+# Storage
+
+The RADFish storage system provides a robust and flexible solution for managing data in your applications. It's designed to work seamlessly with offline-first applications, providing a consistent API for storing and retrieving data from device storage.
+
+## Overview
+
+The storage system is built around several key components that work together:
+
+1. **Connector** - Connects to a specific storage backend (e.g., IndexedDB).
+2. **Schema** - Defines the structure and validation rules for your data.
+3. **Store** - Manages collections and provides access to data.
+4. **Collection** - Handles CRUD operations for a specific type of data.
+
+## Setting Up Storage in an Application
+
+The most common way to set up storage in a RADFish application is through the `Application` constructor. This approach automatically handles connecting to the storage backend and setting up collections.
+
+```jsx
+import { Application } from "@nmfs-radfish/radfish";
+import { IndexedDBConnector } from "@nmfs-radfish/radfish/storage";
+
+const app = new Application({
+  stores: {
+    weatherSurvey: {
+      connector: new IndexedDBConnector("weather-survey-app"),
+      collections: {
+        Form: {
+          schema: {
+            fields: {
+              id: {
+                type: "string",
+                primaryKey: true,
+              },
+              surveyDate: {
+                type: "string",
+                required: true,
+              },
+              submittedBy: {
+                type: "string",
+                required: true,
+              },
+              submittedAt: {
+                type: "timestamp",
+              },
+              status: {
+                type: "string",
+                required: true,
+              },
+            },
+          },
+        },
+      },
+    },
+  }
+});
+```
+
+## Key Components
+
+### Connector
+
+A Connector is responsible for connecting to a specific storage backend and providing an interface for collections to interact with that backend.
+
+RADFish provides two built-in connectors:
+
+1. **IndexedDBConnector** - Uses IndexedDB for storage (recommended for most applications)
+2. **LocalStorageConnector** - Uses localStorage for storage (limited capacity, but simpler)
+
+```jsx
+import { IndexedDBConnector } from "@nmfs-radfish/radfish/storage";
+
+const connector = new IndexedDBConnector("weather-survey-app");
+```
+
+### Schema
+
+A Schema defines the structure and validation rules for a collection of data. It defines all the fields, their types, and constraints for a particular type of data.
+
+```jsx
+const formSchema = {
+  fields: {
+    id: {
+      type: "string",
+      primaryKey: true,
+    },
+    surveyDate: {
+      type: "string",
+      required: true,
+    },
+    submittedBy: {
+      type: "string",
+      required: true,
+    },
+    submittedAt: {
+      type: "timestamp",
+    },
+    // ... other fields
+  },
+};
+```
+
+#### Schema Field Properties
+
+| Property     | Type    | Description                                               |
+| ------------ | ------- | --------------------------------------------------------- |
+| `type`       | string  | The data type of the field (see supported types below)    |
+| `required`   | boolean | Indicates if the field is required                        |
+| `primaryKey` | boolean | Marks the field as the primary key for the collection     |
+| `default`    | any     | Default value for the field if not provided               |
+| `minLength`  | number  | Minimum length for string fields                          |
+| `minimum`    | number  | Minimum value for number fields                           |
+| `maximum`    | number  | Maximum value for number fields                           |
+| `pattern`    | RegExp  | Regular expression pattern for string validation          |
+| `unique`     | boolean | Indicates if the field value must be unique in collection |
+
+#### Supported Data Types
+
+The Schema system supports the following data types:
+
+| Type             | Description                           | Valid Values                                             |
+| ---------------- | ------------------------------------- | -------------------------------------------------------- |
+| `string`         | Text values                           | Any string                                               |
+| `number`         | Numeric values (integers or decimals) | Any number                                               |
+| `boolean`        | Boolean values                        | `true` or `false`                                        |
+| `timestamp`      | Date and time values with timezone    | Date object or ISO string (e.g., `2025-05-16T14:23:00Z`) |
+| `date`           | Date values (without time)            | Date object or ISO date string (e.g., `2025-05-16`)      |
+| `time`           | Time values (without date)            | String in 24-hour format (e.g., `14:23:00`)              |
+| `datetime-local` | Date and time values without timezone | Date object or ISO string (e.g., `2025-05-16T14:23:00`)  |
+
+#### Schema Validation
+
+The Schema class provides a `validate` method to validate data against the schema rules. It can be used to check if data is valid before attempting to save it to a collection.
+
+```jsx
+// Get a collection's schema
+const schema = formCollection.schema;
+
+// Data to validate
+const data = {
+  surveyDate: "2025-05-16",
+  submittedBy: "John Smith",
+  status: "draft",
+};
+
+// Validate data (non-strict mode)
+const validation = schema.validate(data);
+
+if (!validation.isValid) {
+  console.error("Validation errors:", validation.errors);
+  // Example output: [{field: "id", error: "Field is required"}]
+} else {
+  // Data is valid
+  await formCollection.create(data);
+}
+```
+
+The `validate` method returns an object with two properties:
+- `isValid` (boolean): Indicates if the data is valid
+- `errors` (array): List of validation error objects if any
+
+Each error object in the errors array has the following format:
+- `field` (string): The name of the field that failed validation
+- `error` (string): A description of the validation error
+
+##### Strict Mode Validation
+
+You can also use strict mode, which throws a ValidationError instead of returning an error object:
+
+```jsx
+try {
+  // Passing 'true' as the second parameter enables strict mode
+  schema.validate(data, true);
+
+  // If validation passes, create the record
+  await formCollection.create(data);
+} catch (error) {
+  if (error.name === "ValidationError") {
+    console.error("Validation errors:", error.errors);
+    // Handle validation errors
+  } else {
+    // Handle other errors
+    console.error("Error:", error.message);
+  }
+}
+```
+
+### Store
+
+A Store manages collections for a specific domain of your application. Each store has a connector and can have multiple collections.
