Prepare BigQuery datasets and tables

To create AML AI datasets in an instance, you need to stage data in BigQuery within that Google Cloud project. The following sections show one way of preparing these datasets and tables.

Create a BigQuery output dataset

Run the following command to create a dataset to be used to send the pipeline outputs to BigQuery. In the following command, select a name for BQ_OUTPUT_DATASET_NAME that contains only letters (uppercase or lowercase), numbers, and underscores. You cannot use hyphens.

bq mk \
  --location=LOCATION \
  --project_id=PROJECT_ID \
  BQ_OUTPUT_DATASET_NAME

To see the AML AI outputs, see AML output data model.

Create the BigQuery input dataset

Create a BigQuery input dataset. Later, you will input your financial institution's transaction data into this dataset.

bq mk \
  --location=LOCATION \
  --project_id=PROJECT_ID \
  BQ_INPUT_DATASET_NAME

Create the BigQuery input dataset tables and upload the transaction data

We provide the AML input data model schema in the following formats:

• A single CSV file aml-input-data-model.csv with all tables included
• A single JSON file aml-input-data-model.json with all tables included
• Individual JSON files for each table (for example, account_party_link.json)

To download the JSON file for each table and use it to create the associated BigQuery table by applying the schema, run the following command.

for table in party account_party_link transaction risk_case_event party_supplementary_data
do
  curl -O "https://cloud.google.com/financial-services/anti-money-laundering/docs/reference/schemas/${table}.json"
  bq mk --table --project_id PROJECT_ID BQ_INPUT_DATASET_NAME.$table $table.json
done

Upload your financial institution's transaction data into the dataset tables. For more information, see any of the BigQuery quickstarts.

Grant access to the BigQuery datasets

The API automatically creates a service account in your project. The service account needs access to the BigQuery input and output datasets.

1. Install jq on your development machine. If you cannot install jq on your development machine, you can use Cloud Shell or one of the other methods for granting access to a resource found in the BigQuery documentation.

2. Run the following commands to grant read access to the input dataset and its tables.

   # The BigQuery input dataset name. You created this dataset and
   # uploaded the financial data into it in a previous step. This dataset should be
   # stored in the Google Cloud project.
   
   export BQ_INPUT_DATASET_NAME="BQ_INPUT_DATASET_NAME"
   
   # The BigQuery tables in the input dataset. These tables should
   # be part of the same project as the intended instance.
   # Make sure to replace each table variable with the appropriate table name.
   export PARTY_TABLE="PARTY_TABLE"
   export ACCOUNT_PARTY_LINK_TABLE="ACCOUNT_PARTY_LINK_TABLE"
   export TRANSACTION_TABLE="TRANSACTION_TABLE"
   export RISK_CASE_EVENT_TABLE="RISK_CASE_EVENT_TABLE"
   # Optional table
   export PARTY_SUPPLEMENTARY_DATA_TABLE="PARTY_SUPPLEMENTARY_DATA_TABLE"
   
   # Grant the API read access to the BigQuery dataset.
   # Update the current access permissions on the BigQuery dataset and store in a temp file.
   # Note: This step requires jq as a dependency.
   # If jq is not available, the file /tmp/mydataset.json may be created manually.
   bq show --format=prettyjson "PROJECT_ID:BQ_INPUT_DATASET_NAME" | jq '.access+=[{"role":"READER","userByEmail":"service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com" }]'> /tmp/mydataset.json
   # Update the BigQuery dataset access permissions using the temp file.
   bq update --source /tmp/mydataset.json "PROJECT_ID:BQ_INPUT_DATASET_NAME"
   
   # Grant the API read access to the BigQuery table if the table is provided.
   for TABLE in $PARTY_TABLE $TRANSACTION_TABLE $ACCOUNT_PARTY_LINK_TABLE $RISK_CASE_EVENT_TABLE $PARTY_SUPPLEMENTARY_DATA_TABLE ; do
     [ -n TABLE ] && bq add-iam-policy-binding \
       --member="serviceAccount:service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com" --role="roles/bigquery.dataViewer" \
       PROJECT_ID:BQ_INPUT_DATASET_NAME.${TABLE}
   done
   

3. Run the following commands to grant write access to the output dataset.

   # Note: This step requires jq as a dependency.
   # If jq isn't available, the file /tmp/mydataset.json may be created manually.
   bq show --format=prettyjson PROJECT_ID:BQ_OUTPUT_DATASET_NAME | jq '.access+=[{"role":"roles/bigquery.dataEditor","userByEmail":"service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com" }]'> /tmp/perms.json
   
   bq update --source /tmp/perms.json PROJECT_ID:BQ_OUTPUT_DATASET_NAME
