Description
Technical Field

Background
The development of the building industry informatization is usually accompanied by the upgrading of the traditional construction mode and the diversification of enterprise business, meanwhile, business datamation is actively promoted by each enterprise, so that more and more enterprises form vertical data centers along with the development of each vertical business, and the BDM is used for communicating the vertical data and constructing the vertical data according to a uniform standard so as to achieve the aims of cooperative work, cost reduction, application efficiency improvement and business enabling inside and among enterprises in the building industry.
The BDM carries out horizontal association and unification on data accumulated in different fields of the construction industry for many years according to service characteristics, carries out longitudinal layering according to data purposes and finally precipitates the data into public data service capacity. The horizontal association and unification are used for realizing that the same things (facilities, equipment, personnel, contract and the like) have the same and unique identification in different information systems and the attribute description is consistent; the longitudinal layering is to decompose original production data into multiple dimensions after processing, and serve the requirements of data analysis, data calling and the like of each participant in the whole life cycle of a project.
A Building Datamation Model (BDM), a datamation representation of Building information, BDM ═ Σ CDM > BIM.
Building Component (Building Component) Building components are components that form a Building. If a building is considered a product, a building element is a component of the product.

CDM is a data standard, applicable to component data models. The CDM standard aims to provide a construction process intermediate data standard which is independent of any specific system and used for describing connection design and operation and maintenance for the construction industry, and is suitable for information creation and application of the construction process and storage and application of project life-cycle building information. The CDM standard is a database containing a set of generic attributes (called parameters). The CDM standard component of the same type (class), some or all of which may have different values but the set of parameters (name and meaning) is the same, is referred to as a CDM standard type or type, each type having the same set of parameters, referred to as a CDM type parameter
The special CDM standard is a CDM standard established for different members of the same type based on a general CDM standard, facilitating use of various special members. For example, different types of cast-in-place piles may be assigned different types of cast-in-place pile-specific CDM standards by increasing or decreasing parameters according to the cast-in-place (round) pile-generic CDM standard.
The universal CDM standard is a component data standard that is uniformly specified in a Building Data Model (BDM), and includes piles, platforms, beams, plates, columns, walls, stairs, doors, windows, equipment, pipes, and the like.
