1. Data Integration Approach: AtScale primarily focuses on connecting to a wide range of data sources, enabling users to access and analyze their data from various platforms seamlessly. Datameer, on the other hand, emphasizes a self-service approach to data integration, allowing users to transform, clean, and prepare data within the platform itself, reducing the need for external tools.
2. Data Modeling Capabilities: AtScale offers robust data modeling capabilities with its Semantic Layer, providing a unified view of data for analysis across multiple sources. Datameer, while also providing data modeling functionalities, is more geared towards providing agile data preparation and visualization solutions, allowing for quick insights to be gained from the data.
3. Scalability and Performance: AtScale is known for its ability to handle large datasets and complex queries, making it suitable for enterprise-level analytics with high performance. Datameer, on the other hand, excels in providing a user-friendly interface for agile analytics, focusing on ease of use and quick turnaround times for analysis tasks.
4. Advanced Analytical Features: AtScale offers advanced analytical features such as OLAP capabilities, machine learning integration, and granular security control for fine-tuning access to data. Datameer, while also capable of supporting advanced analytics, shines in its ability to provide intuitive visualization tools and data exploration functionalities for users of varying expertise levels.
5. Governance and Compliance: AtScale provides strong governance and compliance features, allowing administrators to manage access control, data lineage, and auditing processes efficiently. Datameer also offers governance capabilities but focuses more on empowering business users with self-service analytics while maintaining compliance with data regulations.
6. Cost and Licensing Model: AtScale typically follows an enterprise-grade licensing model, which may involve higher costs but provides comprehensive support and features. In contrast, Datameer offers flexible pricing options, including per-user licensing, making it more suitable for organizations looking for cost-effective solutions with scalable user accessibility.

In Summary, AtScale and Datameer differ in their data integration approach, data modeling capabilities, scalability, performance, advanced analytical features, governance, and compliance, as well as cost and licensing models to cater to different enterprise needs.
