Diving into mobile app development? Enhance your app’s capacity effortlessly by integrating it with a cloud database. In our new video guide, we take you through an easy-to-follow guide on setting this up using Appery.io, making your app more dynamic and robust.

Why Cloud Databases?

Cloud databases provide a scalable, secure, and efficient way to manage app data. Whether it’s Amazon RDS, SQL Server, or PostgreSQL, these platforms help you handle large volumes of data without compromising on performance. The best part? Appery.io supports various databases, opening a realm of possibilities for your applications.

Getting Started with Database Connection

First, log into the Appery.io App Builder. Go to the API Express tab and create a new database connection. This process is user-friendly and supports different database types. For instance, connecting to a PostgreSQL database is as straightforward as inputting credentials and testing the connection for viability.

Exposing Database Data via REST Service

Once your database is connected, the next step is to expose your data. This involves creating an API Express project that allows your app to communicate with the database via RESTful services. You’ll find this feature particularly useful as it forms the backbone for data interaction within your app.

Building and Testing Your Mobile App

The final step is the most exciting—building your mobile app. Appery.io simplifies this with features that accommodate both no-code and low-code development approaches. Start by creating a new app and dragging the necessary components like Lists or Buttons onto your app’s screens. Then, integrate the services you’ve created to fetch or input data into your cloud database.

Real-World Application: Dynamic Data Handling

To illustrate, imagine your app displays a list of data entries from a cloud PostgreSQL database. You can enhance this by adding functionalities like creating new data entries through the app. This not only makes your app interactive but also practical for real-world use. Testing these functions within Appery.io is straightforward and gives you a firsthand look at your app’s performance.

Conclusion: Embrace the Power of Integration

By integrating cloud databases into your mobile apps, you unlock new layers of functionality and efficiency. As demonstrated in our video guide, the process can be surprisingly simple yet incredibly impactful. Whether you want to improve an existing app or start a new project, cloud database integration is a gateway to more sophisticated and responsive app solutions.

While Bitcoin cryptocurrency is revolutionizing online payments, Ethereum is now ready to revolutionize any industry that deals with data or transactions of any kind:

• Banking and payments
• Cybersecurity
• Supply chain management
• Networking and IoT
• Forecasting
• Insurance
• Private transport & ride sharing
• Online data storage
• Charity
• Voting
• Government
• Public benefits
• Healthcare
• Energy management
• Online music
• Retail
• Real estate
• Crowdfunding

All the blockchain-based systems such as Bitcoin or Ethereum are software. In order to start using Ethereum, a wallet along with an associated address is required. Once this is in place, a dispatched transaction can be broadcast to the network, where “miners” verify it and add it to the transaction history.

Using Appery.io with Ethereum

Naturally, it’s quite easy to use Appery.io to build a hybrid app hooked up with Ethereum. It just takes a few simple steps to build the wallet and ready the Ethereum setup.

First things first. In order to do anything on an Ethereum network you need to create an account. There are various ways to go about this, but the simplest one, suggested by Ethereum developers, is through the command line tool. Once this is done, a public key and a private key are issued. The public key is your unique address on the network.

After that, if you want to go with your own cryptocurrency, you need to build a smart contract using the command line. This produces a unique smart contract address. Also, make sure that you manifest enough of your own coins on your smart contract.

Next, the easiest way to develop the wallet app is to leverage the Appery.io API Express Ethereum component. With Appery.io, a citizen developer can concentrate on innovation not infrastructure to build the wallet app. The wallet is a two-page app. The first page shows the current balance in various cryptocurrencies as well as a list of transactions. The second page executes transactions. In addition, a sign-in page can be introduced to address security issues. Under the hood, the Appery.io API Express Ethereum services (built into the component) consume the aforementioned account and contract addresses to do the job.

Then, you need to top up your account to start testing the wallet app. In order to obtain free test Ethers, please go to faucet.rinkeby.io.

Finally, start the wallet app. Voilà! Now you are ready to send and receive cryptocoins.

According to numerous scientific studies, a comfortable work environment directly contributes to the bottom line. Hear what these experts say:

“With high air quality, an individual productivity improvement can range from 13.5% up to 87%.”

— Prof. Vivian Loftness, Carnegie Mellon University

“The incidence of absenteeism or respiratory infections was found to be lower among people working in high air quality environments.”

— Prof. Anthony V. Arundel, University of Tasmania

With that in mind, we decided to improve its controllable indoor air quality. To accomplish this goal, an Appery.io-powered solution has been built to control temperature and humidity in its office spaces in the face of the most demanding conditions.

The solution’s design is based on a hub to aggregate probes, a database, and a mobile app. Appery.io API Express (built into the Appery.io platform) was used to expose both the Raspberry Pi sensors and the Appery.io cloud database as REST services, making the orchestration process smooth and fast.

In addition, each conference facility is managed by a booking app to ensure higher utilization. As a result of its initial success, that booking app was extended to provide an interface for controlling indoor air quality.

The really amazing thing was that the complete solution was designed, developed, and tested in about 16 hours.

Today we are introducing a new way for enterprise customers to get the benefits of using our API Express backend services.

API Express allows enterprises to quickly “mobilize” existing systems by making it easier to add RESTful APIs so that theses systems can easily be accessed from other applications including mobile or desktop apps. This enables the modernization of legacy systems without re-writing them. This is highly beneficial as many enterprises are still constrained by legacy applications that are not mobile friendly.

With API Express Standalone, enterprises are now free to deploy this service behind their own firewall, while still taking advantage of the rest of the Appery.io platform in the cloud. Enterprise customers will now be able to install API Express on demand using a Docker container. For more details about the configuration process and about installing see our documentation.

Appery.io API Express make it fast and simple to connect to an enterprise data source and expose it via a REST API. With API Express you can quickly create an API for:

• A relational database
• A WSDL service (SOAP)
• An existing REST API

In this tutorial, I’m going to show how to expose an existing WSDL service as a REST API and then build a mobile app using the API.
