In the evolving landscape of SAP development, performance is no longer just a nice-to-have--it's a necessity. With the power of SAP HANA and the enhancements introduced in ABAP 7.5, developers are now equipped to rethink how applications are built, executed, and optimized. This book is your guide to that transformation.
We begin by understanding the core shift: moving data-intensive operations directly into the HANA database. When implemented correctly, this "code pushdown" philosophy dramatically reduces data transfer and processing overhead. AMDP (ABAP Managed Database Procedures), our in-database processing engine, enables us to write complex logic directly in SQLScript, harnessing HANA's parallel processing capabilities. We focus on crafting efficient AMDP procedures by adopting set-based operations and minimizing unnecessary data movement.
Next, we explore Core Data Services (CDS) Views, our go-to data modeling tool. CDS Views are not just simple database views; they act as semantic layers that define how our applications interact with data. We learn to create optimized CDS Views by leveraging associations, annotations, and table functions, enabling us to build reusable, high-performance data models. These views simplify complex queries, improve data consistency, and enhance application flexibility.
We then turn to Native SQL, our direct line to the HANA database. While AMDP and CDS Views provide powerful abstractions, Native SQL offers ultimate control for specialized tasks. We embed Native SQL within AMDP procedures to access database-specific features and fine-tune performance for critical operations. Along the way, we apply best practices for writing efficient queries, with a strong focus on indexing, join strategies, and precise data filtering.
Throughout this journey, we emphasize the importance of rigorous testing and proactive monitoring. Just like a race car undergoes extensive testing before hitting the track, our ABAP applications require careful validation to ensure accuracy and optimal performance. We explore techniques for unit testing AMDP procedures, validating CDS Views, and monitoring query performance. We also look at strategies for detecting and addressing potential bottlenecks before they affect end users.
SAP ABAP 7.5 Optimization for HANA is not just about writing faster code--it's about fundamentally rethinking how we develop applications. By embracing code pushdown, leveraging AMDP, CDS Views, and Native SQL, and implementing robust testing and monitoring strategies, we build ABAP applications that are not only faster, but also more scalable, maintainable, and adaptable to the ever-evolving demands of modern business.
You Will:

商品描述(中文翻譯)
在不斷演變的 SAP 開發環境中，性能不再只是可有可無的選項，而是必須具備的條件。隨著 SAP HANA 的強大功能以及 ABAP 7.5 中引入的增強功能，開發人員現在可以重新思考應用程式的建構、執行和優化方式。本書將引導您進行這一轉型。
我們首先了解核心轉變：將數據密集型操作直接移入 HANA 數據庫。當正確實施時，這種「代碼下推」的理念能顯著減少數據傳輸和處理的開銷。AMDP（ABAP 管理的數據庫程序），我們的內數據庫處理引擎，使我們能夠直接在 SQLScript 中編寫複雜邏輯，充分利用 HANA 的並行處理能力。我們專注於通過採用基於集合的操作來製作高效的 AMDP 程序，並最小化不必要的數據移動。
接下來，我們探索核心數據服務（CDS）視圖，這是我們的主要數據建模工具。CDS 視圖不僅僅是簡單的數據庫視圖；它們作為語義層，定義我們的應用程式如何與數據互動。我們學習如何通過利用關聯、註釋和表函數來創建優化的 CDS 視圖，使我們能夠構建可重用的高性能數據模型。這些視圖簡化了複雜查詢，提高了數據一致性，並增強了應用程式的靈活性。
然後，我們轉向原生 SQL，這是我們與 HANA 數據庫的直接連接。雖然 AMDP 和 CDS 視圖提供了強大的抽象，但原生 SQL 為專門任務提供了最終控制。我們在 AMDP 程序中嵌入原生 SQL，以訪問數據庫特定功能並微調關鍵操作的性能。在此過程中，我們應用編寫高效查詢的最佳實踐，重點關注索引、聯接策略和精確的數據過濾。
在這段旅程中，我們強調嚴格測試和主動監控的重要性。就像賽車在上賽道之前需要經過廣泛測試一樣，我們的 ABAP 應用程式也需要仔細驗證，以確保準確性和最佳性能。我們探索 AMDP 程序的單元測試技術、驗證 CDS 視圖和監控查詢性能的方法。我們還研究在潛在瓶頸影響最終用戶之前檢測和解決問題的策略。
《SAP ABAP 7.5 優化 HANA》不僅僅是關於編寫更快的代碼，而是關於根本性地重新思考我們如何開發應用程式。通過擁抱代碼下推、利用 AMDP、CDS 視圖和原生 SQL，並實施穩健的測試和監控策略，我們構建的 ABAP 應用程式不僅更快，還更具可擴展性、可維護性，並能適應現代商業不斷演變的需求。
您將：
- 學習如何實施「代碼下推」理念，將數據密集型操作直接移入 HANA 數據庫，以減少數據傳輸和處理開銷。
- 理解如何創建優化的 CDS 視圖，利用關聯、註釋和表函數來構建可重用的高性能數據模型，簡化複雜查詢並提高數據一致性。
- 探索如何使用 AMDP 直接在 SQLScript 中編寫複雜邏輯，充分利用 HANA 的並行處理能力，並使用原生 SQL 進行專門任務，訪問數據庫特定功能以優化性能。
