An entity-centric approach has been proposed to provide a consistent user experience in accessing a unified software applications suite effortlessly. Entities are connected with one another. The entities and the connectivity between them are reflected in all three functional layers of 3-tier client-server architecture. Every entity has a set of attributes and each attribute represents a data item or record of a particular type. The data items or records are represented in the form of card(s) as determined by contextualization and access control engines. The contextualization engine determines the origin of the user. The access control engine determines the access permission of every user.
