Create a table
- In the left-side navigation pane, choose AnalyticDB for MySQL URL, select a table type, and add datasets to the data-based decision system for
subsequent data analysis and dashboard display. . Select the previously configured
- Database table: You can directly add tables in the AnalyticDB for MySQL database.
- SQL datasets: You can execute SQL statements to generate datasets that are required for analysis.
- Self-service datasets: You can add self-service datasets to database tables or SQL datasets.
- Select base table fields. Then you can perform operations such as filtering, grouping,
summarizing, adding columns, and merging.
In market basket analysis, user consumption data is analyzed and different commodities are associated to mine their connections. The following example demonstrates how to create a table and import data, and use FineBI to connnect to an AnalyticDB for MySQL database and create a basket analysis dashboard.
- Download the Summary table of commodity sales table sample data.
- Create a table in the AnalyticDB for MySQL database.
- Use a column whose values are evenly distributed as the distribution key, and a column whose values are of the TIME type as the partition key. For more information, see Schema design.
- Several columns of data in Summary table of commodity sales show that their distribution by document number is relatively random. JOIN operations are performed in market basket analysis based on document numbers. Therefore, the document number column is used as the partition key. Date is selected as a level-2 partition because no data will be imported to this column. The lifecycle is set to 100.
- Execute the following statement to create a table:
Create Table `demo_sales` ( 'Date' date, 'City' varchar, 'Document No' varchar, 'Store name' varchar, 'Commodity class' varchar, 'Commodity name' varchar, 'Province' varchar, 'Cost' double, 'Gross profit' double 'Quantity' bigint, 'Sales' double, ) DISTRIBUTE BY HASH ('Document No') PARTITION BY VALUE ('Date') LIFECYCLE 100 INDEX_ALL='Y' STORAGE_POLICY='COLD' COMMENT='Summary table of merchandise sales'
- After the table is created, use Kettle to import the local data in Excel format to
the AnalyticDB for MySQL database.
- For more information about how to use Kettle, see Use Kettle to synchronize local data to AnalyticDB for MySQL.
- After the data is imported, execute the
SELECT COUNT(*) FROM demo_ordersstatement. 40514 entries are returned.
- Create self-service datasets in FineBI.
- In the navigation pane, choose . Add a business package named adb.
- Create self-service datasets in the business package, and select the AnalyticDB connection_demo_sales fields (all fields of the demo_sales table in the AnalyticDB for MySQL database.
- Add data by referencing examples in FineBI documentation to generate the required dashboard. For more information, see market basket analysis.
- No external database is selected during initialization. After initialization, I want
to configure the external database.
- Start the data-based decision system. Choose General tab, click To Be Configured. . On the
- Enter the parameters of the external database.
- After the external database is configured, click Enable New Database.
- An external MySQL database is configured, but data import fails.
- Check the version and encoding method of the MySQL database. For more information, see Configure external MySQL database. FineBI supports MySQL 5.x.
- Check whether the MySQL database uses the utf8 (UTF-8 unicode) character set encoding
method, or execute the
CREATE DATABASE finedb CHARACTER SET utf8statement to create a new utf8-encoded database.
- An external AnalyticDB for MySQL database is configured, but connection to it fails.
Solution: The external database must be a MySQL database, instead of an AnalyticDB for MySQL database.
- No option is available to extract data or real-time data in the Data Preparation hierarchy
Solution: The version downloaded from the FineBI official website does not support direct connections to the AnalyticDB for MySQL database. You must contact FineBI technical support engineers to obtain the required version. For more information, see Solution.
- Data is not synchronized between FineBI and the AnalyticDB for MySQL database.
Solution: For more information, see Section 3.2 in Real-time data.
- No data is displayed after I update data.
Solution: If no data is displayed in a single row, the calculation result of the row may be null. If no data is displayed in the entire column and a function is used on the column, the function may be incompatible in AnalyticDB for MySQL. Contact AnalyticDB for MySQL technical support engineers.
- I fail to preview or save data.
- First, check whether a function is used on the column, but the column data types are supported by the function and invalid values exist after column data is converted. For example, AnalyticDB for MySQL will report an error if you enter the Chinese charters of city in a column. AnalyticDB for MySQL is used to find absolute values of numeric fields. The value is invalid when the Chinese charters of city are converted to a numerical value.
- If the error message contains a string of numbers as shown in the following figure, it is highly probable that the error is reported in AnalyticDB for MySQL. You can provide the string of numbers (it is a process ID) to AnalyticDB for MySQL technical support engineers for troubleshooting.
- If the error message contains only an error code, it is highly probable that the error is reported in FineBI. For more information, see FineBI errors.
