DA-bench

What is DA-bench?

DA-bench is the “Data Analyst Benchmark” - it is a series of questions that you would expect Data Analysts to be able to solve.

This benchmark was created to help us test Unsupervised and other data tools against real-world problems, so we can understand the strengths and weaknesses of various approaches to automating analytics.

DA-bench is a visual benchmark, you can see both the score and videos of how every tool performs on every test. See some examples below:

X

Databricks Assistant answering a data querying question that tests performing an aggregation by a different name and a second query from that (DQ19).

X

Unsupervised answering a data querying question that tests ambigious column names (DQ15)

X

Snowflake Cortex Analyst answering a data query question that tests multiple joins for the same tables across filters and stats (DQ27).

X

Tableau Agent answering a data query question designed to find and compare information of ambiguous types across tables without joins (DQ4).

X

Databricks Genie answering a Visualization question that requires charting two series (V2).

X

Snowflake Copilot returning a hallucination to a feature engineering question designed to test minmax normalization (FE3). Snowflake renormalizes a subset of the column values rather than just returning the requested normalized values.

X

Google Gemini in BigQuery answering an insight identification question that compares an aggregation for two distinct subsets of data (II2).

About

The Data Analyst Benchmark is a collection of datasets and prompts that can be used to test how automated analytics tools handle common data analyst tasks.

We use this information to help us prioritize work to improve our AI. We are making it available publicly to help other companies improve their tools and to help users evaluate which tools are relevant to their problems.

DA-bench currently tests dozens of prompts across 9 categories. Evaluation is performed by manual testing by a third-party, scores and videos of test results are displayed on dabench.com.

Test Scoring

Each test question is worth a maximum of 5 points. Deductions are made as follows:
