The path for programmers to learn SPL


1. Concept and Syntax Learning

Please start with SPL Programming.

Chapters 1-4 introduce basic program logic, which is mainly aimed at beginners without programming experience. Professional programmers can quickly go through it in a few minutes to understand the basic style and syntax of SPL programming. It is important to pay attention to section 4.4 object understanding.

Chapter 5 is also meaningful for experienced programmers. Here is the set operation thinking of SPL, which is very different from other languages. After understanding and mastering it, you can write elegant code. Afterwards, as long as SPL can do the thing, you usually won't be interested in using other languages anymore. Especially in Section 5.7, Lambda syntax is optional for beginners and mandatory for professional programmers.

Chapters 8-11 structured data is the focus, and here we approach structured data operations from a different perspective than SQL, which is equally meaningful for professional programmers. From the perspective of SPL, SQL's understanding of structured data is a bit simple. The world is complex, and the structured data knowledge you have learned from database courses is not broad or deep enough, so you need to relearn!

SPL concepts for beginners and SPL operations for beginners summarize some concepts and operations in SPL programming, and experienced programmers can quickly grasp the characteristics of SPL and its different concepts from SQL.

2. Implement computational logic

To proficiently use SPL for data calculation, you also need to be familiar with relevant functions:

General data table operations in SPL and General operations on cursors in SPL use text files as data sources to illustrate the common SPL functions.

There are more code examples in the operational logic samples.

The code reference lists SPL codes for common operations, including corresponding SPL codes for common SQL statements.

Over a hundred examples are classified and organized in CookBook.

The application computing section will continuously collect online related questions for answers. These can all be used as code references.

3. Integration and Environment

You can find your application environment integration solution in the Invocation & Integration, as well as find the sample code of the data source you need to access in the Data Source.

4. Performance optimization

This is a challenging content.

How to use SPL storage for beginners has summarized the storage mechanism of SPL, and you can have a general idea first and then further understand in practice. This is the foundation of performance optimization. General operations on SPL files use SPL files as data sources, and then introduce the SPL implementation of common operations, which can be used as an exercise.

The high-performance algorithms of SPL are all written in Performance Optimization.

The content of this book is relatively brief. For more detailed information on some algorithms, please refer to Technical Subject, and High-performance Algorithms are some individual performance optimization techniques.

It is particularly recommended to refer to Performance Optimization Exercises using TPCH and SPL Practice Routine to do some exercises, which can be of great help in understanding high-performance algorithms.
