Dec 1, 2017 · This research focuses on defining a schema and transformation rules to bring BIM data into a form that is easily queried. The schema is defined using popular relational database structure following an established star schema model that is well-defined within the data warehouse domain.

Oct 20, 2024 · A schema is the overall logical structure of a database that defines how the data is organized and how relationships among data are maintained. It can be viewed as a blueprint or architecture of the database that defines tables, fields, data types, and relationships.

The first is a new approach to transform BIM data into a simple database schema and to make it easily query-able by adopting the data warehouse approach. Geometry and spatial operations are also commonly needed for automating rules, and therefore the second approach is to integrate these into a database in the form of multiple representations.

Jun 1, 2023 · Previous research has explored linking textual data with BIM through the use of relational schemas, concept mapping, and ontologies. However, these methods are structured and static, failing to match the non-parametric and evolutionary nature of unstructured data.

Nov 6, 2020 · It presents the authors’ concept of using a single database for BIM and GIS systems while preserving the IFC (Industry Foundation Classes) and CityGML source data models typical for them. The research joins some other works in this field, complementing them and adding a new perspective.

The primary objective of this query-able BIM approach is to provide a successful data 16 retrieval, manipulation, and management environment that offers easy and efficient queries, an

Oct 1, 2024 · This paper applies Design Science Research methodology to explore how the IFC should be specified so that BIM actors can meet the representation context of a project translating data through Inheritance Diagrams, which offer auxiliary contributions.

This modularized BIM-based design validation framework is expected to help automatically and iteratively evaluate the level of quality and defects of information conveyed in a given building model as an essential part of the early design process.

Jul 13, 2022 · Data are individual facts, statistics, or items of information, often numeric. In a more technical sense, data are a set of values of qualitative or quantitative variables about one or more persons or objects. Data gives us information about objects or persons and it …

Dec 3, 2021 · Building information modelling (BIM) is recognized as a synonym of digital innovation for the built environment. In the past decades, professionals have been moving from the use of computer-aided design (CAD) to BIM to manage projects in a more effective way.
