When implementing a new application, most of the time an integration with one or several systems is required. This certainly was the case in most projects in which I've participated in the past. Some examples:

• Integration between the existing ERP system and Salesforce as a new CRM application
  As Symeta not only offers products & services to business operating units within Colruyt Group but also to customers outside of Colruyt Group, they wanted to improve the CRM to be able to better manage leads, accounts and opportunities. To meet the business requirements, Salesforce was introduced which had to be integrated with the existing ERP system, CERM.
• Integration between the legacy systems and a new PIM application
  Colruyt Group decided to make the switch from legacy systems to a new PIM application, STEP. However, as the existing mainframe modules could not be decommissioned, an integration was required.
• Integration between the existing ERP system and a new web-2-print application
  One of Symeta's customers requested a W2P module in which they can create sales orders from a set of predefined products in the catalogue. To enable planning and invoicing of these orders, an integration with the existing ERP system, CERM, was required.
• Integration between Salesforce a a MDM system and legacy applications
  Within Partena Professional, the decision was made to obtain employer data from an external data supplier and to mange this data within Salesforce / to switch data mastership from legacy to Salesforce. However, as several legacy applications still relied on this data to perform certain processes, an integration was set up between Salesforce as an MDM system and several legacy applications.

Setting up these integrations involved a number of steps such as:

• Analysing business, system and integration requirements
• Creating a datamodel for different applications and determining data lineage
• Creating integration & service specifications including data transformation rules
• Creating and executing test scenarios and test cases for system integration testing
• Data selection and migration
