■About Snowflake
Snowflake is a cloud data platform used by thousands of companies in numerous
industries.(*2) Using Snowflake’s data cloud, siloed data is integrated and can be safely
extracted and shared to promote data applications and even implement a variety ofAI/ML models and analytical workloads. In addition, it provides a singular consistentexperience across clouds and regions regardless of where the data or users are located.
■Service backgroundIn recent years, the importance of data-driven marketing initiatives has grown, drawing
more focus on data cleanrooms, data exchanges and other data analysis environmentsthat take user privacy into consideration. In the past, data utilization was hindered byinsufficient data for analysis in terms of both volume and quality and a lack of analyticaloperational knowledge. Many companies are striving to resolve these issues through DX
of data infrastructures and are considering implementing cloud data platforms.
Until now, DAC has been offering reporting services utilizing AudienceOne®. However,with advances in data infrastructures due to DX as mentioned above, more companies
are expressing a desire to conduct data analysis on their own, to conduct log-level
analyses, or to make estimates or forecasts using log data. To respond to these needs,
DAC has decided to develop services that use Snowflake, a cloud data platform that
securely integrates and shares data and has been adopted by numerous companies bothin Japan and overseas.
■Service summary and characteristics
For the first phase of the rollout, DAC will reinforce and expand the breadth of its
AudienceOne® data analysis services by integrating first-party data and creating anenvironment where client companies can use Snowflake to perform in-depth data
aggregation, effect forecasting, and other forms of data analysis more flexibly.

1. Advanced data aggregation and analysis using client company website
behavioral log data and AudienceOne® data
Company website behavioral log data acquired using AudienceOne® tags andthird-party data owned by AudienceOne® (data on estimated attributes, interests, etc.)
can be used on a log level. This enables advanced data aggregation and analysis,
forecasts using machine learning, and optimized ad deliveries. Because data
integration or other forms of data pre-processing is not required, data analysis can beconducted and utilized immediately.
2. Template queries and reader accounts(*3)
Using DAC’s template queries, users can analyze data without SQL or other codeknowledge. Template queries enable calculations of CV probability and other statistics
for forecast analysis. Companies that have adopted Snowflake can combine third-party
data owned by AudienceOne® with their own company data in the Snowflake
environment for further analysis. Companies that have yet to adopt Snowflake can also
do this by using DAC’s reader account to create a Snowflake environment.
3. Support provided by DAC data analysts
For advanced analysis that goes beyond template queries, DAC will provide support
from data analysts who are experienced in building machine learning models in thedigital advertising field. In addition to analytical skills, we can also provide feedback
and other support regarding analytical results.
DAC will continue to develop services that are linked with Snowflake Marketplace orutilize Streamlit in Snowflake(*4) to contribute to our client companies’ marketing
