Problems solved by technology

At present, the basic construction of computers and network equipment in all units of electric power construction has been basically sound; in terms of software, especially professional systems for engineering construction information management are relatively lacking, and it is difficult to meet the needs of power transmission and transformation project management
[0004] The current management system based on geographic information system has the same problem as other software systems: the demand will change with the change of management requirements, and the change of demand will bring about constant changes in development.
[0005] It can be seen from the above that the urgent problem to be solved is how to realize the expansion of the business domain while avoiding or reducing the work of system development, but there is no related description in the prior art

Abstract

The invention discloses a modeling method for a transmission and transformation project construction management display platform with extensible dimensionality. The modeling method comprises the following steps that geographical information dimensionality is subjected to abstraction, and then is made into a normalized ER (entity-relation) diagram; the normalized ER diagram is divided into dispersed business processing processes, and then each dispersed business processing process is independently modeled; subsequently, many-to-many relations containing data or additive non-keyword facts in the model ER diagram of a single business process are selected and marked to form a fact table; then all the rest tables are composited into a plane table with single-connection keywords capable of directly connecting to the fact table, so that a dimensionality table is formed. With the adoption of a dimensionality extension platform implemented by the modeling method, the secondary development problem is avoided directly through dimensionality definition and standard date access; according to the modeling method, modern information technology and advanced management idea are utilized to improve the efficiency and quality of project management, so that the informationization and real-time decision-making of transmission and transformation project management are realized.
