Apps commonly store data related to user activity like identity, login credentials, personalization information, recent actions, shopping cart, and more. Session data can vary by application type or industry, for example an e-commerce retailer may hold a customerâs login and authentication details, shopping cart items, browsing history, preferences, and recommendations. A session for a brokerage application may store an investorâs portfolio details, preferred portfolio views, current trades, and open orders. A video game session may keep the playerâs current level, score, and control configuration and maintain the gameâs state.
