Methods and systems for management of data stored in discrete data containers

A method for managing data containers by a data access controller, wherein the method comprising:

• capturing modified data, by the data access controller, wherein the modified data refers to modifications made to de-containerized data associated with a data container and the modified data is captured based on at least one of a continuous manner, at a pre-configured interval and an occurrence of a pre-defined event;
• de-duplicating the modified data on determining duplicates in the modified data, by the data access controller;
• checking if at least one of rights and policies enables a user to access the modified data, by the data access controller, wherein the checking to access the modified data comprises determining, by the data access controller, at least one right to be applied for any or combination of attributes associated with the modified data based on a containerization parameter involving at least one of rights associated with the modified data, and a derivation of the rights, and wherein checking is further based on one or more of user attributes, data attributes, device attributes, and access type attributes;
• de-containerizing non-modified data present in the data container for providing the access to the user for the de-containerized non-modified data on determining that the at least one of the rights and the policies does not enable the user to access the modified data, by the data access controller;
• containerizing the modified data by reflecting the modified data in the data container, by the data access controller, wherein reflecting the modified data in the data container includes at least one of modifying the non-modified data present in the data container, discarding the non-modified data present in the data container and adding the modified data to the data container.
