FIELD OF THE INVENTION
The present invention relates to a system and method for deployment variability in Point of Sale (POS) operations. More specifically, the present invention relates to system and method of deployment variability' in the Point of Sale wherein the deployment can be a standalone model or in an n-tiered mode, based on the business needs, without replicating the Point of Sale data across multiple levels of organizations
BACKGROUND OF THE INVENTION
In retail business environment, superior customer service always has the power to transform an occasional buyer into a loyal customer. Towards leveraging this potential, retail outlets seek to upgrade legacy points of service and enhance customer service with efficient-in store operations. Further, there is a genuine requirement for retailers to shift product centric assortment planning to consumer assortment planning so that retailers could create tailored assortments. In addition to this, retail outlets now are focusing on localization of assortments _ to cater to the unique needs of customer segments and thus are required to synchronize assortment planning with merchandise planning, space planning and allocation. To fulfill this requirement, several POS deployments have come up in the market.
Typical POS products comprise a POS Till, a POS Back Office and a POS Central Instance with specific deployment environment wherein the deployment is based on the number of stores and their mode of operations. The POS is deployed in such a manner that the POS Till runs on a standalone infrastructure, the POS Back Office runs on servers installed at store level, and the POS Central Instance runs on servers deployed at a corporate level. However, with this type of set-up, there is always a possibility of the POS data being replicated thereby creating a bottleneck for the product vendor and also for the retailer.
The requirements of the reatilers may also vary, some retailers POS system require the POS Till to be available all the time with or without other relevant modules. While, some retailers require the POS Till to post the data to the corporate data center quickly so that the customer is quickly serviced in any chain store to provide quick loyalty benefits. To meet both the needs at a single point is challenging and makes POS configuration complicated.

It would be advantageous therefore to provide a cost-effective Deployment variability in POS configurations that could cater to the needs of small to big retail outlets wherein the deployment variability model includes need of servers on need basis having different configurations for deployment to avoid replication of POS data irrespective of the deployment environment. Therefore making it possible to deploy POS system in a variety of ways to meet the need of retailers.
SUMMARY OF THE INVENTION
Embodiments of the present invention overcome shortcomings of prior POS deployment models by eliminating the risk of replicating the data.
An object of the present invention is to provide a method and system for deployment variability having different deployment variables for different scenarios, wherein, in one instance the business logic of a POS Till, a POS Back Office, and a POS Central Instance remain in a standalone mode and in other instance the business logic of the POS Till, the POS Back Office, and the POS Central Instance could be incorporated in a store, regional or corporate central server, based on the requirement.
Another object of the invention is to provide deployment variability in a POS, wherein the deployment variability in the POS is deployed in a plurality of scenarios based on requirement.
