Java programming language which was developed with an initiative to write once and run anywhere is virtually the base of every networked application. Java is one of the most popular programming languages today used for developing mobile applications, games, Web-based content and enterprise software.

Webアプリ開発とデータベースマイグレーションには密接な関係があり、Pythonでよく採用されるDjangoやSQLAlchemyには、DBのスキーマを変更するマイグレーション機能があります。一般的に、プログラムを実装するときはリポジトリでブランチを作りそれぞれのブランチで実装作業を進めます。Webアプリの開発でも同様ですが、各ブランチでDBスキーマを変更する場合には注意が必要です。例えば、複数のブランチで同じテーブルのカラムを追加して使いたい場合や、DBスキーマの変更が競合する場合は、ブランチのマージ時に競合してしまいます。多くの機能を並行開発したり、マージするまでの期間が長い場合には、このような競合が増えてしまいます。
このトークでは、Djangoを例に、データベースマイグレーションの仕組みから、実際の開発現場で発生したトラブルとその解決方法について紹介します。
Migration strategies for parallel development of web applications
AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML's syntax to express your application's components clearly and succinctly. AngularJS's data binding and dependency injection eliminate much of the code you would otherwise have to write. And it all happens within the browser, making it an ideal partner with any server technology.
This document discusses WebAssembly and its potential as a game changer for web development. It begins by providing background on how JavaScript evolved and its performance limitations. WebAssembly is presented as a solution to address JavaScript's performance issues by allowing code written in languages like C/C++ to run in the browser at near-native speed. The document explains that WebAssembly is a binary format and build target that works with JavaScript. It discusses how browsers execute WebAssembly, the interaction between WebAssembly and JavaScript, usage scenarios, security considerations, current support and future possibilities like garbage collection and threads. Examples of WebAssembly in use are also provided.

Spring Boot is a framework that makes it easy to create stand-alone, production-grade Spring based Applications that can be "just run". It takes an opinionated view of the Spring platform and third-party libraries so that new and existing Spring developers can quickly get started with minimal configuration. Key features include automatic configuration of Spring, embedded HTTP servers, starters for common dependencies, and monitoring endpoints.
