Opensee vs. Other Solutions

Dive deeper into data. Click the tabs to discover how Opensee Enterprise is pushing the boundaries of self-service data analytics for financial institutions and how we stand out from traditional solutions.

In Memory

  • Limited scalability: restricted to either select a few days of history or granularity of data
  • Segment data sets in different cubes, no cross data sets queries possible
  • Expensive hardware (RAM)
  • Complex to run on large distributed infrastructures
  • Not fault tolerant

Opensee key differences

  • On-disk deployment
  • Fault tolerant and scalable at low cost (just add commodity hardware)
  • Allows for full granularity with any depth of history
  • Enables cross data sets queries
  • Still matches "In-memory" performance
  • Total user autonomy with all required functionalities
  • Ease of integration in FI architectures

Traditional and Cloud data warehouse limitations

  • Generalist approach: technology not focused on financial institutions specific use cases
  • Lower performance
  • Cloud-based solutions = data hosting regulation issues
  • Pure technology stack: not ready to use by business end users
  • Not designed to support what-if scenarios

Opensee key differences

  • On-premise, cloud, multi cloud or hybrid deployment
  • 100X faster even against high performance and popular data warehouses on finance specific use cases
  • Integrated FI features (on the fly currency conversion …)
  • Native support of what-if scenarios

Data warehouse accelerator limitations

  • Requires pre-calculated aggregates at multiple levels of dimensional hierarchies
  • Inability to meet data model adjustments and maintenance requirements
  • Requires to guess pre-determined usage only
  • Multiplies the size of original data set
  • Not adapted to real-time data insertion and updates - cache invalidation problem
  • Slow access to raw data

Opensee key differences

  • High performance without pre-aggregations
  • Maintain aggregation flexibility, access to raw level, ability to insert real time and access this data instantaneously
  • Allows to add columns with simple database filters
  • Total user autonomy with all required functionalities
  • Ease of integration in FI architectures
