DESIGNER
- Target and Source Metadata.
- Here import from DB
MODELS
- New Model Folder
- Give any name , like Oracle i.e whatever the name you want.
- After giving the name you wont see anything while you expand.
- Now create new model ,
- Metadata taken from ORACLE DB here scott schema.
- Map the Logical schema name here.
- Write the description so that you will understand in future, why this Designer is created.
Reverse Engineering
- Types of object to reverse engineering.
Selective Reverse Engineering
- Difference between New Datastores & Existing Datastores. ( if you want to reimport the table again which the reverse engineering is done , that time you can enable the EXISTING DATASTORE )
- Click the Reverse Engineering here.
- See the difference carefully for " New Datastores & Existing Datastores "
It will overwrite the existing one , but here is the super question . If my table as 5 columns at first --> reverse engineering is done --> There is some update in the table where the column is reduced to 4 --> if I click the reverse engineering what will happen ? ANSWER is --> It will replace completely . Can I create multiple copies here ?
Create the Model for the target too like below.
PROJECTS
- New Projects --> Give any name.
- Once created , you will see
First Folder - Variables - Sequences - User Functions - Knowledge Module - Markers
- You can even create NEW FOLDERS also.
- Goto the MAPPINGS --> New Mappings --> Mapping Name.
- What is CREATE EMPTY DATASET ? It will create a EMPTY PANEL to drag and drop the source and target.
- Drag and drop the TARGET & SOURCE from the MODEL.
KNOWLEDGE MODULES
- Once the Target and Source are drag and dropped , now go to the KM.
- Select the KM.
- Here , Oracle to Oracle won't be there , so select SQL TO SQL as Oracle supports SQL.
- What is LKM & RKM , IKM ?
MAPPING
- Map the Source to Target in the Logical panel.
- Now goto PHYSICAL,source and target will be visible.
- Once you click the Default in the Target , select the LKM.
- LKM will create a TEMP table.
- FALSE means it will keep the TEMP date. Tell me will it consume more space in the target ?
- Keep an EYE ON THE INDEXES , if you need enable it.
- If the TARGET doesn't have the table , then enable this below options.
- Validate the mapping.
- RUN the Project.
- What is SIMULATION here ?
- Below option should be disabled , ( this is an option in the Oracle DB )
- Once the execution completed , go to Operation Tab.
OPERATION
- You can view the execution.
- Constrains --> Unique / Foreign keys.
- You can create NEW TASK also here , in future if you want to add.
QUESTIONS
- What is LKM & IKM ?
