A system for at least one of replication, integration, consolidation and mobilization of data to integrate diverse data sources (105, 120), whereby the system includes: heterogeneous backend data sources; at least one input/output device (165, 175) being equipped with a client application and/or a mobile client application; a Replication Server for managing the replication of data (i) between at least two heterogeneous backend data sources (105, 120), and/or (ii) between at least one backend data source (105, 120) and the client application and/or the mobile client application in at least one input/output device (165, 175), and/or (iii) between the client applications and/or the mobile client applications in at least two input/output devices (165, 175) a Data Connector (110, 130) for connecting to any type of structured data sources (105, 120), a Communications Server for access to and from said input/output devices (165, 175) over a communication link (170, 180), and a common administration being formed by one single administration unit, whereby said server to manage the replication of data is connected via a communication link (145, 150) to said data connector (110, 130) and via another communication link to said communication server, and whereby said server to manage the replication of data includes a field level security module being configured to check user and device rights on field level before a replication is initiated, wherein said system is configured to utilize a field-driven data structure designed to address both replication and integration needs, wherein more than one instance is provided of one of said Replication Server, said Data connector and said Communication Server and each instance features its own data storage for facilitating independent operation. heterogeneous backend data sources; at least one input/output device (165, 175) being equipped with a client application and/or a mobile client application; a Replication Server for managing the replication of data (i) between at least two heterogeneous backend data sources (105, 120), and/or (ii) between at least one backend data source (105, 120) and the client application and/or the mobile client application in at least one input/output device (165, 175), and/or (iii) between the client applications and/or the mobile client applications in at least two input/output devices (165, 175) a Data Connector (110, 130) for connecting to any type of structured data sources (105, 120), a Communications Server for access to and from said input/output devices (165, 175) over a communication link (170, 180), and a common administration being formed by one single administration unit, whereby said server to manage the replication of data is connected via a communication link (145, 150) to said data connector (110, 130) and via another communication link to said communication server, and whereby said server to manage the replication of data includes a field level security module being configured to check user and device rights on field level before a replication is initiated, wherein said system is configured to utilize a field-driven data structure designed to address both replication and integration needs, wherein more than one instance is provided of one of said Replication Server, said Data connector and said Communication Server and each instance features its own data storage for facilitating independent operation. (i) between at least two heterogeneous backend data sources (105, 120), and/or (ii) between at least one backend data source (105, 120) and the client application and/or the mobile client application in at least one input/output device (165, 175), and/or (iii) between the client applications and/or the mobile client applications in at least two input/output devices (165, 175)
