Kyvos is a semantic layer for AI and BI. It provides: 1. Unified Semantic Foundation for AI and BI- Kyvos semantic layer standardizes how metrics, KPIs, dimensions, hierarchies, relationships, calculations, and business rules are modelled across the enterprise — so that dashboards, analytics tools, notebooks, and AI systems all operate on the same understanding of the business. It enables: - Shared semantics — one common data language across every tool, team, and system - Governed access — data exploration within defined security, role, and permission boundaries - Platform interoperability — consistent semantic context across diverse platforms and environments - AI readiness — LLMs and agents work with governed business semantics rather than raw tables or ambiguous schema 2. AI Grounded in Business Context Kyvos grounds AI systems in the governed semantic model, ensuring they operate on established business context rather than raw schemas — improving the accuracy, traceability, and reliability of AI-generated insights. 3. Consistent Metrics Across BI Tools Kyvos centralizes metric and KPI definitions in the semantic layer and applies them consistently across every analytics interface — eliminating metric drift and improving trust in analytics. 4. High-Performance Analytics at Scale, enabling: - Sub-second query performance across massive datasets - High concurrency across thousands of users and workloads - Consistent response times regardless of data volume or concurrency - No performance degradation as adoption grows 5. Multidimensional Analytics on the Cloud: - Granular analysis across billions of rows - Thousands of measures and dimensions in a single model - Fast drill-down across complex hierarchies - Full analytical depth without sacrificing query speed 6. Cloud Cost Efficiency-Kyvos serves analytics through its semantic layer, reducing compute use and enabling users, workloads, and analytics to scale without increasing cost

The intelligent semantic layer integrates data with its relevant business context and interrelationships, streamlining metrics and accelerating the creation of data products by enabling SQL queries that are up to 90% shorter. This empowers users to model the data using terms they are familiar with, fostering a shared comprehension and aligning metrics with organizational goals. By establishing semantic relationships that take the place of conventional JOIN operations, queries become far less complex. Hierarchies and classifications are employed to deepen data understanding. The system ensures automatic alignment of data with the semantic framework, facilitating the merger of different data sources through a robust distributed SQL engine that accommodates large-scale queries. Data is accessible in the form of an interconnected semantic graph, enhancing performance and decreasing computing costs via an advanced caching mechanism and materialized views. Users benefit from advanced query optimization strategies. Furthermore, Timbr facilitates connections to an extensive array of cloud services, data lakes, data warehouses, databases, and various file formats, providing a smooth interaction with data sources. In executing queries, Timbr not only optimizes but also adeptly allocates the workload to the backend for enhanced processing efficiency. This all-encompassing strategy guarantees that users can engage with their data in a more effective and agile manner, ultimately leading to improved decision-making. Additionally, the platform's versatility allows for continuous integration of emerging technologies and data sources, ensuring it remains a valuable tool in a rapidly evolving data landscape.

When implemented as an on-premises server, SQL Server Analysis Services offers extensive support for multiple model types, such as tabular models at different compatibility levels depending on the version, multidimensional models, data mining features, and Power Pivot functionalities for SharePoint. The typical implementation process consists of establishing a SQL Server Analysis Services instance, creating either a tabular or multidimensional data model, deploying this model as a database to the server instance, processing it to fill it with data, and setting up user permissions to enable data access. After this setup is finalized, client applications compatible with Analysis Services can readily access the data model as a source. These data models often aggregate information from external systems, primarily retrieving data from data warehouses that utilize SQL Server or Oracle relational database engines; however, tabular models are also capable of connecting to various other data sources. This flexibility and range of capabilities underscore the strength of SQL Server Analysis Services as a formidable resource for analytics and business intelligence, allowing organizations to derive meaningful insights from their data. Ultimately, such robust functionality positions SQL Server Analysis Services as an essential component for enterprises aiming to enhance their analytical capabilities.
