You need to create a centralized metadata connection to a database server for an application. Which steps should you take before building a Job that reads from that database? Choose 3 answers.
A.
Add a tCreateTable component to create a table in the database.
B.
Add a tMap component to handle and convert Db Types.
C.
Create Db Connections metadata to describe the database connection.
D.
Drag the Db Connections metadata onto the Designer to read from the database component.
E.
Retrieve the schemas from the database connection.
To establish a centralized metadata connection to a database server in Talend Studio, follow these steps before constructing a Job that reads from the database:
Create Db Connections Metadata to Describe the Database Connection (Option C):
In the Repository panel, right-click on "Metadata" and select "Create connection."
Fill in the necessary details such as database type, host, port, database name, username, and password.
Test the connection to ensure it is configured correctly.
Save the connection metadata for reuse across multiple Jobs.
Retrieve the Schemas from the Database Connection (Option E):
After creating the database connection metadata, expand it to view the available schemas.
Retrieve the required schemas by importing the table structures.
This step ensures that the schema definitions are centralized and can be reused in different Jobs.
Drag the Db Connections Metadata onto the Designer to Read from the Database Component (Option D):
In the Repository, locate the previously created database connection metadata.
Drag and drop the desired table or schema onto the Designer workspace.
Talend Studio will automatically create the appropriate input component (e.g., tDBInput) configured with the connection and schema details.
By following these steps, you ensure a centralized and consistent approach to managing database connections and schemas, promoting reusability and reducing configuration errors.
