Our composable approach (2024)

FAQs

What is a composable approach? ›

Composable is an approach to the design and delivery. of financial services based on the rapid and flexible. assembly of independent, best-for-purpose systems.

The 4 principles of composable business are modularity, autonomy, discoverability, and reusability.

: capable of being composed. … music expressive of a feeling is clearly composable by one who is not experiencing that feeling and has perhaps never experienced it …

Note: Due to their lifecycle and scoping, you should access and call ViewModel instances at screen-level composables—that is, close to a root composable called from an activity, fragment, or destination of a Navigation graph. You should never pass down ViewModel instances to other composables.

Composable thinking is a critical component of composable enterprise, which involves breaking down complex systems into smaller, reusable components. This approach allows organizations to quickly adapt to changing market conditions and customer needs, and to create new products and services more efficiently.

Typically, with composable solutions, businesses use the power of cloud capabilities to eliminate the need for infrastructure or hardware. Cloud computing is essential because it offers on-demand and flexible access to cloud-based computing resources.

Composable functions can accept parameters, which allow the app logic to describe the UI. In this case, our widget accepts a String so it can greet the user by name. The function displays text in the UI. It does so by calling the Text() composable function, which actually creates the text UI element.

For example, in cloud computing, the concept of "composable infrastructure" allows the creation of virtualized resources (such as computing power, storage, and network) on demand, enabling efficient resource utilization and scalability.

ViewModel is part of the Android Architecture Components that helps manage UI-related data in a lifecycle-conscious way. It survives configuration changes and is ideal for holding and managing UI-related data over a longer lifecycle than traditional Android components like activities or fragments.

Why do we need a ViewModel? ›

The purpose of the ViewModel is to acquire and keep the information that is necessary for an Activity or a Fragment. The Activity or the Fragment should be able to observe changes in the ViewModel. ViewModels usually expose this information via LiveData or Android Data Binding.

It is not necessary for any view to have a view model to function. However, Google recommends the pattern because it leads to good design. If you want to say that your app is MVVM, then you need to keep the view separated from the data that drives it.

Composability refers to the ability for different components or elements to be combined or connected in various ways to create larger, more complex systems or structures. It's a concept often used in the context of software development, computer systems, and engineering, but it applies to other fields as well.

Modularity, autonomy, and interoperability are the three key building blocks of a composable enterprise: Modularity is when data is organized into small, discrete units that can be used to create new data sets quickly and easily.

Gartner coined the term composable business. They defined how moving from traditional to modular architecture makes your business agile and responsive. A composable approach helps you adapt to changing market demands and combine different applications and services.
