How SAP In-Memory Helps its Customers Be Best-Run Businesses

How in-memory helped SAP innovate their business. Now this enables us to help our customers achieve things that otherwise would have been impossible. Through different use cases I want to show you what In-Memory brought to our customers and what the value is they derived from this.

With In-Memory Technology, a New Breed ISV Supports 30,000 Daily Visitors at Retailer Gekas from a Single Server

For six years, Swedish ISV Heads AB has been running their in-memory retail software suite at Gekås, a €500,000,000 “superstore” with 30,000 peak daily customers. For reference, this is three times the size of Walmart’s largest superstore. With only one 4-core server, Gekås manages the entire point of sale, accounting, ERP, inventory, warehouse and supply chain functions in real time. Number crunching reports that previously required hours or days and multiple staff to finish are now completed in seconds, literally at the push of a button.

Addressing 21st Century Data Challenges With 21st Century Technologies A Case From The Financial Markets

The Splendors and Miseries of the Distributed Streams

Java 8 introduced the Stream API - a modern, functional, and very powerful tool for performing bulk operations on collections of data. One of the main benefits of the Stream API is that it hides the details of iteration over the underlying data set, allowing for parallel processing within a single JVM, using a fork/join framework.

I will talk about the Stream API implementations for the development of parallel distributed across many machines and many JVMs programs on top Java 8 Stream API.

Using In-memory Computing for Fraud Detection

A real time fraud intelligence platform requires machine learning capabilities as well as customizability by industry, to be effective.  For example, in an online travel business, understanding where a flight ticket is purchased and where a user is going has an impact on determining fraud. But for a gaming company, the metrics for understanding fraud are somewhat different, as it's important to understand how a user buys an in-game credit and how soon thereafter that credit used.
