Application server exists at a remote a location as compared to the location of the user PC. In simple words, it’s a client server architecture. Database and Application may exist on the same or different physical location. A two-tier architecture is a software architecture in which a presentation layer or interface runs on a client, and a data layer or data structure gets stored on a server. This is the top layer of the system. Architecture Overview As illustrated in the following diagram, the basic system architecture has a classic 3-tier approach: 3-Tier Architecture of SAP HANA with XS Advanced There is a distinction between the overall SAP HANA system and the SAP HANA XS advanced application server. 1) Presentation Layer: Presentation Layer provides means of: Input, allowing the users to manipulate the system Output, allowing the system to produce the results of user s manipulation SAP is having Graphical User interface (SAP GUI). SAP has manufactured its own database named Hana but is compatible with all major databases such as Oracle.All R/3 data is stored in the database. Step 4) Once user is assigned the dialog workprocess then user authorizations, user's current setting are rolled in to work-process in shared memory to access user's data.Once dialog step is executed then user's data is rolled out from workprocess. SAP-R/3 Workflow in SAP-3 Tier Architecture. Three-tier architecture is a software design pattern and a well-established software architecture. AWS CloudFormation provides an easy way to create and manage a collection of related AWS resources, provisioning and updating them in an orderly and predictable fashion. An MVC architecture is best defined using a Sequence Diagram. Separating these two components into different locations represents a two-tier architecture, as opposed to a single-tier architecture. The Business Objects Enterprise technical architecture is composed of a set of components or so called servers, optimized for specific tasks and operations. Real-time integration ensures that any change or upgrade in one application causes the data to be modified or updated automatically in the other applications involved. With SAP R/3, SAP ushers in a new generation of enterprise software — from mainframe computing (client-server architecture) to the three-tier architecture of database, application, and user interface. SAP R/3 uses three-tier architecture. Remark :-For graphical display of R/3 workflow,go through with the attachment. 3-tier means exactly how, by placing certain resources on 3-levels, as seen in the diagram below. Here the communication is one to one. R/3 repository, objects are used in ABAP workbench. It's called front-end. Since ERP is a multiple modular application, it offers a lot of useful tools that business people can use to enhance the internal processes in their organizations. Releasing a purchasing document means approving it. Dialog step means the screen movements. Hit ratio should be always higher than miss ratio. Step 5) First work process will find the data in the buffer. According to me..what i understand about the SAP-R/3 workflow is :-. Dispatcher :- is a logical unit  which receives user input and sent result to the user                                        accordingly and it cannot hold the data itself. In a transaction, when a users jumps from one screen to other the process is called a dialog step. The above figure shows the architecture of two-tier. Introduction: Architecture Tiers. The Dispatcher only assigns requests to Work Processes. Dispatcher follows First in First out rule. This Quick Start uses AWS CloudFormation, the AWS Command Line Interface (AWS CLI) for Linux, and custom scripts to deploy SAP HANA on AWS. Hi Venu, SAP R/3 is a client server model, using 3-tiered architecture. R signifies. The below diagram represents a software-oriented view of the R/3 System. One more component is JCO. JCO is used to handle communication between java dispatcher and ABAP dispatcher when system is configured as ABAP+Java. The Application Layer consists of one or more application servers and a message server. Note :- If Work Processes are busy,Dispatcher sent requests to the Shared                                          Memory temporarily(because Dispatcher cannot hold the data itself). For larger SAP systems we would scale out the app servers across multiple virtual machines – this is a 3-tier setup. Manufacturing is all about the flow of engineering, quality control, expenditure and cost control, etc. The architecture in this example is for an SAP S/4HANA 3-tier (PRD/QAS/DEV) environment with Multi-AZ high availability for production. If user runs a report in background then background work process is assigned to the user.When some modifications are done at database level then update workprocess is assigned.So as per user's action workprocess is assigned. For example, when user login to the system then Dialog work process is assigned to the user. Two Tier Clients- Server Architectures Two tire client server architecture consists of two logical layer : client layer and server layer. The Presentation Layer contains the software components that make up the SAPgui (graphical user interface). Each application server contains a set of services used to run the R/3 System. If not then it again sent to the Work process for re-processing(same as described above..). User's PC:-  Users can access SAP system in two ways:-. Sap Architecture … It uses this information to assign an appropriate server when a user logs onto the system. 3-tier Architecture (Client-Server) The client server model is one used by many organisations all over the world, and is a way to distribute software resources to many locations. Front-end takes the user's requests to database server and application servers. Architecture. Step 2) Request is stored in Request queues first. Only the front-end is installed in the user's PC not the application/database servers. Presentation layer is the first layer of R/3.
