SAPis pushing MAXDB (without any license key), Microsoft SQL Server & IBM DB2 with discounted prizes.ESS is an online Portal that will enable COSA employees to access their important information through an easy-to-use web site. It has its own queue, process, buffers, and request handling mechanism. It is the area where the complete data resides. It absorbs the load both from Client and the server. ![]() It has dispatcher to process and monitor the user request, work process to process and interpret the requests, Buffer areas to store the frequently accessed data. It is used to handle the user request and process them to the database. SAP GUI for JAVA (On all OS where JAVA is supported).It is a client for all the SAP Solutions. SAP uses the industry specific 3-Layer Architecture and named it as R/3 Architecture. It is intelligent to store the frequently accessed data thereby reducing the load on the server. It also contains the task interpreters to interpret the user request and route it to the server. It has its own queue mechanism to process the user request. all the clients are freed with DB Clients.Īpplication server/ layer handle the request and process them based on FIFO (First in and First out). It is installed with a database client to communicate with the database server i.e. It is the Intermediate layer in between the Client and the Server. The advantages of deploying Application Layer: Need for the Middle Layer: R/3 Architecture The server side processing is only takes place for new requests there by server resources are optimally used.Intermediate buffers are available for the frequently accessed content to reduce the load on the Database server.Work process task handlers are used to interpret and process the request.User requests are served based on the FIFO using dispatcher.There is a queue mechanism to handle the request there by reducing the load on the client and server.there will be only one DB Client for Application server earlier each client needs DB Client software) DB Client is installed to free up the clients (i.e.The result is the Application layer/ Server Application server is deployed and it provides the following functionality The need of middle layer/ tier rose to come out of the steps. The server side processing consumes resources to process (Interpret the user requests).There is no queue mechanism to handle the requests there by servers are heavily loaded.No intermediate buffers for the frequently accessed content. ![]() The major disadvantage of Client Server architecture is Client Server Environment:Ĭlient requests and server responds. These are the disadvantages of R/2 Systems. Server needs to process the request (Understanding the user language).There is no queuing mechanism and only server queues are maintained.Servers are heavily loaded/ traffic, long queues there by reducing the performance of the servers.Each request is processed by communicating with server only I.e.Client uses DB Client software to communicate with server. ![]()
