Abstract: A system and method for dynamically updating a travel itinerary are described herein. The system 101 receives, user inputs for selecting items. The system 101 creates electronic carts based on the user inputs. Each electronic cart is associated with an unique identifier. Each electronic cart comprises items. The system 101 invokes, a rendering module for positioning the electronic carts on a GUI based on user defined time and date. The system 101 generates one or more events. Each event comprises items associated with electronic carts. The system 101 displays events on the GUI using the rendering module. The system 101 enables a user to perform a task selected from a group of tasks based on the unique identifiers associated with electronic carts. Further, the system 101 dynamically updates one or more items associated with the at least one electronic cart based on impact of the task.

Abstract: A method and a system for facilitating multitenancy of services are described herein. The processor 201 of the system may execute instructions stored in memory 203 for generating, fine grained services, wherein fine-grained services comprise code, content and configurations. The processor 201 may orchestrate, fine-grained services in order to form coarse grained services. The processor 201 may receive a request from a user. The processor 201 may identify, the tenant associated with received request from the plurality of tenants. The processor 201 may load, tenant specific content and configuration. The processor 201 may invoke tenant specific flow. The processor 201 may perform dynamic variation on the current code, content and configurations of fine-grained services and coarse-grained services by injecting tenant specific code, content and\or configuration.
