Abstract: Systems and methods for data migration in multi-layer model-driven applications is provided. The traditional systems and methods simply provide for comparison based migration approaches, and thus face severe challenges in case of model-driven applications, wherein continuous capturing of transformations in model changes is required. Embodiment of the proposed disclosure provide for a changelog based data migration methodology by modelling, a model-driven application conceptual model; generating, a plurality of optimized data models from the modelling; extracting, from each of the plurality of optimized data models, at least one changelog capturing one or more model changes and transformations in each of the plurality of optimized data models; and executing the data migration using each of an executing changelog.

Abstract: The present disclosure is related to a system and method for controlling widgets of a table on a display using a server. The system is configured to receive inputs from user for controlling widgets of the table by specifying at least one configuration at the server end for at least one of a plurality of predefined configurations. It determines a plurality of events and invokes at least one event handler at the server end according to a predefined interface for the determined event. The event handler would then provide the component with response behavior. Further, the system specifies a plurality of observable properties wherein any change in the properties would be automatically tracked by the system and invoking the specified at least one event handler to control at least one widget of the table.
