This is a simple front-end application intended to run on a mobile tablet, and communicate with a back-end database. This application will be used as a kiosk device to collect information on visitors for a corporation.

Description: The Visitor's View displays a simple form, greeting the user and requesting the user to sign-in. The following fields will be available for the user to enter data:

• Name
• Email
• Telephone #
• Company
• Official visit (checkbox)
• Escort required (checkbox)
• Excort name (if Escort is required)

Description: This view lists all the data entered by visitors as a table.

A three tier client-server architecture was selected for the creation of this project, consisting of client, server, and data tiers. The client tier presents the appropriate interface to the user so that visitor information can be entered or viewed. The data tier is a database running on a server responsible for storing and retrieving visitor information. The server tier (middle tier), is responsible for system logic and routing communication between the client, server, and data tiers. The client tier will ultimately be deployed on a tablet, and the data and server tiers will be deployed on an intranet server. Initial deployment during development will occur locally on a laptop.

The sign-in system requires a front-end framework for user interface implementation, a back-end framework for managing routing and logic, a back-end run-time environment, and finally, a database. Various technologies were considered for deployment of the system. In consideration of previous experience, and assessment of other web framework technologies, a MEVN stack was selected as the best option for deployment of the system. The MEVN stack consists of MongoDB, Express.js, Vue.js, and Node.js. Their roles within the system are listed below, along with the nonfunctional requirements of the system.

• Front-end framework for UI implementation (Vue.js)
• Back-end framework for routing and logic (Express.js)
• Back-end run-time environment (Node.js)
• Database (MongoDB)
• Development environment (Linux, Ubuntu Xenial 16.04)
• IDE (MS Visual Studio Code)
