课程简介

**课程名称:Informatica PowerCenter** **课程概述:** 本课程由Informatica认证顾问讲授,全面深入地讲解了数据仓库(Data Warehousing)的核心概念,包括数据仓库、数据超市(Data Mart)、OLAP与OLTP的区别,以及数据仓库的基本架构和包含暂存区(Staging Area)的架构。 在数据建模方面,课程详细介绍了维度建模(Dimensional Modeling)、星型模型(Star Schema)和雪花模型(Snowflake Schema),并重点讲解了维度(Dimension)、事实(Fact)、缓慢变化维度(Slowly Changing Dimension, Type 1, 2, and 3)、层级(Hierarchy)、无事实表的事实表(Fact less Fact Table)以及总结/聚合表(Summary / Aggregations table)。此外,课程还涵盖了变更数据捕获(Change Data Capture)技术。 **Informatica PowerCenter 组件及概念:** 课程将详细剖析Informatica PowerCenter的核心组件,包括Designer、Repository Manager、Workflow Manager和Workflow Monitor。同时,还将深入讲解Informatica的整体架构、Source Qualifier、Target Designer、Transformations、Mappings、Mapplets、Sessions以及Tasks。 **数据源和目标处理:** 课程指导学员如何处理关系型数据源(Relational Sources)和平面文件数据源(Flat Files),以及如何处理关系型目标(Relational Targets)和平面文件目标(Flat file Targets)。 **Transformations详解:** 课程将详细介绍各类PowerCenter Transformation,包括Expression Transformation、Lookup Transformation、Sequence Generator Transformation、Filter Transformation、Joiner Transformation、Sorter Transformation、Procedural Transformation、Router Transformation、Aggregator Transformation、Update Strategy Transformation、Union Transformation、Rank Transformation、Transaction Control Transformation、Normalizer Transformation、Source Qualifier Transformation、Stored Procedure Transformation以及XML Source Qualifier Transformation。 **PowerCenter 转换语言(Power Center Transformation Language):** 课程还将教授PowerCenter转换语言,涵盖数值函数(Numeric functions)、字符串函数(String Functions)、日期函数(Date Functions)、转换函数(Conversion Functions)、清洗函数(Cleansing Functions)、聚合函数(Aggregate Functions)以及用户定义函数(User Defined Functions)。 **高级Informatica概念:** 本部分将深入探讨高级主题,如Unconnected Lookup Transformation、Unconnected Stored Procedure用于创建和删除索引、Mapplet(包括Mapplet类型和可重用转换的定义)、用户定义函数(User Defined Functions)、Tasks及Tasks类型、Worklet及Worklets类型。此外,还将讨论工作流调度(Scheduling Workflow)、基于约束的加载顺序(Constraint Based Load Ordering)、Target Load Plan、批量处理类型(Types of Batch Processing)、链接条件(Link conditions)、映射参数(Mapping Parameters)、映射变量(Mapping Variables)、会话参数(Session Parameters)、会话恢复(Session Recovery)、普通加载与批量加载的区别(Difference Between Normal and Bulk Loading)、Push Down Optimization、PMCMD Utility、PMREP Utility以及增量聚合(Incremental Aggregation)。 **Lookup Cache 类型:** 课程还将介绍不同类型的Lookup Cache,包括Static Lookup Cache、Dynamic Lookup Cache、Persistence lookup Cache和Shared Lookup Cache。同时,也会讲解Sorter和Rank Cache。 **Task 类型:** 课程将列举并说明各种Session、Command、Email、Timer、Event Wait、Event Raise、Decision、Assignment、Control和Worklet等Task类型。 **ETL 测试:** 课程涵盖ETL测试的各个方面,包括单元测试(UNIT Testing)、系统集成测试(System Integration testing)和性能测试(PERFORMANCE TESTING),以及ETL性能优化技术(ETL Performance Optimization techniques)。
