Download for Mac. Download for Linux. Download for Windows. Opening a Realm is simply performed by calling the static open method on the Realm class. Pass a configuration object. For full details about the configuration object, see the API Reference for configuration. Some of the more common keys for the object, beyond schemainclude:.

You may have noticed in all previous examples that the path argument has been omitted. In this case the default Realm path is used. You can access and change the default Realm path using the Realm.

All sync related documentation has been moved to our platform documentation. For example, you may want to bundle some data with your application in a Realm file, in addition to your main Realm.

You can do this by specifying the path argument when initializing your realm. All paths are relative to the writable documents directory for your application:. Another option available when opening a Realm is the schemaVersion property. When omitted, the schemaVersion property defaults to 0. You are required to specify the schemaVersion when initializing an existing Realm with a schema that contains objects that differ from their previous specification.

If the schema was updated and the schemaVersion was not, an exception will be thrown. If you wish to retrieve the current schema version of a Realm, you may do so with the Realm.

You can create a realm instance by simply invoking the constructor and passing a configuration object to it. Realm data models are defined by the schema information passed into a Realm during initialization. To avoid size limitations and a performance impact, it is best not to store large blobs such as image and video files directly in Realm.A Realm is an instance of a Realm Mobile Database container. Realms can be local, synchronized, or in-memory.

In practice, your application works with any kind of Realm the same way. In-memory Realms have no persistence mechanism, and are meant for temporary storage. A synchronized Realm uses the Realm Object Server to transparently synchronize its contents with other devices. Or, it could be a shopping cart, accessible only to devices owned by you. Realms are lightweight, and your application can be using several at one time.

On mobile platforms, there are some resource constraints, but up to a dozen open at once should be no issue. The concepts being discussed are cross-platform; simple examples will be given in Swift.

Consult the documentation section for your preferred binding for examples in your language. In JavaScript, the schema for your model must be passed into the constructor as part of the configuration object. See Models in the JavaScript documentation for details. When you open a Realm, you pass the constructor a configuration object that defines how to access it. The configuration object specifies where the Realm database is located:. The configuration object may specify other values, depending on your language, and is usually used for migrations when those are necessary.

As noted above, the configuration object also includes the model schema in JavaScript. Opening a synchronized Realm, therefore, might look like this. Synchronized Realms may be public, private, or shared. The difference between them is access controlswhich users can read and write to them. The URL format may also look a little different:.The Realm Platform is a next-generation data layer for cross-platform applications.

Realm is reactive, concurrent, and lightweight, allowing you to work with live, native objects. Use Realm to enable your apps to work seamlessly in weak signal, offline or outage scenarios. That version also supports the new MongoDB Realm platform with many more features.

A good place to initialize Realm is in onCreate on an application subclass:. A Realm is an instance of a Realm Mobile Database container.

Realms can be local or synchronized. A synchronized Realm uses the Realm Object Server to transparently synchronize its contents with other devices.

In practice, your application works with any Realm, local or synchronized, the same way. Open a Realm by instantiating a new Realm object.

To control how Realms are created, use a RealmConfiguration object. The minimal configuration usable by Realm is:. That configuration—with no options—uses the Realm file default. To use another configuration, you would create a new RealmConfiguration object:. You can have multiple RealmConfiguration objects, so you can control the version, schema and location of each Realm independently. Get the absolute path of a Realm by using Realm.A realm is a functional grouping of database schemas and roles that must be secured for a given application.

Think of a realm as zone of protection for your database objects. A schema is a logical collection of database objects such as tables, views, and packages, and a role is a collection of privileges.

By classifying schemas and roles into functional groups, you can control the ability to use system privileges against these groups and prevent unauthorized data access by the DBA or other powerful users with system privileges.

Oracle Database Vault does not replace the discretionary access control model in the existing Oracle database. It functions as a layer on top of this model for both realms and command rules. After you create a realm, you can register a set of schema objects or roles secured objects for realm protection and authorize a set of users or roles to access the secured objects.

For example, after you install Oracle Database Vault, you can create a realm to protect all existing database schemas that are used in an accounting department. The realm prohibits any user who is not authorized to the realm to use system privileges to access the secured accounting data. You can run reports on realms that you create in Oracle Database Vault.

This chapter explains how to configure realms by using Oracle Database Vault Administrator. Database Vault Account Management: Defines the realm for the administrators who manage and create database accounts and database profiles. This realm also controls the ability to grant system privileges and database administrator roles. In general, to enable realm protection, you first create the realm itself, and then you edit the realm to include realm secured objects, roles, and authorizations.

Name: Enter a name for the realm. It can contain up to 90 characters in mixed-case. This attribute is mandatory. Description: Enter a brief description of the realm. The description can contain up to characters in mixed-case. This attribute is optional. You may want to include a description the business objective of the given application protection and document all other security policies that compliment the realm's protection. Also document who is authorized to the realm, for what purpose, and any possible emergency authorizations.

Status: Select either Enabled or Disabled to enable or disable the realm. A realm is enabled by default. Audit On Failure: Default. Creates an audit record when a realm violation occurs for example, when an unauthorized user tries to modify an object that is protected by the realm. Audit On Success or Failure: Creates an audit record for any activity that occurs in the realm, including both authorized and unauthorized activities.

After you create a new realm, you are ready to add schema and database objects to the realm for realm protection, and to authorize users and roles to access the realm. To do so, you edit the new realm and then add its objects and its authorized users.

Realm-secured objects define the territory that a realm protects. The realm territory is a set of schema and database objects and roles.