+
+```jsx
+import { Store } from "@nmfs-radfish/radfish/storage";
+
+const store = new Store({
+  name: "weatherSurvey",
+  connector: connector
+});
+```
+
+### Collection
+
+A Collection provides methods for creating, reading, updating, and deleting data for a specific schema. Collections validate data against their schema before performing any operations.
+
+```jsx
+// Get a collection from the Application
+const formCollection = app.stores.weatherSurvey.getCollection("Form");
+
+// Create a new form
+const newForm = await formCollection.create({
+  surveyDate: "2025-05-16",
+  submittedBy: "John Smith",
+  status: "draft"
+});
+
+// Find forms
+const draftForms = await formCollection.find({ status: "draft" });
+
+// Update a form
+const updatedForm = await formCollection.update({
+  id: newForm.id,
+  status: "submitted",
+  submittedAt: new Date().toISOString()
+});
+
+// Delete a form
+await formCollection.delete({ id: newForm.id });
+```
+
+## Working with Collections
+
+### Creating Records
+
+To create a new record, call the `create` method on a collection:
+
+```jsx
+const newForm = await formCollection.create({
+  surveyDate: "2025-05-16",
+  submittedBy: "John Smith",
+  status: "draft"
+});
+
+console.log("Created form with ID:", newForm.id);
+```
+
+### Finding Records
+
+To retrieve records from a collection, use the `find` method:
+
+```jsx
+// Find all draft forms
+const draftForms = await formCollection.find({ status: "draft" });
+
+// Find a specific form by ID
+const form = await formCollection.find({ id: "form-123" });
+```
+
+### Updating Records
+
+To update a record, use the `update` method:
+
+```jsx
+const updatedForm = await formCollection.update({
+  id: "form-123",
+  status: "submitted",
+  submittedAt: new Date().toISOString()
+});
+```
+
+### Deleting Records
+
+To delete records, use the `delete` method:
+
+```jsx
+// Delete a specific form
+await formCollection.delete({ id: "form-123" });
+
+// Delete all draft forms
+await formCollection.delete({ status: "draft" });
+```
+
+## Event Handling
+
+The storage system emits events during various operations, allowing you to hook into the lifecycle of data operations.
+
+```jsx
+// Listen for events at the collection level
+formCollection.addEventListener('beforeCreate', (event) => {
+  // Add defaults if needed
+  if (!event.detail.data.status) {
+    event.detail.data.status = "draft";
+  }
+
+  console.log('About to create form:', event.detail.data);
+});
+
+formCollection.addEventListener('create', (event) => {
+  console.log('Form created:', event.detail.data);
+});
+
+// Listen for events at the connector level (across all collections)
+connector.addEventListener('create', (event) => {
+  console.log(`Created record in ${event.detail.schema.name}:`, event.detail.data);
+});
+```
+
+## Best Practices
+
+1. **Define Clear Schemas**: Well-defined schemas ensure data integrity and make your application more maintainable.
+
+2. **Use IndexedDB for Larger Applications**: IndexedDB provides more storage space and better performance than LocalStorage.
+
+3. **Handle Offline Scenarios**: Implement sync strategies to handle data that needs to be synchronized with a server when connectivity is restored.
+
+4. **Use Events for Side Effects**: Use event listeners for logging, caching, and other side effects in response to changes to your data.
+
+5. **Validate User Input**: While collections validate data against schemas, it's still good practice to validate user input before calling collection methods.
+
+## Example: Complete Weather Survey Application
+
+Here's an example of how to set up a complete weather survey application with forms:
+
+```jsx
+import { Application } from "@nmfs-radfish/radfish";
+import { IndexedDBConnector } from "@nmfs-radfish/radfish/storage";
+
+// Initialize the application with storage
+const app = new Application({
+  stores: {
+    weatherSurvey: {
+      connector: new IndexedDBConnector("weather-survey-app"),
+      collections: {
+        Form: {
+          schema: {
+            fields: {
+              id: {
+                type: "string",
+                primaryKey: true,
+              },
+              surveyDate: {
+                type: "string",
+                required: true,
+              },
+              submittedBy: {
+                type: "string",
+                required: true,
+              },
+              submittedAt: {
+                type: "timestamp",
+              },
+              status: {
+                type: "string",
+                required: true,
+              },
+            },
+          },
+        },
+      },
+    },
+  }
+});
+
+// When the application is ready
+app.on("ready", async () => {
+  // Get collections
+  const formCollection = app.stores.weatherSurvey.getCollection("Form");
+
+  // Create a new form
+  const newForm = await formCollection.create({
+    surveyDate: "2025-05-16",
+    submittedBy: "John Smith",
+    status: "draft"
+  });
+
+  // Mark the form as submitted
+  await formCollection.update({
+    id: newForm.id,
+    status: "submitted",
+    submittedAt: new Date().toISOString()
+  });
+});
+```
+
+By following these patterns, you can create powerful applications that work seamlessly online and offline, providing a consistent user experience regardless of network conditions.
