Data models, transactions and live product interactions
A serious backend is not only its HTTP routes. It also depends on persistence, guarantees and realtime flows.

Stack
6 items
Technologies, frameworks and tools grouped into one coherent engineering perimeter.
Topics
6 pages
Detailed documentation pages available from this parent ecosystem.
Model
2 sections
Decision blocks that explain how this ecosystem is used in real delivery.
01
Databases
PostgreSQL, MySQL and MongoDB according to the shape of the problem.
02
Typed access
Prisma for safer persistence contracts.
03
Realtime
Redis and Socket.IO for cache, state and live interactions.
The stack should communicate concrete engineering roles, not only names.
This parent page introduces the operational perimeter. It should help a client, recruiter or technical lead understand what the ecosystem is for before diving into individual topic pages.

01Persistence
Choose a data model that matches the business
Storage choices should reflect guarantees and use cases, not arbitrary taste.
Relational schemas, constraints, indexes and transactions.
Document models when flexibility is genuinely relevant.
Data access that remains understandable, testable and domain-aware.
02Realtime
Connect the backend to immediate experience
Realtime systems should stay reliable, modeled and observable.
Rooms, events, messages, presence and targeted broadcasting.
Cache, temporary state, rate limits and supporting services.
Chat, support, notifications and admin interfaces with live behavior.
Concrete pages below this ecosystem
Each card opens a dedicated technical page. The parent remains strategic and readable, while the child pages carry the detailed framework, tool or platform explanation.
01
DatabasePostgreSQL
PostgreSQL is a robust relational database for business data, transactions, constraints, indexes and demanding queries.
02
DatabaseMySQL
MySQL is a widely adopted relational database for web platforms, business applications and existing environments.
03
DatabaseMongoDB
MongoDB stores flexible documents, useful when the model evolves quickly but risky when data boundaries stay vague.
04
DatabaseRedis
Redis supports caches, sessions, locks, rate limits and temporary state where very low latency matters.
05
ORMPrisma
Prisma provides typed data access for Node.js and TypeScript with migrations, generated clients and explicit transactions.
06
RealtimeSocket.IO
Socket.IO enables realtime interactions for chat, presence, support, notifications and live interfaces.
