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:
Both engines coexist inside the same server process, and a single SQL statement can access data from both engines.
The OmniSci platform is designed to overcome the scalability and performance limitations of legacy analytics tools faced with the scale, velocity and location attributes of today’s big datasets. Those tools are collapsing, becoming too slow and too hardware-intensive to be effective in big data analytics. OmniSci is a breakthrough technology, originating from MIT, designed to leverage the massively parallel processing of GPUs alongside traditional CPU compute, for extraordinary performance at scale.
IBM solidDB is ranked 30th in Relational Databases while OmniSci is ranked 31st in Relational Databases. IBM solidDB is rated 0.0, while OmniSci is rated 0.0. On the other hand, IBM solidDB is most compared with SQL Server, MySQL, MariaDB and IBM Db2 Database, whereas OmniSci is most compared with Kinetica, SingleStore DB and SQream DB.
