Technologies required for ERP
Client/Server technologyThe Client/Server technology model is the model on which today's softwares are developed. A Client/Server model is one in which the client computer is identified separately from the server computer.
In this model, the client computer makes the request and the server computer accepts this request, processes the request and initiates a response. Under this model, the client hosts certain parts of the software while server hosts certain parts of the software.
This design architecture allows hosting of resources like databases in central locations and distributing resources like user interface and reporting services to other locations.
Typically, in a client/server environment, the desktop computers are connected using networking devices like hubs and routers to centrally located servers like database servers, application servers, print servers and file servers.
When developing an ERP software for an organization, whether located in a single location or spread over multiple locations it is advisable and strongly recommended to design the ERP software based on this model.
Database systemsERP systems use relational database management systems (RDBMS) to store enterprise data. Many of you will be aware that a database system is a computer software which is used to collect and store data.
In an ERP system too, a database system is used to collect and store transaction data of an organization. The database software manages this data efficiently and provides features to maintain the integrity of the data.
Modern database systems provide many features such as structured query language to directly access the data from the database, transaction mechanism to enable concurrent access of database, stored procedures to enforce business logic, triggers to initiate actions, security to limit access of parts and/or features of the database.
ERP software developers should be proficient in using various interface tools of the database software.
Development toolsDevelopment tools such as Visual Basic.net or C#.net are required for ERP software development. These tools enable a programmer to create a major part of the ERP software application except the database.
These tools have highly advanced features to quickly create data entry forms, client side validations, programs to implement business logic, programs to interact with the database and programs to communicate between different parts of the application.
These software tools come with features to debug while creating the above programs, easily manage, maintain and package the ERP software for deployment.
