SAP
Enterprise ERPSAP is the world's largest enterprise resource planning software company, and for many Fortune 500 businesses, it is the backbone that ties together finance, supply chain, manufacturing, human resources, and procurement into a single system of record. When building custom web applications for companies that run SAP, integration is almost always part of the conversation. Whether it's pulling real-time inventory data from SAP S/4HANA into a customer-facing portal, syncing order data between a custom app and SAP's materials management module, or building dashboards that surface SAP financial data in a way that's actually usable, the work usually involves SAP's RFC, BAPI, or OData APIs. SAP's ecosystem is massive and notoriously complex, but that complexity is exactly why custom middleware and purpose-built interfaces are so valuable, they give teams access to the data they need without forcing everyone to learn SAP's labyrinthine UI.
How It Changed Everything
SAP was founded in 1972 in Mannheim, Germany by five former IBM engineers: Dietmar Hopp, Hasso Plattner, Claus Wellenreuther, Klaus Tschira, and Hans-Werner Hector. They had been working on an enterprise system for IBM called System/360, but when IBM scrapped the project, the five engineers saw an opportunity. They left IBM, pooled their resources, and started Systemanalyse Programmentwicklung, "System Analysis Program Development", working out of modest offices and coding through the night. Their first product, SAP R/1, processed financial transactions in real time instead of overnight batches, which was revolutionary at the time. By the 1990s, SAP R/3 had become the global standard for enterprise software, and today SAP serves over 400,000 customers in 180 countries, processing 77% of the world's transaction revenue.
One Thing Most People Miss
SAP's co-founder Hasso Plattner personally funded and drove the development of SAP HANA, the in-memory database that transformed the company's entire product line. What most people don't know is that Plattner essentially bet the company's future on HANA against internal resistance, many SAP executives thought the existing Oracle-based architecture was fine. Plattner built the early HANA prototypes at the Hasso Plattner Institute in Potsdam, Germany, which he founded and funded out of his own pocket. Also, the name "SAP" was partly chosen because it allowed the founders to keep their IBM employee cafeteria cards, which were sorted alphabetically, SAP came right after their IBM division's abbreviation.
