Aldo uses a transaction processing system (TPS) for the purpose of placing digital orders. For each of the following two capabilities of TPS, provide an example that illustrates why the capability is important for Aldo.

(i) Protection against errors resulting from overlapping updates

(ii) Protection from inconsistencies due to a failure of any component of a transaction

Analytics to Ilelp Online Retail With the ever-increasing adoption of Internet-connected devices, a customer's shopping journey can be all over the place. They may start by browsing products online and picking out a few items that they are interested in. They may then go to a store to try them on and to make a purchase. Alternatively, they may start in a store where they narrow down their selection to a few options, but then place their order online from their laptop/cellphone/tablet at home. Since customers have become flexible in their shopping patterns and have moved toward "omnichannel" shopping, they expect the same strategy from retailers. In other words, a customer who shops online today and may shop in-store tomorrow expects to see similar products with similar prices. Therefore, many retailers have realized that their inventory placement needs to become more flexible such that most possible inventory is kept in-store (as opposed to distribution centres) so both walk-in and the digital customers can access it. As a result, these retailers have embraced store fulfillment. To perform store fulfillment, traditional order management systems usually rely on transportation or distance-related objectives. But what if a product sold online is shipped from the closest store, which happens to have many in-store customers interested in the same product? What if the store runs out of the product and is out-of-stock when a walk-in customer asks for it? The Aldo Group (www.aldoshoes.com), a Canadian footwear and accessories manufacturer with 3,000 points of sale in more than 100 countries around the world, learned about this problem a while ago. Aldo realized that sometimes a number of stores were fulfilling online orders for products that were popular in-store too. To its surprise, the company learned after an analysis that some other stores were stocked with the same products, but their order management system was not sophisticated enough to suggest those locations for online order fulfillment. In addition, Aldo learned that at the end of the season, when it went through its recall process of the leftover inventory, there was so much wasted stock. As a result, Aldo decided to use business analytics for its order fulfillment process. Aldo adopted Celect (www.celect.com), a cloud-based business analytics platform that helps retailers optimize their overall inventory portfolios. So, now when a digital order comes in, Celect optimizes its fulfillment. Digital orders are all orders placed through e-commerce, a mobile app, or in-store order opportunities (where a customer wants a product that is out-of- stock at a store and thus, the store places an order for that product to be shipped from another store/warehouse). With business analytics, Aldo does not merely rely on minimizing distance or optimization. In fact, when an online order arrives, Celect, through its integration with Aldo's order management system, performs a multivariable analysis in real time and in a split second provides
