Differences between a ERP and non-ERP products:
let us suppose that you want to implement a non erp product in a company .let us consider the block diagram.
>>one of the non erp product is oracle +vb script /java.
>>oracle is used to create database tables as well as maintain database tables.
>>vb script is used to design the application programs and to get the data from database and display.
>>in similar way if you implement a erp product .It contains the predefined database tables and programs .so we need not create database tables and maintain database table like in non erp product.
>>In this way we get added advantage with erp product.
>>ERP is a ready made product and according to the company we can mold the product.
SOME ERP PRODUCTS IN MARKET ARE:
- BAAN
- RAMCO
- PeopleSoft
- OracleApps
- SAP
1.Supermarkets:
BAAN used suitable for super markets.since 90% of database tables as well as programs are related to vender (selling persons) and customer (buying persons).
2.Finance companies for vehicles loans etc:
RAMCO is well suitable for this sort of organizations because the ramco contains predefined database tables and programs
in which 80% of database tables as well as programs are related to finance.
BAAN and RAMCO are suitabl for small scale industries.
3.People Soft:
The advantage of people soft is it contains very strong HR module compared to any other ERP products.
4.OracleApps:
The advantage of oracle apps is it contains very very strong finance module to any other erp products.
5.SAP:
All the departments in SAP are strong but HR department is little weak compared to people soft.And Finance department is little weak compared to oracle apps.
>>In the above diagram finance is implemented by oracle apps and hr is implemented by people soft.And remaning modules are implemented by SAP.
>>oracle apps or people soft cannot integrate with different erp products and run on same platform.
>>Where as SAP can integrate between different erp products and run on a common platform. this is the greatness of SAP .
ADVANTAGE OF SAP:
1. SAP is tightly integrated/closely integrated across all the modules/departments.
examples: if the sales department has sold some products ,automatically the update is given to Finance , and finance department collect the money from the customers.
2.SAP is developed in multi languages as well as mult curriences.
examples: suppose you have a company in india and purchased another company in china. the company in chain requires local software and the company in india is using SAP .then to communicate between two comapanies in india and china i.e communication between local china software and SAP software take more cost. To avoid this high cost SAP is developed in mutiple languages by this we can extend the sap in india to china without any local software.
example: if your company has purchased computers in america and delivered in india .The SAP automatically translate into te ither languages with updates in flucations in currencies.
this is used to communicate international vendors and customers.
3. SAP is ready made product which was developed by 5 IBM former employees in the year 1972 in Germany.
since SAP is ready made product custiomization is done with less effort or with minimum effort.
4. SAP is platform independent ie irrespective of operating system
we can run SAP on any systems.
5.SAP contains Cross Applications.
cross applications are used to exchange the data from one system to another system.
Development Of ABAP:
In 1972 when SAP was developed they thought that entire system must be developed in single language and that has given rise ABAP (Advanced Business Application Programing)
ABAP is not a case sensitive ,by using all remaning modules in are developed like sd,fi,etc.
