IBM solidDB is a relational database server that combines the high performance of in-memory tables with the nearly unlimited capacity of disk-based tables.
Pure in-memory databases are fast, but strictly limited by the size of memory. Pure disk-based databases allow nearly unlimited amounts of storage, but their performance is dominated by disk access. Even if the computer has enough memory to store the entire database in memory buffers, database servers that are designed for disk-based tables can be slow because the data structures that are optimal for disk-based tables are far from being optimal for in-memory tables. The solidDB solution is to provide a single hybrid database server that contains two optimized engines inside it:
- The main-memory engine (MME) is optimized for in-memory access.
- The disk-based engine (DBE) is optimized for disk-based access.
Both engines coexist inside the same server process, and a single SQL statement can access data from both engines.
MySQL is an open-source relational database management system (RDBMS) owned by Oracle. Before Oracle acquired the product, it was completely free for users. After the merge, the solution started offering paid services with more features, alongside a free version. MySQL can easily integrate with a wide variety of programming languages, which makes it one of the most flexible and reliable products among its competitors. This cost-effective solution helps users deliver high-performance and scalable database applications through several products. They include:
-
MySQL HeatWave: This is an in-memory query accelerator for MySQL. It is a parallel, columnar, hybrid query-processing engine with algorithms for distributed query processing. This database service is used for transactions, analytics, and machine learning (ML). It offers simplified, secure real-time analytics. It can be deployed on Oracle Cloud Infrastructure (OCI), Amazon AWS, Azure, and users' data centers.

SAP HANA, also known as SAP High-performance Analytics Appliance, is a multi-model database that stores data in its memory, allowing users to avoid disk storage. The product combines its robust database with services for creating applications. SAP HANA is faster than other database management systems (DBMS) because it stores data in column-based tables in main memory and brings online analytical processing (OLAP) and online transaction processing (OLTP) together.
The column-oriented in-memory database design allows users to run high-speed transactions alongside advanced analytics, all in a single system. This provides companies with the ability to process very large amounts of data with low latency and query data in an instant. By combining multiple data management capabilities, the solution simplifies IT, helps businesses with innovations, and facilitates digital transformation.
The solution is structured into five groups of capabilities, categorized as:
- Database design
- Database management
- Application development
- Advanced analytics
- Data virtualization
There are three more SAP products that work alongside SAP HANA and complete the experience for users together. SAP S/4HANA Cloud is a ready-to-run cloud enterprise resource planning (ERP). SAP BW/4HANA is a packaged data warehouse, based on SAP HANA, which allows users to consolidate data across the enterprise to get a consistent view of their data. Finally, SAP Cloud is a single database as a service (DBaaS) foundation for modern applications and analytics across all enterprise data. All three products can combine with SAP HANA to deliver to users an optimized experience regarding their data.
