Google Looker: A Unified Approach to Business Intelligence

The business intelligence (BI) market is growing unprecedentedly and is expected to cross USD 34 billion by 2028. According to a Statista report, investment in data and analytics is a top priority for over 87% of Chief Data Officers, Chief Data & Analytics Officers, and Heads of Data, Analytics, or AI. This is all very natural, as business intelligence is now a matter of strategic necessity and competitive differentiation.

At the end of the day, understanding all the data that your business generates is the only way to put it ahead of the competition. However, the challenge lies in making data insights accessible to a broader audience within the organization, regardless of their technical expertise. 

This is where Google Cloud’s Looker comes into play. Looker is a comprehensive data platform that combines data visualization with data modeling, exploration, and analytics capabilities. It offers a unified approach to business intelligence (BI) that democratizes data insights. Let’s explore how Looker empowers organizations to break down the dependencies and barriers that often exist between data analysts and decision-makers.

How Does Looker Handle Data?

Looker uses a universal semantic modeling layer. This layer offers a centralized location for governing and curating essential business metrics.  

Consider a global retail company with multiple branches and online platforms without a unified data model. Different departments may pull data from various sources, each with its own format and update schedule, leading to discrepancies in the figures. They might have different definitions or calculations for key metrics like “sales,” “revenue,” or “profit,” resulting in varied interpretations of the same data. Data silos can cause departments to have access to only a subset of the overall data, leading to incomplete or skewed data analysis.

Looker’s semantic layer solves this by standardizing metrics so everyone from the marketing team to the finance department sees the exact figures across the same parameters, leading to more cohesive decision-making.

Looker’s modeling layer also guarantees that information flows seamlessly across various tools and applications. For example, a multinational corporation can integrate data from multiple ERP and CRM systems while ensuring that executives have a comprehensive view of operations without data silos using Looker.

How Can Businesses Use Looker to Act on the Data?

Looker provides several capabilities that allow businesses to take action and operationalize their data directly within the platform.

• Alerts and Notifications

Looker allows users to set up data alerts and notifications based on specific conditions or thresholds defined in their data models or dashboards. These alerts can be configured to trigger emails, Slack messages, or other notifications when certain events occur or data falls outside of expected ranges. This enables businesses to proactively monitor key metrics and take immediate action when anomalies or critical situations arise.

• Data Actions

Users can create custom actions that can be executed directly from a dashboard or exploration. These actions can be simple tasks like sending an email or updating a record in a database or more complex workflows involving third-party integrations or custom code. For example, a user could create a Data Action to update a customer’s status in a CRM system based on their behavior data displayed in a Looker dashboard.

• Integration with Third-Party Applications

Looker offers robust APIs and integration capabilities, allowing businesses to seamlessly integrate Looker with other applications and systems within their technology stack. For example, Looker can be integrated with marketing automation platforms, enabling enterprises to trigger campaigns or personalized messaging based on customer data and insights discovered in Looker. Similarly, Looker can be integrated with business process management tools or workflow automation platforms to trigger specific actions or processes based on data conditions.

• Scheduling and Data Delivery

Looker allows businesses to operationalize their data workflows. Users can schedule recurring data extracts, reports, or dashboards to be generated and delivered via email, integrated content management systems, or other destinations. Without manual intervention, this capability enables businesses to streamline data-driven processes, such as regular reporting or data-driven email campaigns.

• Embedded Analytics and Custom Applications

Looker’s embedded data analysis capabilities enable businesses to directly incorporate interactive data experiences into their applications or customer-facing platforms. By embedding Looker dashboards, explorations, or custom-built data applications, companies can empower their users or customers to explore data, uncover insights, and take action within the context of their primary applications.

2. Enhancing Customer Segmentation in Finance

Consider a regional bank that aims to offer more personalized services and products but faces challenges because its data is siloed across different departments. The bank is finding it difficult to get a comprehensive view of customer behavior and preferences.

They can use Looker to-

• Integrate customer data from multiple sources, including transaction systems, customer service databases, and web analytics platforms
• Create a semantic layer so all departments use the same definitions and calculations for key metrics like customer value, engagement, and behavior patterns
• Build custom dashboards tailored for different roles within the bank, such as marketing, customer service, and product development teams
• Perform deep dives into customer data, identifying trends and patterns that were previously hidden, forecast customer behavior, and identify opportunities for cross-selling and upselling
• Use these insights to develop detailed customer personas and deliver personalized marketing campaigns

3. Improving Patient Care Coordination in Healthcare

For a large hospital network, coordinating patient care across multiple facilities and ensuring consistent treatment protocols can be difficult if the data isn’t integrated. They won’t be able to access comprehensive patient information, leading to inconsistencies in care and treatment.

Here, Looker can help in the following ways-

• Consolidate data from electronic health records (EHRs), treatment plans, and operational systems into a single platform where all relevant patient and operational data are accessible
• Standardize medical terminologies and treatment protocols across all facilities
• Doctors, nurses, and administrative staff can use Looker’s data exploration tools to easily retrieve patient histories, treatment effectiveness data, and operational metrics in real-time

Is Looker Better than Power BI or Tableau?

Answering this question with a simple ‘yes’ or ‘no’ would not do justice to the unique strengths each tool offers. Google’s Looker, Microsoft’s Power BI, and Salesforce’s Tableau are among the most powerful analytics and data visualization tools available today. Each one is embedded within a robust ecosystem and backed by the reputation of a leading enterprise known for its technological excellence. These tools are designed to meet diverse business needs, and their effectiveness depends on your specific requirements and context.

• Google Cloud’s Looker

It shines in cases where a company needs to create a unified view of business metrics across various data sources. It is a very strong semantic tool. Companies heavily using Google Cloud services can benefit from seamless integration. 

Looker does have a steep learning curve, as it uses LookML, a proprietary modeling language, to define data models and relationships. Users need to learn LookML to fully utilize Looker’s capabilities, which can be challenging. Organizations with a technically skilled workforce can easily leverage LookML for advanced data modeling. However, smaller organizations with basic reporting needs may find Looker’s capabilities excessive. 

• Microsoft Power BI

Businesses already invested in Microsoft products like Azure, SQL Server, and Office 365 should undoubtedly choose Power BI. However, companies not using the Microsoft ecosystem might not get the full value from its features.

It is also a decent choice for small to medium businesses looking for cost-effective BI solutions or for users who need an intuitive and easy-to-use tool with strong visualization capabilities. Organizations requiring very complex data modeling might find Power BI’s capabilities somewhat limited compared to Looker or Tableau.

• Salesforce’s Tableau

Tableau is best known for highly interactive and customizable visualizations. It also has flexible and powerful data handling capabilities suited for companies with complex data requirements. It will be wise to remember that Tableau has been reported to experience performance issues with very large datasets unless appropriately optimized. 

Businesses with the budget to support a premium BI tool can consider Tableau and Looker. However, higher costs can be a barrier for smaller organizations. Users who wish to leverage advanced features and customizations also face a semi-steep learning curve.
