![]() The sample files for this example can be downloaded from the following two links: ![]() In the Specifications data source there is one row per specification, and each row contains the product code that the specification relates to. Example Configurationįor this example, we have imported two data sources: one containing a list of products, another containing specifications for those products. The configuration of the relationships is best described using a simple example. Select the ‘parent’ data source in the “ Combined Data” list before pressing the “ Add…” button in the Combined Data area.Drag the child data source on top of the ‘parent’ data source, or.To create a parent → child relationship between two data sources, either: ![]() ![]() by selecting the data source in the top list and using the “Add…” button in the Combined Data area.dragging and dropping the data source(s) from the Data Sources list to the Combined Data list, or.The relationships are defined using a series of simple logic statements.Ī hierarchy of data sources can be created by either: This enables you to defined parent/child data relationships. The Combined Data area allows you to define the relationships between the data sources – for example, how the data from one data source relates to another. To ensure this, the value in the “ Key Prefix” field will be prepended to the key field values imported from this data source the value entered in the “ Field Prefix” will be prepended to the field names imported. When importing data into the Combined Data Source, the key field values and field names need to be unique across all child data sources. Your existing Eas圜atalog data sources will be shown in the “ Data Source” popup. To import an existing data source, use the “ New…” button: Note that deleting a data source from this list will also remove any relationships that use it in the ‘Combined Data’ list. The data sources that have been imported into the Combined Data Source can be managed using this list. The default value – “ datasource” – will normally be correct, but should be changed if one of your child data source contains a field named “ datasource“. The name specified here must not appear in any of the child data sources. To track which child data source data was imported from, Eas圜atalog creates a field in the Combined data source using the name specified by the “ Data Source Field Name” field. Specify the name of the Combined Data Source, which must be a unique data source name. This dialog is split in to three main areas: The “ Combined Data Source Configuration” allows you to import the child data sources and specify how they related to each other. Creating a Combined Data SourceĬombined data sources are created using the File → New → Eas圜atalog Panel → New Combined Data Source menu option. Child data sources can be optionally synchronized with their source data when the Combined data source is updated. By specifying a series of simple rules that determine how data from one data source relates to data from another data source, you can quickly build complex data structures without having to write SQL.Ī Combined data source is used as a ‘parent’ for other ‘child’ data sources: the original child data sources remain independent of the combined data source. Anyhow I think I will likely order again from TPD as long as I am not in dire need of the part(s) in a hurry.Combined Data Sources in Eas圜atalog allow you to combine data from separate data sources into a single panel. I think being able to speak to someone directly would be very helpful but maybe this would add the the prices. Another thing which seemed to cause confusion was that I was trying to order parts for more than 1 vehicle in my family (so the overall shipping costs were shared) but this caused the staff to send clarification requests back which caused further delays to getting my order completed. I found the prices to be either fair or reasonable or good for genuine Toyota parts so this was good but of course shipping costs took some of the $ savings advantage away. IF i was in a hurry for the parts this would have been problematic for me. This required me to try to communicate via the chat line which I found the only ended up in referring any and all the questions I had to the staff (whom you cannot speak to directly) so would receive answers via my email but this took at least 24 hours or up to 48 hours to get a reply. Even trying to refine the search did not seem to help. I found the parts search function to be somewhat difficult to locate the part(s) I was looking for.
