The Template Method pattern defines the skeleton of an algorithm in an abstract class, leaving some steps to be implemented by subclasses. This allows subclasses to redefine certain steps of the algorithm without changing its structure. The algorithm is encapsulated in a single class, with subclasses only needing to provide specialized implementation details for certain steps. The abstract class declares primitive methods that subclasses must implement, as well as concrete methods and hooks to allow subclasses to optionally modify the algorithm's behavior.
The Template Method pattern defines the skeleton of an algorithm in an abstract class but allows subclasses to override specific steps of the algorithm without changing its structure. The abstract class implements a template method that defines the order of operations, calling both operations in the abstract class and abstract primitive operations implemented by subclasses. Subclasses implement the primitive operations to carry out subclass-specific steps but cannot override the template method if it should not be overridden. The pattern establishes an "inverted control structure" where the parent class calls operations of the subclass rather than the other way around.
FinTech Forum turned two years old in July 2015, and true to our tradition we decided to celebrate with the growing community of startups who have presented at our events.
Last year this article was sufficient: http://www.fintechforum.de/fintech-forum-d-a-ch-turns-one/
This year, we had to reach out to nearly 100 startups who have presented so far at our five events. We asked them (like last year), what they have been up to (achievements) and how could we help them (wants).
The number of responses we got needed a yearbook – so here it is!
As before, if you are interested in talking to any of the startups, please feel free to reach out to the founders directly via LinkedIn or Xing, or drop us a line and we will be more than happy to make an introduction.

Design Pattern is …
? Why
– 重用公認優良設計,避免解決問題時重蹈覆轍
– 建立通用術語,分析設計時能有對問題的共識
– 幫我們分析,了解問題,避免過早處理細節
? What
– 在一個特定情境(context)中,針對重複出現問題所提出有效地解決方法
? When
– 套用時機
? 設計階段
– 了解客戶需求,完成分析工作(建立use case mode與domain model)後建立design model 時
? 實作階段
– 當設計階段套用design pattern的「作用力(force)」還不是很具體,只能先利用基本的物件導向
設計方法來設計物件與分配責任
– 在實作幾個功能(use case或user story)之後才慢慢發現可以藉由重構(refactoring)方法來套用
design pattern
? 設計時套用可能因為問題尚不清楚而過度設計,實作時重構比較保險 - Erich Gamma
– 選擇套用Scrum,一部分一部分重構
