By centralizing data management, SAP software provides multiple business functions with a single view of the truth.

This helps companies better manage complex business processes by giving employees of different departments easy access to real-time insights across the enterprise. As a result, businesses can accelerate workflows, improve operational efficiency, raise productivity, enhance customer experiences — and ultimately increase profits.

SAP was one of the first companies to develop standard software for business solutions and continues to offer industry-leading ERP solutions. SAP began with a small group of friends who had a big idea: a vision of a digitally connected enterprise. Dietmar Hopp, Klaus Tschira, Hans-Werner Hector, Hasso Plattner, and Claus Wellenreuther started the company as a private partnership in and launched the first commercial product a year later.

SAP helps companies and organizations of all sizes and industries run their businesses profitably, adapt continuously, and grow sustainably. The company develops software solutions that are used by small businesses, midsize companies, and large corporations. With standard applications, industry solutions, platforms, and technologies, every business process can be mapped and designed.

The software collects and processes data on one platform, from raw material purchasing to production and customer satisfaction. SAP solutions can also be used to create forecasts, such as when a machine needs to be repaired or how revenue will develop in the next half year. In addition, SAP helps customers seamlessly link operational data on business processes with experience data on emotional factors such as purchase experience and customer feedback.

This enables companies to better understand and respond to their customers. SAP offers solutions across a wide range of areas:. Experience best-selling SAP software in action. Read in-depth feature articles on current business and technology trends, customer stories and videos on SAP TV.

The three-tier architecture is the recommended one because it enables high scalability and flexibility but SAP can also be deployed on two- and one-tier architectures. Figure 1 provides a graphical illustration of the differences between these architectures. In the three-tier SAP architecture, the presentation tier provides the interface to the user, the application tier processes the business logic, and the database tier stores the business data.

It executes the business logic, responsible for processing client transactions, print jobs, running reports, coordinating access to the database, and interfacing with other applications.

It is possible to distribute the application logic between several server machines in situations when the load exceeds processing power of a single server. The Database Tier The database is used for storing two types of objects: the business-generated data and the SAP application programs. The business-generated data represents data objects created by users as part of various business processes. For instance, sales orders or customer master records are classified as the business-generated data.

Advertisement It is possible to use databases from different vendors for instance, Oracle or Microsoft and it is up to the company to decide which database vendor to choose. Usually, the database license is included into the price of SAP.

The database tier has the highest requirements for availability, reliability, and performance because usually each SAP system is deployed on one database instance. There are situations when three tiers can be reduced to two or one.

The possibility of these situations depends on available processing power and number of business users. For example, it is possible to install all three SAP tiers on a single computer for demo purposes. On the other hand, large SAP productive installations require multiple powerful servers for each of the tiers in order to ensure good performance of the SAP system. Above these tiers, SAP architecture can be further segmented into several application modules.

Each module contains the SAP application programs and business data related to a specific business area such as financial accounting FI or materials management MM. Although SAP application modules cover completely different business process and business areas, technically they work in a similar manner.

For this reason, our article is not going to focus on any particular SAP module but will instead explain how does SAP work with the three-tier architecture in general. As it was explained above, the heart or kernel of the SAP system is in the application tier application server. Furthermore, it stores data in the database tier. All kernel processes that are started or stopped are called an SAP instance. SAP ERP system typically contains several instances in such a way that each instance is running on a dedicated server computer.

Each SAP instance contains a dispatcher and several work processes. The dispatcher distributes tasks to one of the work processes. The SAP system has different kinds of work processes that were created for various tasks. Here is the list of their types:. Figure 3 illustrates a generic SAP application instance with one dispatcher and several work processes.

The central instance has two additional components called the message process M and the enqueue server E. The message process M of the central instance is used for establishing communication between various application instances included in the SAP system. For instance, when a user logins to the SAP system, it is automatically assigned by the message process to one of the available application instances.

Next, all the transactional requests related to this user will be re-routed by the message process to the chosen application instance. The enqueue server E of the central instance is used for managing locks on the database tables. These locks ensure that database updates are performed in a proper sequence and guarantee consistency of the business data. The central instance is schematically illustrated on Figure 4. SAP system works in the following way: A request arrives from the presentation tier it can be an online request from a user or a request related to a batch job or anything else.

This request is analyzed by the dispatcher of the SAP central instance. The dispatcher passes the request to the message process M. The message process M decided whether this request should be processed on this instance or needs to be forwarded to a different instance for example, an instance with a lower computing load.
