Database Engine for SCADA/MES Systems

Product Specifications

Technical details and manufacturing context for Database Engine

Definition

The Database Engine is a specialized software component within a SCADA/MES Software Server that manages real-time and historical process data, equipment status, production records, and operational parameters. It provides data persistence, transaction management, query processing, and data integrity for manufacturing execution and supervisory control applications. The engine receives data from SCADA/MES applications through defined interfaces, organizes it into structured tables with relationships, optimizes storage for time-series data, executes queries using indexing and caching mechanisms, and ensures ACID properties for reliable data operations in industrial environments. Key parameters include support for SQL and NoSQL database types, maximum concurrent connections ranging from 1000 to 5000, data throughput of 10,000 to 100,000 transactions per second, query response time of 1 to 10 milliseconds, data compression ratio of 2:1 to 10:1, maximum database size of 1 to 100 TB, operating temperature range of -40 to 85 °C, storage interfaces such as SATA, SAS, and NVMe, memory usage of 512 to 4096 MB, CPU architecture support for x86 and ARM, redundancy support for Active-Passive and Active-Active configurations, and security encryption using AES-128 to AES-256 per ISO/IEC 18033-3. These values are reference ranges and must be verified with the manufacturer for specific models and applications. The engine is a component, not a standalone product, and its selection depends on system compatibility, data volume, and performance requirements. Always confirm model-specific specifications and standards with the legal manufacturer or supplier before procurement.

Working Principle

The database engine operates by receiving data from SCADA/MES applications through defined interfaces, organizing it into structured tables with relationships, optimizing storage for time-series data, executing queries using indexing and caching mechanisms, and ensuring ACID (Atomicity, Consistency, Isolation, Durability) properties for reliable data operations in industrial environments. It handles concurrent connections, manages transactions, and provides data compression to reduce storage costs. The engine supports various storage interfaces and CPU architectures, and can be configured for redundancy to ensure high availability. Its performance is characterized by data throughput, query response time, and memory usage, which must be matched to the deployment scale.

Frequently Asked Questions

What is the role of the Database Engine in SCADA/MES systems?

The Database Engine is a core software component that stores, retrieves, and manages data within SCADA/MES systems. It handles real-time and historical process data, equipment status, production records, and operational parameters, providing data persistence, transaction management, query processing, and data integrity for manufacturing execution and supervisory control applications.

What are the typical performance parameters for this Database Engine?

Typical reference ranges include 1000–5000 maximum concurrent connections, 10,000–100,000 transactions per second data throughput, 1–10 ms query response time, 2:1–10:1 data compression ratio, and 1–100 TB maximum database size. These values are indicative and must be confirmed with the manufacturer for specific models and deployments.

How does the Database Engine ensure data reliability?

The engine ensures ACID (Atomicity, Consistency, Isolation, Durability) properties, which guarantee that transactions are processed reliably. It also supports redundancy configurations such as Active-Passive and Active-Active to provide high availability, and uses security encryption (AES-128 to AES-256) to protect sensitive production data.

What factors should be considered when selecting a Database Engine for an industrial application?

Selection should consider compatibility with existing systems (SQL/NoSQL), data volume and throughput requirements, query response time, storage interface (SATA, SAS, NVMe), CPU architecture (x86, ARM), memory usage, operating temperature range, and redundancy needs. Always verify model-specific specifications and standards with the legal manufacturer or supplier.
