Problems solved by technology

In order to realize the construction of the project cost database and realize the classification and statistics of project cost data, a large amount of manual labor is required to manually classify and adjust the data and then manually import the data into the database. Since the project cost data often contains a large amount of detailed data, the The manual collection and statistics of each project cost file is a huge project, so this has become the bottleneck of the construction of the project cost database system

Embodiment Construction

[0012] A binary storage format of engineering cost data that supports aggregation statistics according to the present invention includes the following parts:

[0013] The first part: defines the classified storage structure of the project cost database, which uses binary files to store the content of the cost data and supports distributed storage of data files;

[0014] The second part: Provides standard functions that are convenient for querying and collecting statistics to realize data access. All access functions are independent of the database system, and are implemented by directly facing the cost data binary file;

[0015] The third part: support the standard JDBC data interface to access cost data. The data engine is based on the defined binary file of the project cost database. The data engine can provide services for distributed binary data files and provide services for external systems in the form of JDBC.

[0016] Specific as figure 1 Shown:

[0017] Part I: Cost...

Abstract

The invention relates to a project cost data binary storage format supporting collection statistics. The project cost data binary storage format comprises a cost data structure definition, a cost data access collection function library and a JDBC standard Java database access interface. According to the method, the project cost database system can dynamically determine the bottom storage format, and the functions of flexible collection, structure adjustment and storage optimization of the cost database system are achieved. The data stored in the project cost data storage format can directly generate a project economic index table, a project cost content index and a complete cost standard list, the project cost database system construction model is optimized, the project cost data operation efficiency is improved, and a bottom-layer technical guarantee is provided for project cost data recycling.

Description

technical field [0001] The invention relates to an engineering cost data storage format, in particular, a high-performance binary engineering cost data storage format that needs to realize a large number of statistical calculations. Background technique [0002] The collection and statistics of engineering cost data is an urgent and extremely difficult requirement in the construction of the current engineering cost database system. The main reason is the particularity of the engineering cost industry, which makes the engineering cost data compiled by most engineering cost compilation software stored in data files similar to XML. In order to realize the construction of the project cost database and realize the classification and statistics of project cost data, a large amount of manual labor is required to manually classify and adjust the data and then manually import the data into the database. Since the project cost data often contains a large amount of detailed data, the ...
