In our data-centric era, grasping the nuances of data is crucial. The semantic model, as defined by Gartner, is a method that organizes data to reflect its inherent meaning and relationships. This not only aids in application development but also ensures data consistency.
A semantic model offers a business-centric view of data. Capturing data's semantic description, structure, and business form at a high level, it elevates data understanding. The semantic model, or the semantic data model as defined by Gartner, is essentially a method of organizing data that reflects the basic meaning of data items and the relationships among them. This organization makes it easier to develop application programs and to maintain the consistency of data when it is updated.
A semantic model always presents a business-user-friendly perspective of the data. Defined at a higher level, it captures your data's semantic description, structure, and business form, ultimately enhancing data comprehension.
While both terms are closely related, they serve distinct purposes:
Have you ever grappled with meaningless column names or struggled to translate underlying metadata into business terms? Every data practitioner has. These challenges underscore the importance of semantic models for business users.
To understand the situation mentioned above, let's consider a few scenarios. First, imagine you are a business user needing to access data from various channels. A semantic model can help you by providing a consistent data model with a logical framework that can be used across multiple sources.
Next, let's consider another scenario where you are a non-technical data producer. You might have data stored in different systems, and you need to make this data available to others in your organization. A semantic model can help you by providing a simple interface for accessing the data in a structured manner.
Navigating cryptic column names or translating metadata into business terms is a challenge many face. Semantic models address these issues, streamlining data access and interpretation for business users. But beyond these immediate benefits, what are the core competencies that make semantic models indispensable in the world of data analytics?
Semantic models offer shared business logic, quick insights for complex queries, a unified security strategy, and high-performance engine capabilities. These competencies not only enhance the user experience but also ensure that businesses can leverage data more effectively and efficiently.
By providing a semantic model, different business departments within a company can share the same business logic. This eliminates the need to separately develop semantic information with BI tools and data applications. The semantic model acts as a consistent business model that maps complex data into clear business terms. This creates a unified semantic model where dimensions, measures, and hierarchies, etc., are synchronized to enhance business semantics over technical data and facilitates various analyses for business people.
Data analysts can provide business users with straightforward insights into efficient performance by defining time intelligence functions, typically like YOY (year-on-year) and YTD (year-to-date). In addition, decision makers can easily manage complex analysis scenarios involving multiple fact tables, many-to-many relationships, and semi-additive measures through semantic models.
Semantic models allow enterprises to reduce data security risks by centralizing user and data access management at the data asset layer of the platform. This configuration carries over to all business applications at the upper layers, thus eliminating the need for IT personnel to configure extra data access controls for downstream systems. Ultimately, this prevents data from being spread across different business systems and reduces associated security risks.
By leveraging an underlying distributed cluster, semantic models can greatly improve overall query speed even across many dimensions and large volumes of data. Additionally, caching frequently used data helps to reduce access time and improve the overall experience. As a result, enterprise teams can enjoy stable and superior performance while using semantic models.
Having explored the competencies of the semantic model, it's essential to remember the distinction between the model and the layer. While the semantic model provides the conceptual understanding of data, the semantic layer offers the tangible interface for users to interact with that data. With this in mind, let's delve into the typical implementations of semantic layers.
Building an effective semantic layers requires the right placements. Gartner categorizes common semantic layers into the following three types in their report "Demystifying Semantic Layers for Self-Service Analytics":
In the rapidly evolving landscape of data analytics, the adoption of a semantic layer has become more than just a trend—it's a necessity. A recent poll conducted by Gartner, a leading research and advisory company, sheds light on this pressing need. The poll titled "Have you considered using a universal semantic layer in your analytics architecture?" garnered responses from 118 participants, revealing the following insights:
These numbers underscore the growing recognition of the value a semantic layer brings to analytics architecture. Modern data architectures require a semantic layer to ensure precision, reusability, reliability, and cost-effectiveness. It abstracts and augments metrics and other semantic components, allowing business users to consume and explore data without needing to be technical data pipeline experts. Moreover, a semantic layer provides a governed, curated metrics data mart, enabling business users, data analysts, and data scientists to focus more on insights and less on backend table structures.
The increasing inclination towards the adoption of a semantic layer is a testament to its critical role in modern data analytics. As businesses grapple with diverse data sources and the challenges they pose, the semantic layer emerges as a solution that bridges the gap between complex data structures and comprehensible insights.
With the rise of various tools and concepts, the approaches to implementing semantic Models in enterprises have also evolved. Over time, there has been a convergence trend between BI tools emphasizing self-service analytics and semantic layers focusing on centralized governance. According to Gartner's report, the drive toward this convergence of capabilities has several prevailing themes:
While these three types of semantic layers each have unique benefits, they also come with a common set of challenges. In many cases, enterprises struggle with enabling business users to define and maintain metrics in a self-service fashion, while ensuring IT-centric data governance. As a result, there's an increasing need for a solution that can overcome this obstacle, which is where the concept of a Metrics Platform comes into play.
Metrics are powerful. Almost any behavior can be distilled into specific, trackable metrics, making them more engaging than mere tables for businesses. Therefore, businesses often find metrics more engaging than tables. Metrics provide the most user-friendly presentation and yield values that can be directly perceived and more effectively drive the realization of business goals. This scenario exemplifies a typical metrics-driven approach.
A metrics-driven strategy is particularly effective in constructing semantic models. By refining and consolidating business information into a uniform manner, metrics can communicate crucial data to business users or data producers more effectively. Semantic models must evolve to better serve metrics-driven businesses. This approach aids businesses in understanding their performance and making metrics-driven decisions.
Based on years of experience working with valued customers, Kyligence has incorporated a metrics-driven approach to construct a semantic model. This led to the creation of a metrics platform called Kyligence Zen.
