 summary: Add structured data storage to your Taubyte applications with key-value databases. Like storage, databases are created on-the-fly when first used—enabling dynamic, multi-tenant data isolation without extra configuration.

-## Advanced: Per-User Databases
-
-Here's how to implement isolated databases per user:
-
-### Database Configuration
-
-Create a database with a regex matcher:
-```
-user/data/.*
-```
-
-### User-Scoped Functions
-
-```go
-package lib
-
-import (
-    "encoding/json"
-    "github.com/taubyte/go-sdk/database"
-    "github.com/taubyte/go-sdk/event"
-)
-
-type UserDataRequest struct {
-    UserID string `json:"user_id"`
-    Key    string `json:"key"`
-    Value  string `json:"value"`
-}
-
-//export userSet
-func userSet(e event.Event) uint32 {
-    h, err := e.HTTP()
-    if err != nil {
-        return 1
-    }
-
-    body := h.Body()
-    defer body.Close()
-    
-    var req UserDataRequest
-    if err := json.NewDecoder(body).Decode(&req); err != nil {
-        h.Write([]byte(`{"error": "invalid request"}`))
-        return 1
-    }
-
-    // Dynamic database path per user
-    dbPath := "user/data/" + req.UserID
-    
-    db, err := database.Open(dbPath)
-    if err != nil {
-        h.Write([]byte(`{"error": "failed to open database"}`))
-        return 1
-    }
-    defer db.Close()
-
-    db.Put(req.Key, []byte(req.Value))
-    h.Write([]byte(`{"status": "stored for user ` + req.UserID + `"}`))
-    return 0
-}
-```
-
-This creates **isolated databases per user**:
-- `user/data/alice` → Alice's database (created on first use)
-- `user/data/bob` → Bob's database (created on first use)
