The document provides a metric weightage for evaluating various in-memory databases. It includes sub-metrics across various categories like storage, server type, use cases, benchmarks, integration, performance, operation, cost, and security. Each sub-metric is assigned a specific weightage based on its importance. Vendors like Oracle, SAP Hana, Kognitio, VoltDB, GridGain, MemSQL, SQLFire, and Altibase are then rated against each sub-metric to calculate a total score.
