A casino is implementing salesforce and is planning to build a customer 360 view for a customer who visits its resorts. The casino currently maintained the following systems that records customer activity:
1. Point of sales system: All purchases for a customer.
2. Salesforce: All customer service activity and sales activity for a customer.
3. Mobile app: All bookings, preferences and browser activity for a customer.
4. Marketing: All email, SMS and social campaigns for a customer.
Customer service agents using salesforce would like to view the activities from all system to provide supports to customers. The information has to be current and real time.
What strategy should the data architect implement to satisfy this requirement?
