Abstract

Purpose

Currently, the results of database acquisition are variously expressed, but it seems that users’ understanding degree will be improved by expressing some search results such as images of products of shopping sites in three dimensions rather than two dimensions. Therefore, this paper aims to propose a system for automatically generating 3D virtual museum that arranges 3D objects with various layouts from the acquisition result of relation database by SuperSQL query.

Design/methodology/approach

The study extended the SuperSQL to generate 3D virtual reality museum using declarative queries on relational data stored in a database.

Findings

This system made it possible to generate various three-dimensional virtual spaces with different layouts through simple queries.

Originality/value

It can be said that this system is useful in that a complicated three-dimensional virtual space can be generated by describing a simple query and a different three-dimensional virtual space can be generated by slightly changing the query or database content. When creating a virtual museum, if there are too many exhibitions or when changing the layout, the burden on the user will be high. But in this system, it is possible to automatically generate various virtual museums easily and reduce the burden on users.

Abstract

Purpose

With the rapid spread of smartphones and tablets, it is becoming necessary for web developers to create responsive web pages which are visually appealing on devices of various sizes. However, building responsive UIs is a very challenging task, requiring deep knowledge of HTML and CSS. This paper aims to propose an approach to generate responsive web pages using SuperSQL, which is an extension of SQL that can format data retrieved from a database into various kinds of structured documents.

Design/methodology/approach

By incorporating the methodology of bootstrap, a grid-based framework for front-end development, the authors have made it possible to create responsive web pages from simple SuperSQL queries. In addition, by utilizing SuperSQL’s unique feature that can describe the structure of the output web page, the authors have proposed and implemented a mechanism to automatically optimize the web content’s size and position.

Findings

In the evaluation, the authors created some actual web applications with and without the use of SuperSQL and compared the code amount (number of lines). As a result, when using the proposed system, the amount of code was reduced to about 1/5. The authors also compared the layout generated by the proposed automatic layout generation mechanism with the responsive layout that was generated manually. As a result, the automatic layout generation mechanism created the same layout as the manually created layout 74.8 per cent of the time, and the user satisfaction level turned out to be 85.8 per cent.

Originality/value

The way to generate a responsive HTML by using a single SuperSQL query, and the mechanism for automatic responsive layout generation.
