System Architecture البنية

Seven engines. One workspace.

A secure Flask backend paired with a fully responsive, framework-free JavaScript frontend delivers a desktop-grade data-preparation experience directly in the browser.

Backend Server

Flask application handling routing, session security, permission enforcement, and the CSV upload endpoint.

Data Parsing Layer

Delimiter sniffing, 19-class type inference, and index-mapped row formatting for compact network payloads.

Cleaning Engine

Whitespace, casing, fill/blank, fuzzy clustering, sandboxed expression transforms, and Unicode/Arabic/date/number/currency normalization.

Schema Engine

Split, join, derive, rename, remove, and move column operations — with facets and rules cleaned up automatically.

Facet Engine

Numeric bins, box-plot statistics, scatterplot coordinates, duplicate detection, and text filtering — computed server-side.

Database Layer

Parameterized queries with automatic MySQL-to-SQLite fallback and schema self-upgrade on startup.

Frontend Controller

A 5,500+ line asynchronous single-page state machine covering the grid, facets, validation, statistics, DQ scoring, history, and administration UI.

Intelligent Ingestion الاستيعاب الذكي

19-class automatic type inference

Uploads are sniffed for delimiter, stripped of blank rows, and converted to a compact index-mapped structure. Then every column's first 100 non-empty values run through a cascade of pattern detectors.

70% confidence threshold — if any single type reaches 70% across the sample, the column is classified and pre-seeded with a sensible default rule set. Every upload is logged to the database and a local audit CSV.

Quality Scoring مؤشر الجودة

The 10-dimension Data Quality Index

A defensible, quantified quality score — the equal-weighted average of ten dimensions, rendered as color-coded progress bars and exportable as CSV or a formatted PDF scorecard.

Completeness(Total − Missing) / Total × 100
Accuracy(Non-missing − Errors) / Non-missing × 100
Validity(Non-missing − Errors − Warnings) / Non-missing × 100
TimelinessShare of date values not in the future
ConsistencyAvg of casing + whitespace consistency
UniquenessDistinct non-missing / total non-missing × 100
Integrity(Total − Invalid) / Total × 100
PrecisionConsistency of decimal places or value length
Reliability25% Compl. + 25% Acc. + 20% Val. + 15% Cons. + 15% Integ.
Traceability100 if key/ID field, 85 if another key exists, else 50
