Mobile OS is big and large and has recently surpassed Windows OS like the world's fastest operating system in the Android mobile OS. As with any mobile computing tool, the mobile OS is growing larger and hardware, and data counting from mobile is increasing too.
Database is the most common way to store and maintain data. For a while now, databases are operated on server side or cloud, and mobile devices can only communicate via network. However, the use of offline usage or low dependence on the network has become popular, relying on applications to be more responsive and network connectivity. Nowadays, apps can locally place DB locally or make a local copy of DB's copy in the cloud and synchronize every day or network connectivity. It helps in faster and responsive applications that are functional even when there is no limited Internet limit.
Databases for mobile should be:
- Storage on mobile devices is low.
- No server required.
- When required or in the form of a library that does not have very limited dependency (embedded)
- Fast and safe.
- Easy to manage by code, and the option to make it private or share it with other apps.
- Low memory and power consumption.
There are many mobile databases coming to market but they do not meet all the requirements listed in this. Let's discuss some of the most popular databases for mobile applications and try to highlight their features, benefits and losses.
- SQLite Affiliate DB is a lightweight version of SQL designed for mobile. It is an in-process library that implements a self-controlled, serverless, zero-configuration, transaction SQL database engine. Unlike any other SQL database, it is an embedded SQL database engine with no server process.
- SQLite supports all relational database features and the open source compact library is supported by two major mobile OS, Android and iOS, and BlackBerry and Windows Phone.
- The SQLite disk is stored in memory as well as memory, and each database file can use a single disk file and cross platform. It is very fast and requires very little memory to operate.
- The kingdom is like traditional databases, querying and filtering, connecting and continuing, but also includes live and fully reactive objects.
- Realm has developed Realm DB and is specially designed to run on mobile devices. Like SQLite, Real is also serverless and cross-platform. It will be stored in Drive as well as in memory.
- The dominant local SQLite above has the following advantages:
- Objects that are in the realm are local goods, you can copy objects, edit them, and save them in the database-you are always working with "live," real object.
- Objects are always synced.
- The kingdom is faster than SQLite. The kingdom can query up to 57 records / second, but can only do SQLite 20 records / sec.
- Data can be secured with transparent encryption and encryption.
- Reyal has reactive architecture, which is directly connected to the UI, when the data is changed it will automatically refresh and appear on the screen.
- It automatically syncs to the Realm object server when there is network connectivity.
- An application may have multiple realms both local and remote
- Different users can set different permissions.
- ORMLite is a lightweight version of Object Relational Mapping. It provides some simple functionality for SQL databases to maintain Java objects. It is ORM Wrapper over any mobile SQL related DB.
- ORMLite is used to simplify complex SQL operations by providing a simple query builder. It also provides powerful abstract database access object (DAO) classes.
- ORMLite can be used in large quantities with critical questions, because "compiled" SQL statements for recursive query functions. It supports configuring tables and fields without annotations, and supports local calls for Android SQLite Database APIs.
- But it does not meet all requirements of ORMLite faster than SQLite and other ORMs in the market, rather than SQLite and Real Estate, compared to SQLite or Real Estate.
- All ORMLite is a good SQLite replacement if the application is large and complex in case of DB usage.
- Berkeley DB is an open source high-performance DB that allows us to maintain data in different ways. It was developed by SleepyCat Software, but was acquired in 2006 by Oracle. It provides API for many languages including Android and iOS.
Berkeley DB can handle data in many ways. It is in relational mode such as SQLite (by replacing SQLite with its own library), or it is similar to key / value pair data bybite arrays and supports multiple data elements for a key. This is also supported as java objects data
- Couchbase Light is powerful NoSQL embedded JSON database. This is the most robust DB with business-level security.
- The data in the Couchbase Light is stored as JSON documents. Each document contains one or more attachments that are stored separately and loaded from the documents.
- Couchbase is a solution provided by Couchbase Light for mobile mobile applications.
- It has three different components: Couchbase Lite, an embedded NoSQL database, Sync Gateway. Couchbase is synchronized with offline first DB and cloud, or when the network is available.
- The Couchbase runs locally on the Lite device and keeps the data in JSON and binary format. All CRUD operations are conducted in local DB. Synchronization code (if needed) is not required by the developer to synchronize with the local DBN cloud, which is managed by the Sync Gateway.
- The Couchbase Lite comes with the controversial resolution mechanism, which is very similar to what Jitt used.
- Another advantage of Couchbase Light is that it provided local APIs for Android and iOS and plugins for Xamarin and PhoneGap.
- So if any NoSQL DB in Mobile OS is needed, the Couchbase Lite is the fastest, most reliable and quantitative size of the bet.
Eventually it depends on application requirements and feasibility to choose which fully fit in DB. But not every mobile DB is to fill most of the above mentioned requirements.For more info visit FuGenX technologies mobile app development
