The Ultimate BI tool

With Ultibi you can turn your DataFrame into a pivot table with a UI and share it across organisation. You can also define measures applicable to your DataFrame. This means your colleagues/consumers don't have to write any code to analyse the data.

Ultibi leverages on the giants: Actix, Polars and Rust which make this possible. We use TypeScript for the frontend.

Examples

Our userguide

Python

pip install ultibi

Quickstart

import ultibi as ul
import polars as pl
import os
os.environ["RUST_LOG"] = "info" # enable logs
os.environ["ADDRESS"] = "0.0.0.0:8000" # host on this address

# Read Data
# for more details: https://pola-rs.github.io/polars/py-polars/html/reference/api/polars.read_csv.html
df = pl.read_csv("titanic.csv")

# Convert it into an Ultibi DataSet
ds = ul.DataSet.from_frame(df)

# By default (might change in the future)
# Fields are Utf8 (non numerics) and integers
# Measures are numeric columns.
ds.ui() 

Then navigate to http://localhost:8000 or checkout http://localhost:8000/swagger-ui for the OpenAPI documentation.

More flexible - custom measures

import ultibi as ul
import polars as pl
import os
os.environ["RUST_LOG"] = "info" # enable logs
os.environ["ADDRESS"] = "0.0.0.0:8000" # host on this address

# Read Data
# for more details: https://pola-rs.github.io/polars/py-polars/html/reference/api/polars.read_csv.html
df = pl.read_csv("titanic.csv")

# Let's add some Custom/Bespoke Calculations to our UI

# Standard Calculator
def survival_mean_age(kwargs: dict[str, str]) -> pl.Expr:
    """Mean Age of Survivals
    pl.col("survived") is 0 or 1
    pl.col("age") * pl.col("survived") - age of survived person, otherwise 0
    pl.col("survived").sum() - number of survived
    """
    return pl.col("age") * pl.col("survived") / pl.col("survived").sum()

# Also a Standard Calculator
def example_dep_calc(kwargs: dict[str, str]) -> pl.Expr:
    return pl.col("SurvivalMeanAge_sum") + pl.col("SouthamptonFareDivAge_sum")

# When we need more involved calculations we go for a Custom Calculator
def custom_calculator(
            srs: list[pl.Series], kwargs: dict[str, str]
        ) -> pl.Series:
        """
        Southampton Fare/Age*multiplier
        """
        df = pl.DataFrame({"age": srs[0], 
                           "fare": srs[1],

        multiplier = float(kwargs.get("multiplier", 1))
        res = df["S"] * df["fare"] / df["age"] * multiplier
        return res

            ul.BaseMeasure(
                "SouthamptonFareDivAge",

                    custom_calculator, res_type, inputs, returns_scalar
                ),
                # (Optional) - we are only interested in Southampton, so
                # unless other measures requested we might as well filter for Southampton only
                # However, if if multiple measures requested, their precompute_filters will be joined as OR.
                [[ul.EqFilter("embarked", "S")]],
                # PARAMS tab of the UI
                calc_params=[ul.CalcParam("mltplr", "1", "float")]
            ),
            ul.BaseMeasure(
                "SurvivalMeanAge",

        ]

# Convert it into an Ultibi DataSet
ds = ul.DataSet.from_frame(df, bespoke_measures=measures)

# By default (might change in the future)
# Fields are Utf8 (non numerics) and integers
# Measures are numeric columns.
ds.ui() 

You can also wite Rust native Custom calculators measure which wouldn't be bounded by GIL! Checkout the userguide.

DataSources - In and OutOf memory

We provide aim to support different sources of the data.

scan = pl.read_csv("../frtb_engine/data/frtb/Delta.csv", 
                           dtypes={"SensitivitySpot": pl.Float64})
dsource = ul.DataSource.inmemory(scan)
ds = ul.DataSet.from_source(dsource)
ds.prepare() # .prepare() is only relevant to FRTB dataset currently
ds.ui()

If you don't want to/can't hold all your data in the process memory, you can sacrifise performance for memory with Scan/DataBase

import polars as pl
import ultibi as ul
# Note that the LazyFrame query must start with scan_
# and must've NOT been collected
scan = pl.scan_csv("../frtb_engine/data/frtb/Delta.csv", 
                    dtypes={"SensitivitySpot": pl.Float64})
dsource = ul.DataSource.scan(scan)
ds = ul.DataSet.from_source(dsource)
ds.ui()

Note: Naturally the later two options will be slower, because prior to computing your measures we will need to read the relevant bits of the data into the process memory.

FRTB SA

FRTB SA is a great usecase for ultibi. FRTB SA is a set of standardised, computationally intensive rules established by the regulator. High business impact of these rules manifests in need for analysis and visibility thoroughout an organisation. Note: Ultima is not a certified aggregator. Always benchmark the results against your own interpretation of the rules. See python frtb userguide.
