Could you build this?
No Developing a multidimensional calculation engine (OLAP/modeling engine) without cell formulas requires deep computer science expertise in dimensional data modeling, hypercube execution engines, and query compilation.
What it would actually take: Requires writing a high-performance in-memory calculation core in C++, Rust, or Go using columnar data structures and sparse multidimensional array algebra (similar to Anaplan or TM1). The core challenge lies in building a formal domain-specific language for business rules, an abstract syntax tree compiler, and an incremental dependency calculation engine capable of recalculating millions of multidimensional intersections in milliseconds.
Discussion
6 comments analyzed.
Competitors mentioned: IBM TM1, Anaplan, Python/NumPy, Traditional spreadsheets, Excel
Concerns raised: Data input is cumbersome and requires a lot of typing, Unclear if functions like sum/product fully work on slices, AI-generated code correctness cannot be guaranteed, 'Cube' terminology has confusing 3D connotations, Early alpha stage - still proof of concept
Feature requests: CSV and other data import formats, Python/NumPy-style multi-dimensional array notation for data entry, Data entry via 2D grid view (slice editing like spreadsheets), More spreadsheet functions for slice operations, Better UX/UI for rule editing workflows
