Apa iku PostgreSQL lan kenapa milih?

Question

Accepted Answer

**PostgreSQL** ("Postgres") minangka database **object-relational** open-source sing kuat — dikenali kanggo standar compliance, reliability, extensibility, lan set fitur sing sugih. Iku salah siji saka database paling advanced lan populer, cocok saka aplikasi cilik nganti sistem skala gedhe.

## Apa sing nggawe Postgres istimewa

```text
✓ Open-source & free, with a permissive license and strong community
✓ ACID-compliant, highly reliable (battle-tested for critical data)
✓ Standards-compliant SQL + advanced features
✓ EXTENSIBLE — custom types, functions, operators, and extensions (PostGIS, etc.)
✓ Rich data types — JSON/JSONB, arrays, ranges, UUID, geometric, full-text search
✓ Powerful querying — window functions, CTEs, advanced indexing
✓ MVCC concurrency — readers don't block writers
✓ Scales well; supports replication and partitioning
```

## Roso saka fitur Postgres

```sql
-- JSONB (binary JSON, indexable), arrays, and more built in
CREATE TABLE products (
  id SERIAL PRIMARY KEY,           -- auto-incrementing id
  tags TEXT[],                      -- an ARRAY column
  attributes JSONB                  -- structured JSON data, queryable & indexable
);
SELECT * FROM products WHERE attributes @> '{"color": "red"}';   -- JSONB query
SELECT * FROM products WHERE 'sale' = ANY(tags);                  -- array query
```

Postgres lumantar saka SQL biasa — JSONB native, arrays, lan fitur sugih ngopisir.

## Postgres vs database liyane

```text
PostgreSQL → feature-rich, standards-compliant, extensible — great all-rounder,
             excels at complex queries, JSON, and advanced features
MySQL      → also popular; historically simpler, very fast for reads, widely hosted
SQLite     → embedded, file-based, zero-config — for local/small apps
→ Postgres is often preferred for serious applications needing advanced features,
  data integrity, and extensibility.
```

## Mengapa Penting

Ngerti PostgreSQL penting amarga iku salah siji saka database populer lan kapabel, dipilih kanthi luas kanggo aplikasi serius, dadi ngerti apa iku lan kenapa dipriyoga minangka konteks berguna kanggo karya back-end lan data.

Kuatane utama Postgres — dadi **open-source lan gratis**, banget **reliable lan ACID-compliant** (dipercaya kanggo data kritis), **standards-compliant** kanthi fitur SQL advanced, **extensible** (custom types, functions, lan extensions kaya PostGIS kanggo data geospatial), lan menawarake **rich built-in data types** (utamane JSONB kanggo queryable JSON, arrays, lan full-text search) — nggawe dadi all-rounder kuat sing nangani kebutuhan relasional tradisional lan requirements modern (semi-structured JSON data, complex queries, geospatial, etc.).

**MVCC concurrency** ne (readers ora block writers) lan fitur scalability nambah cocok kanggo aplikasi demanding.

Ngerti fitur distinguishing Postgres (extensibility, JSONB lan rich types, advanced querying, reliability) lan cara compare karo alternatives (pilihan feature-rich, standards-compliant asring dipriyoga kanggo aplikasi serius, versus MySQL sederhana utawa SQLite embedded) ngjelaske kenapa akeh tim milih lan apa sing nggawe capable.

Amarga PostgreSQL minangka database dominant, highly-regarded dienggo ing industri, ngerti identity lan kuatane minangka pengetahuan dasar penting kanggo sapa wae sing kerja karo databases — iku asring default recommendation kanggo project anyar sing butuh database relasional robust lan feature-rich.
