Data Modeling Patterns

Common Design Patterns

💡 Data, modeling, patterns, "READY-MADE, BLUEPRINTS" jaise, HAIN — COMMON, PROBLEMS, (jaise, HISTORICAL, DATA, YA, BADLE, HUE, ATTRIBUTES) ke, liye, PEHLE, se, TESTED, SOLUTIONS, HOTE, HAIN, HAR, BAAR, SCRATCH, se, SOCHNE, ki, ZAROORAT, NAHI.

Bucket, PATTERN, TIME-SERIES, DATA, (jaise, SENSOR, READINGS) ko, TIME-BASED, "BUCKETS" mein, GROUP, karta hai, HAR, DOCUMENT, ke, liye, EK, SEPARATE, DOCUMENT, banaне, ki, JAGAH — DOCUMENT, COUNT, KAAFI, KAM, ho, jaata hai.

Polymorphic, PATTERN, EK, HI, COLLECTION, mein, DIFFERENT-SHAPED, DOCUMENTS, RAKHNE, deta hai (jaise, DIFFERENT, TYPES, ke, "PRODUCTS" — BOOKS, aur, ELECTRONICS, ke, DIFFERENT, FIELDS, ho, sakte, hain, EK, HI, products collection, mein).

// Bucket pattern — sensor readings, HOUR-WISE, bucket mein:
{
  sensorId: "S123",
  hour: ISODate("2024-01-15T10:00:00Z"),
  readings: [
    { time: "10:00:15", value: 22.5 },
    { time: "10:00:30", value: 22.7 }
    // ... poore hour ki readings, EK document mein
  ]
}

// Polymorphic pattern:
{ type: "book", title: "...", author: "...", isbn: "..." }
{ type: "laptop", title: "...", ram: "16GB", processor: "..." }

⚡ Quick Recap

Bucket pattern = time-series data, ko, time-based, groups, mein, organize, karta hai
Polymorphic pattern = different-shaped documents, ek, hi, collection, mein
Ye patterns, common, real-world, problems, ke, liye, TESTED, solutions, HAIN

Attribute, pattern, SIMILAR, fields, (jaise, DIFFERENT, LANGUAGES, mein, product, name) ko, EK, ARRAY, OF, key-value, PAIRS, mein, CONVERT, karta hai, taaki, unpe, EASILY, INDEX/QUERY, kiya, ja, sake, bina, HAR, VARIANT, ke, liye, ALAG, field, banaye.

{
  name: [
    { locale: "en", value: "Laptop" },
    { locale: "hi", value: "लैपटॉप" }

}

Schema, evolve, hone, PAR, EK, "schema_version" field, ADD, karна, HELPFUL, hai — application, code, HAR, version, ko, ALAG, tareeke, se, handle, kar, sakta hai, MIGRATION, gradually, hone, deta, hai, bina, SAARE, documents, EK, saath, update, kiye.

💡Tip: Schema, versioning, KAAM, aata, hai, jab, EK, LARGE, collection, ka, migration, EK, saath, karna, IMPRACTICAL, hai — naye, documents, naye, schema, use, karte, hain, purane, gradually, update, hote, hain.
