Standalone Mode

ModeConfiguration modeConfig = createModeConfiguration();
Map<String, DataSource> dataSourceMap = ... // Building real data sources
Collection<RuleConfiguration> ruleConfigs = ... // Build specific rules
Properties props = ... // Build property configuration
DataSource dataSource = ShardingSphereDataSourceFactory.createDataSource(databaseName, modeConfig, dataSourceMap, ruleConfigs, props);
