INTERFACESLoad TRG_CUSTOMER

Some data we need are located in two flat files

INTERFACESLoad TRG_CUSTOMER. Define the topology

Let's define the topology for the flat files.Under the File technology there's already a data server named FILE_GENERIC.

Let's create a new physical schema

INTERFACESINTERFACESLoad TRG_CUSTOMER. Define the topology

1 – directory path

2 – Save 3 – Save

INTERFACESINTERFACESLoad TRG_CUSTOMER. Define the topology

Create a new logical schema

INTERFACESINTERFACESLoad TRG_CUSTOMER. Define the topology

Connect logical schema with physical schema, give a name, then save.

INTERFACESINTERFACESLoad TRG_CUSTOMER. Define the topology

Create a new model for the file technology. Fill all fields under Definition tab.

Save.

INTERFACESINTERFACESLoad TRG_CUSTOMER. Define Models and Datastores

Let's create a datastore for SRC_SALES_PERSON.txt

The file is fixed format and has no header.

INTERFACESINTERFACESLoad TRG_CUSTOMER. Define Models and Datastores

Set the fields in the Definition tab as shown

INTERFACESINTERFACESLoad TRG_CUSTOMER. Define Models and Datastores

Set the fields in the Files tab as shown.

Save your work

INTERFACESINTERFACESLoad TRG_CUSTOMER. Define Models and Datastores

By clicking the Reverse Engineer button now, we get a popup window showing the file content.

INTERFACESINTERFACESLoad TRG_CUSTOMER. Define Models and Datastores

Click at the end of each field on the ruler to delimit the bounds.

Click on each column then set its name and datatype.ATTENTION: Click on the field name, not on the ruler.Give to all fields the String datatype, for simplicity.Click OK then Save your work.

INTERFACESINTERFACESLoad TRG_CUSTOMER. Define Models and Datastores

INTERFACESINTERFACESLoad TRG_CUSTOMER

We're ready to design our interface now

INTERFACESINTERFACESLoad TRG_CUSTOMER

Drag all needed datastores in the interface editor, click Yes to perform the automatic mapping on the columns having the same name.

To perform the join between SRC_CUSTOMER.SALES_PERS_ID and SRC_SALES_PERSON.SALES_PERS_ID simply drag one columnover the other one.

INTERFACESINTERFACESLoad TRG_CUSTOMER

Click on each target field and set the mapping as shown.To set a source column as mapping in the target, simply drag the source column into the target mapping

INTERFACESINTERFACESLoad TRG_CUSTOMER

Click on Flow tab.Click here.As we can see, a Loading phase is required to store the file in a temporary table.To perform a Loading phase, ODI needs a Loading Knowledge Module (LKM).Of course it must be imported into the project.

We use this LKM

- Click here- Set the IKM- Save your work

INTERFACESINTERFACESLoad TRG_CUSTOMER

INTERFACESINTERFACESUpdate Dear in TRG_CUSTOMER

Create a new interface.Use TRG_CUSTOMER as source and as target datastoreDon't perform any automatic mapping

Drag CUST_ID into the target. Notice that it will be the update key (WHERE condition in update statement), since it's already a primary key

INTERFACESINTERFACESUpdate Dear in TRG_CUSTOMER

Click on DEAR column then use the editor to build the business rule

INTERFACESINTERFACESUpdate Dear in TRG_CUSTOMER

To get the column name in the editor, double click here or drag the column into the right pane.

Click OK

You can check the sintactic correctness of the statement by clicking here

INTERFACESINTERFACESUpdate Dear in TRG_CUSTOMER

Flag only the Update check box for the column DEAR and UPD_DATE.

INTERFACESINTERFACESUpdate Dear in TRG_CUSTOMER

INTERFACESINTERFACESUpdate Dear in TRG_CUSTOMER

Select the KMIKM Oracle Incleental Update we imported before and set the Flow Control to False.

Save your work.

INTERFACESINTERFACESLoad TRG_SALES

Finally we load the fact table

INTERFACESINTERFACESLoad TRG_SALES

Here's the interface.Notice that ODI automatically detects the GROUP BY clause, there's no need to specify it.
