A low code report realization method based on SIS production operation data specifically comprises the following operations:
step 1, classifying according to business data by developers based on SIS production operation data, analyzing, counting, deciding, mining and establishing theme data aiming at the data, and constructing a data warehouse of SIS production operation.
The step is to construct a report data source, namely a multidimensional fact data summary table, and the specific operations are as follows:
(1) as shown in fig. 1, theme data (measuring points, indexes, fuels, etc.) are subjected to data denoising from a service table by an ETL tool from various service systems (such as SIS real-time data systems, production operation data systems, fuel overall process data systems and other service data systems), cleaned, and subjected to data conversion of service data associated tables, and then introduced into a data warehouse HDFS file system in a paradigm modeling and periodic increment manner, and the associated data between different service systems are uniformly and normatively stored as fact data detail.
(2) And periodically extracting all public dimension data (organization, personnel, equipment and time) from each business system through an ETL tool, for example, in a second step shown in FIG. 1, forming a dimension layer data table which is used for uniformly managing the dimension tables and is a designed dimension set. The core design of the dimension table is to determine that dimension attributes (filtering conditions, grouping conditions, sequencing and the like during later-stage OLAP query) are as rich as possible and are designed in a flat mode; and determining which tables and main dimension tables have association relations, and selecting some attributes of the tables for the dimension attributes of the main dimension tables.
(3) As shown in fig. 1, the service data (index multidimensional data summary table, overhaul multidimensional data summary table, fuel multidimensional data summary table, work order multidimensional data summary table, and the like) oriented to a topic domain is summarized by performing clear conversion, data cleaning, field merging, null value processing, dirty data processing according to dimensionality elements and performing minimum granularity summary aggregation or measurement aggregation on each dimensionality element based on basic data, namely a fact data detail table, on a data detail layer and stored in a data summarization layer in a data warehouse; and continuously iterating and optimizing the service data according to the requirements of the service layer, and finishing more and more service requirements of the report data through the data of the data summarizing layer along with the passage of time.
And 2, taking the data warehouse of enterprise-level SIS production operation as a data source, selecting single subject data in the data warehouse as the content of multi-dimensional analysis of the report, and determining the report subject.

(2) If the fact summary table is selected not to exist in the data warehouse of SIS production operation, for example, in a flow chart, a program calls a statistical calculation engine in the data warehouse to carry out measurement aggregation according to dimensionality, and carries out a statistical calculation off-line (historical) data multidimensional summary recovery task to establish the multidimensional fact summary table.
And 3, searching out the associated public dimension set in the data warehouse according to the selected report topic, and selecting one or more dimensions from the dimension set as report parameters.
As shown in fig. 2, the specific operation of step 3 is: the report back-end service autonomously loads the public dimension set and the measurement set associated with the report back-end service according to the report theme, report parameters can be set from the dimension set and the measurement set, one or more dimension element sets are selected as the report parameters, as shown in fig. 3, the report parameters (such as a unit #1#2#3, a time, a year, a month, a day, and the like) and the display types of a drop-down box, a unit box, a check box, a date type are designated as the header of the report, the report parameters are the contents of the report operation area, and the numerical values of the adjustable parameters achieve the purpose of updating the data contents of the report.
And 4, selecting a field element set of the multidimensional fact data summary table in the data warehouse as a report data set according to the report theme.
As shown in fig. 2, the key point of this step is to extract the dimension set, the data set and the measurement set in the fact summary table to form a report data set; selecting multi-column data from a multi-dimensional fact summary table (wide table) selected from a data warehouse as report data; the back-end service automatically loads all default column names in a multidimensional fact summary table (wide table) as a report data set according to the report theme, and can also select the column names as report data set elements.
Step 5, dragging the report data set collection element to realize data binding with the cell through a web client designer as shown in FIG. 2; configuring report style, layout and color matching; and inserting visualization operations including charts, pictures, tables and the like to realize the configuration of the report template.
The step visually configures the report template through the combination of the designer and the report dataset, and the specific operation comprises two parts:
(1) and static content: report styles, layouts, color matching, charts, pictures, tables, fonts and the like are directly edited and stored by an online visualization designer.
(2) And dynamic content: the designer loads a report data set, performs data binding with a grid in a form by dragging elements of the report data set, generates placeholders, specifies the expansion direction of the placeholders to be transverse expansion or longitudinal expansion, forms special placeholders, and stores the placeholders in a report template.
As shown in fig. 2, the visual configuration and display of the report data set are easily realized by the 2 steps of visual chart, zero coding and dragging operation.
Step 6, analyzing the report template content, dynamically constructing and loading json text, generating an online report, changing the dimension level through report parameters, and transforming the analysis granularity of chart data to realize the report scrolling and drilling operation functions; meanwhile, when other dimension element values in the parameters are modified, the report slicing or blocking function is realized; the interactive query of the multi-dimensional data report and the display analysis from multiple visual angles are easily realized.
In the step, the report back-end service analyzes the report template content to obtain the elements and the display position of the binding data set; and then dynamically inquiring a data binding placeholder on a data replacement display position by combining report parameters, performing iterative supplement of a dynamic data set in the position according to the placeholder expansion direction, finally generating a json text by a back-end service, transmitting the json text to a front-end UI, automatically loading report parameters on a header operation area for performing multi-dimensional data analysis by the front-end UI of the report system, loading the json text content, and displaying the report content in a web visual designer, thereby completing the functions of customized report development and display.
By using the invention, not only can the customization of the report be easily realized, but also the OLAP multidimensional analysis can be carried out on the report, the heavy participation of system developers is liberated, and the first user can formulate a professional data chart.
