PROSES PENGEMBANGAN PERANGKAT LUNAK (END-TO-END SDLC)

Pengembangan perangkat lunak bukan sekadar coding, tetapi proses rekayasa sistem yang terstruktur dan terdokumentasi.

Secara umum mengikuti tahapan:


Problem Identification
↓
Requirement Engineering
↓
SRS
↓
System Analysis
↓
Architecture Design
↓
Database Design
↓
Backend & Frontend Design
↓
Integration
↓
Testing & Deployment

1️⃣ IDENTIFIKASI MASALAH

🎯 Tujuan

Memahami masalah bisnis sebelum menulis satu baris kode pun.

🔍 Aktivitas

Observasi proses bisnis
Interview stakeholder
Identifikasi pain point
Analisis gap sistem lama

📌 Output

Problem statement
Business objective
High-level solution

⚠️ Prinsip Penting

Jangan langsung menawarkan solusi teknis sebelum memahami masalah bisnis.

2️⃣ REQUIREMENT GATHERING

Tahapan mengumpulkan kebutuhan sistem dari stakeholder.

🎭 Stakeholder

User
Owner
Admin
IT team
Regulator

🛠 Metode

Interview
Workshop
Kuesioner
Prototyping
Observasi lapangan

📌 Output

Daftar kebutuhan sistem
Prioritas kebutuhan
Dokumen requirement awal

3️⃣ SRS (Software Requirements Specification)

SRS adalah dokumen formal yang menjelaskan apa yang harus dilakukan sistem, bukan bagaimana caranya.

📑 Struktur Umum SRS

1. Pendahuluan

Tujuan dokumen
Ruang lingkup sistem
Definisi istilah

2. Deskripsi Umum

Perspektif produk
Karakteristik pengguna
Batasan sistem

3. Functional Requirements

Contoh:

ID	Requirement
FR1	Sistem harus memungkinkan user login
FR2	Sistem harus menyimpan transaksi

4. Non-Functional Requirements

Kategori	Contoh
Performance	Response < 2 detik
Security	Enkripsi password
Availability	99% uptime
Scalability	10.000 user concurrent

5. Use Case Specification

Menjelaskan interaksi user dengan sistem.

📌 Output

Dokumen SRS lengkap (baseline kontrak antara client dan developer).

4️⃣ ANALISIS SISTEM

Tahapan menguraikan requirement menjadi model sistem.

🎭 Identifikasi Aktor

Primary actor
Secondary actor

🔄 Use Case Analysis

Menentukan:

Main success scenario
Alternate flow
Exception flow

📊 Activity Diagram (Deskriptif)


User Login
↓
Validasi
↓
Akses Dashboard

⚠️ Constraint Analysis

Budget
Timeline
Infrastruktur
Regulasi

5️⃣ PERANCANGAN ARSITEKTUR SISTEM

Menentukan struktur teknis sistem.

📌 Pilihan Arsitektur

Arsitektur	Kapan digunakan
Monolith	Sistem kecil-menengah
MVC	Web application
Microservices	Enterprise & scalable
Clean Architecture	Maintainability tinggi

🏗 Client-Server Model


Client (Browser)
    ↓
Application Server
    ↓
Database Server

🌐 REST Architecture

Karakteristik:

Stateless
JSON-based
HTTP method (GET, POST, PUT, DELETE)

☁ Deployment Model

On-premise
Cloud (AWS/GCP/Azure)
Containerized (Docker)
CI/CD pipeline

6️⃣ DESAIN DATABASE

Database design bertujuan memastikan:

Konsistensi data
Integritas relasi
Efisiensi query

📊 ERD (Konsep)


User (1) ────< Order (1) ────< OrderDetail >──── (1) Product

📌 Normalisasi

1NF → Data atomic
2NF → No partial dependency
3NF → No transitive dependency

📌 Contoh Struktur Tabel

Users

id (PK)
name
email (unique)
password_hash
role

7️⃣ DESAIN BACKEND

Backend bertanggung jawab pada:

Business logic
Validasi
Data processing
Security

📌 Pilihan Teknologi

Node.js + Express
Java Spring Boot
PHP Laravel
Python Django

📂 Struktur MVC


/controllers
/models
/routes
/middlewares
/config

📌 Contoh Endpoint


GET    /api/products
POST   /api/login
POST   /api/orders

🔐 Security Layer

JWT authentication
Password hashing (bcrypt)
Role-based access control
Input sanitization

8️⃣ DESAIN FRONTEND

Frontend bertanggung jawab pada:

UI/UX
Interaksi user
Integrasi API

🎨 UI/UX Principle

Simplicity
Consistency
Accessibility
Responsive design

📌 Arsitektur Frontend

Multi-page application
SPA (Single Page Application)

Modern enterprise → SPA (React/Vue/Angular)

📦 Komponen

Navbar
Form
Table
Modal
Dashboard

🔄 Integrasi API


fetch('/api/products')
.then(res => res.json())
.then(data => render(data));

9️⃣ INTEGRASI SISTEM

Menjamin komunikasi antar layer berjalan baik.

🔁 Alur Request-Response


Frontend → HTTP Request → Backend
Backend → Query DB → Response JSON
Frontend → Render UI

📦 Struktur JSON Standar


{
  "status": "success",
  "data": {},
  "message": ""
}

🔟 TESTING STRATEGY

Testing dilakukan berlapis.

🧪 1. Unit Testing

Mengujicoba fungsi secara individual.

Contoh:

Validasi login
Perhitungan total transaksi

🔗 2. Integration Testing

Mengujicoba antar modul:

API ↔ Database
Frontend ↔ Backend

👥 3. System Testing

Menguji sistem secara keseluruhan.

✔ 4. User Acceptance Testing (UAT)

Checklist berbasis requirement di SRS.
