About IBM Big Data Engineer
This certification is intended for IBM Big Data Engineers. The Big Data Engineer works directly with the Data Architect and hands-on Developers to convert the architect’s Big Data vision and blueprint into a Big Data reality. The Data Engineer possesses a deep level of technical knowledge and experience across a wide array of products and technologies.

Course Outline
1. Data Loading
• Load unstructured data into InfoSphere BigInsights
• Import streaming data into Hadoop using InfoSphere Streams
• Create a BigSheets workbook
• Import data into Hadoop and create Big SQL table definitions
• Import data to HBase
• Import data to Hive
• Use Data Click to load from relational sources into InfoSphere BigInsights with a self-service process
• Extract data from a relational source using Sqoop
• Load log data into Hadoop using Flume
• Insert data via IBM General Parallel File System (GPFS) Posix file system API
• Load data with Hadoop command line utility
2. Data Security
• Keep data secure within PCI standards
• Uses masking (e.g. Optim, Big SQL), and redaction to protect sensitive data
3. Architecture and Integration
• Implement MapReduce
• Evaluate use cases for selecting Hive, Big SQL, or HBase
• Create and/or query a Solr index
• Evaluate use cases for selecting potential file formats (e.g. JSON, CSV, Parquet, Sequence, etc..)
• Utilize Apache Hue for search visualization
4. Performance and Scalability
• Use Resilient Distributed Dataset (RDD) to improve MapReduce performance
• Choose file formats to optimize performance of Big SQL, JAQL, etc.
• Make specific performance tuning decisions for Hive and HBase
• Analyze performance considerations when using Apache Spark
5. Data Preparation, Transformation, and Export
• Use Jaql query methods to transform data in InfoSphere BigInsights
• Capture and prep social data for analytics
• Integrating SPSS model scoring in InfoSphere Streams
• Implement entity resolution within a Big Data platform (e.g. Big Match)
• Utilize Pig for data transformation and data manipulation
• Use Big SQL to transform data in InfoSphere BigInsights
• Export processing results out of Hadoop (e.g. DataClick, DataStage, etc.)
• Utilize consistent regions in InfoSphere Streams to ensure at least once processing
