Design Experience

Talend Studio

// Talend generates native Java code
// Example: tMap transformation generates code like:
 
public void tMap_1Process(final tMap_1Struct tMap_1) throws Exception {
    // Input row processing
    row1Struct row1 = new row1Struct();
    row1.customer_id = tFileInputDelimited_1.customer_id;
    row1.name = tFileInputDelimited_1.name;
    row1.amount = tFileInputDelimited_1.amount;
 
    // Lookup
    row2Struct row2 = lookup_customer.get(row1.customer_id);
 
    // Transformation logic
    if (row2 != null) {
        out1Struct out1 = new out1Struct();
        out1.customer_id = row1.customer_id;
        out1.customer_name = row1.name;
        out1.segment = row2.segment;
        out1.total = row1.amount * (1 - row2.discount_rate);
        // Output
        tMap_1_Output1(out1);
    }
}
 
/*
 * Talend Design Characteristics:

 */

Informatica Designer

-- Informatica uses metadata-driven mappings
-- Transformation logic stored in repository
 
-- Example: Expression transformation
-- CUST_FULL_NAME = CONCAT(CONCAT(FIRST_NAME, ' '), LAST_NAME)
-- DISCOUNT_AMOUNT = ORDER_AMOUNT * DECODE(TIER,
--                     'GOLD', 0.20,
--                     'SILVER', 0.15,
--                     'BRONZE', 0.10,
--                     0.05)
-- FINAL_AMOUNT = ORDER_AMOUNT - DISCOUNT_AMOUNT
 
/*
 * Informatica Design Characteristics:
 * - Visual mapping designer (web and desktop)
 * - Metadata-driven (no code generation visible)
 * - Transformation Gallery with reusable logic
 * - Mapplets for modular design
 * - Parameter files for runtime configuration
 * - Workflow orchestration with dependencies
