initialize attribute dictionary for the store, see Initializing the attribute dictionary.

Note: When we use a mediator that is provided with WebSphere Commerce with the Data Load utility, the utility assumes that we are loading data for all columns for a business object. To update the data in only specific columns, configure a column exclusion list for the load process. A column exclusion list causes the Data Load utility to ignore specific columns during the load operation. If you do not use a column exclusion list, the utility updates all columns in the row of a database table row when the utility updates the row. If no value is set in the input file, the utility can replace the existing column value with a default value or set the value to be null. See Configure a column exclusion list.
