Say, business is increase in the next 6 years and hence demand increase. There fore business is done manually and demand increases, burden and the employees increases, efficiency decreases, loses existing. But due to some reasons e.g. competition if we lose this demand, man power becomes waste. There fore alternative solution is to eliminate the manual process, atomization or computerization is adopted, which is increase in efficiency and burden. Here we required software and hard ware So, the company XYZ has installed computers. So, all the departments have to use computers for their business transactions and functions. Now, they required software to run the business. To perform financial activities some software applications software package like WINGS, TALLY, FOCUS e.t.c.. are available. For S&D software applications M.S. office is used. Or Any customized product (VB as front end and oracle as back end— software components like WIPRO, IBM customized these products) E.g. railway reservation e.t.c.. For purchasing software applications M.S. office or customer product. For engineering CADD/CAM is used. For H.R some customer product. So, the employee XYZ is running their business by these individual packages. Which has no integration? There fore output of the particular application as not shared by other applications electronically. E.g. when sales order is raised, then if requirement should be transferred to finance, procurement, shipping departments. Integration should be there. So, the sales people has to create 5 copies and sent these to all the departments and customer manually which is risky. e.g. If there is a problem that this requirement does not reach the shipping department in time, customer will not get the product in time Business losses customer. Integration is required.

SAP R/3:R/3—real time 3- tier architecture. Single- tier- architecture—stand alone system e.g. P.C. (All 3 layers are existed in the same system.)

Back end where data Base is existed

Data base layer

Core component (Code, program)

Application layer

Front end GUI

Presentation layer

2- TIER ARCHTECTURE: - (multi user concept) Draw back: - system performance is affected. E.g. IBM, siemens, mainframes. DBL SERVER (which is logically connected to clients)
