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. Interactions capture entity communications across the unified software suite. The entities can communicate or interact across various channels like mail, call, messages, webinar, etc. Interaction across each channel is possible by one or more software applications. The interactions trends can be represented by channel and by entity. When interactions are filtered by channel, a channel-wise list for each type of interaction, e.g., mail, chat, call, etc. is provided. When interactions are filtered by entity, a list of entities involved in the interaction is represented along with the interaction.
