    This document describes the integration of a Relational Database with an Android-based graphical user interface for supporting the documentation of nurses’ tasks at the Point of Care in a hospital. To accomplish the integration a REST API is developed and a Relational Database is redesigned. The integration is engineered with an approach to secure communication and encrypted data storing/retrieval. The system uses mutual SSL authentication to transmit and encrypt the data between the Android Application and the Server. The data received via the REST API is encrypted into the database. The Database is re-designed to store the encrypted data in tables using the InnoDB engine of MariaDB. The data relationship is enforced using the physician, nurse and patient IDs as keys. An Android application back-end was developed to facilitate the communication between application’ graphical user interfaces and the REST API. The back end consists of classes that instantiate objects that the graphical user interfaces use to send data to be inserted in the database. The graphical user interfaces of the nursing documentation application are enhanced versions of a previous version of the nursing documentation system implemented on PDAs (Personal Digital Assistant). These were implemented in Java for the Android platform.
