#2.1 Mengenal jenis-jenis integrasi aplikasi dalam sudut pandang metode yang digunakan

Summary

This video explores the different levels of integration within enterprise applications. It covers integration at four key levels: data level (database), application level (APIs), method level (business processes), and user interface level. The speaker elaborates on each type, including their advantages and drawbacks. The most common and ideal integration method is through APIs, as it offers security, flexibility, and selectivity, allowing data to be accessed or modified only as needed. The video also touches on the importance of developers creating APIs to ensure seamless system integration across various platforms, including web and mobile versions.

Takeaways

• 😀 The video covers various levels of enterprise application integration (EAI), focusing on integration methods and architectures.
• 😀 EAI can be approached in different levels: data level, application level, method level, and user interface level.
• 😀 At the data level, integration involves connecting databases and synchronizing data, such as moving data from one system's database to another's.
• 😀 One approach to data level integration involves manual or semi-manual methods, where data is transferred or copied at regular intervals.
• 😀 A major downside of data level integration is the risk of exposing sensitive database information to external vendors.
• 😀 At the application level, integration is facilitated by APIs (Application Programming Interfaces), allowing applications to interact without directly accessing databases.
• 😀 The use of APIs helps secure data exchange, making it more selective and manageable, but both sides need to set up their APIs for successful integration.
• 😀 The method level integration refers to business process integration, where various application methods are triggered and coordinated to achieve specific tasks.
• 😀 At the user interface level, integration occurs when direct database access or API calls are not possible, often by scraping or extracting data visible in the interface.
• 😀 The most commonly used and ideal form of integration is through APIs, ensuring secure, selective, and manageable data exchange between systems.
• 😀 Developers are increasingly focusing on creating APIs for future integration needs, ensuring that their applications can adapt and expand smoothly over time.

Q & A

What are the two main aspects in which enterprise application integration can be viewed?

Enterprise application integration can be viewed in two main aspects: its methods and its architecture.

What are the four integration levels mentioned in the video?

The four integration levels discussed are data level (or database level), application level, method level, and user interface level.

How does integration at the data level work?

At the data level, integration involves directly connecting databases to exchange data. For instance, data from an Oracle database can be transferred to a MySQL database, either manually or using semi-automated processes, such as scheduled jobs.

What are the advantages and disadvantages of integrating at the data level?

The advantage of integrating at the data level is its simplicity and direct approach. However, the disadvantages include potential security risks due to direct database access and the possibility of human error if the process is manual.

What is the role of APIs in application-level integration?

At the application level, APIs (Application Programming Interfaces) act as intermediaries between applications. They allow applications to exchange data without direct access to each other's databases, ensuring security and flexibility in data retrieval.

What are the benefits and challenges of using APIs for integration?

APIs provide more security compared to direct database access and allow selective data retrieval. However, both parties need to develop and maintain APIs, which can be a challenge, especially if one side is unwilling to cooperate.

How does integration at the method or business process level work?

At the method level, integration involves calling specific business processes or methods within an application. These methods can be accessed remotely by another application, enabling the execution of tasks without direct interaction with the application's data.

What is the primary use case for integrating at the user interface level?

Integration at the user interface level is used when direct access to data or APIs is not possible, and the only available option is to extract visible data from the user interface of an application or website.

What are the risks and limitations of user interface-level integration?

The main limitation of user interface-level integration is that it may not provide complete or accurate data, as only what is displayed on the interface is accessible. This data might also be incomplete or outdated, and extracting it could be unreliable.

Why is integration using APIs considered the most ideal method in modern systems?

Integration using APIs is considered the most ideal method because it provides secure, selective, and efficient data access between applications. It is also widely adopted and supports scalability, allowing future upgrades or changes in systems without disrupting the integration.
