Data comes in many shapes and sizes, and every company struggles to find ways to transform, validate, and enrich data for multiple purposes. The problem has been around as long as data, and the market has an overwhelming number of options. In this presentation we look at the problem and key options from vendors in the market today. Dremio is a new approach that eliminates the need for stand alone data prep tools.

- 10. Data Prep
- 13. Old v. new approaches
- 14. Data Integration v. Data Prep Data Integration Data Prep Primary user IT Business Analyst User works from Metadata Data samples Prioritizes Governance, security Ease of use, time to insight Sample vendors Informatica, IBM, SAS, SQL tools Alteryx, Trifacta, Paxata
- 15. Data Integration is the standard • For 25+ years, Data Integration has been an essential tool for IT • Pros • Mature, robust • Deep integrations to enterprise standards • Security and governance controls • Server-based: scalable, centralized • Cons • IT users only • Assumes minimal data quality • Mature for enterprise sources • Less mature for cloud, 3rd party apps, Hadoop, NoSQL • Complex, expensive
- 16. Data Prep prioritizes speed, ease of use • Newer entrants, architected for modern resources • Pros • User experience works for both IT, Business • Data-centric model vs. metadata-centric model • Support for Hadoop, NoSQL, Cloud, machine learning • Can leverage Hadoop and/or cloud for processing, storage • Faster time to value • Cons • Less mature tech stack • Small vendors, limited ecosystem of integrations and skills • Security integrations less comprehensive • Assumes governance, authority, lineage handled elsewhere • Still need IT on board and coordinating process

- 18. Open source alternatives • RDBMS • Pros: SQL based; mature; ecosystem • Cons: non-relational sources; scalability; ease of use • Apache Hive • Pros: scalabilty; SQL based; Hadoop integrations; • Cons: latency; ease of use; integrations • Apache Spark • Pros: scalability; performance; Python/R integration; ML • Cons: ease of use; integrations; maturity • Python Pandas • Pros: performance; pervasive skills; ecosystem; flexibility • Cons: scale out is complex; ease of use • R dplyr • Pros: performance; pervasive skills; ecosystem; flexibility • Cons: scale out is complex; ease of use
- 28. How to decide?
- 29. Category Good Fit Primary User Model Scalability ETL Tools Static, predictable integrations between enterprise tech IT Data Pipeline, metadata-based Single server BI Tools ”Last Mile” data prep Business Embedded Desktop Trifacta, Paxata Scalable, collaborative data prep for business users Business Spreadsheet, sample-based Hadoop cluster Custom Scripts Maximum flexibility IT Data Pipeline, metadata-based Single server Alteryx, Datawatch Building BI extracts, easier to use than ETL IT Data Pipeline, metadata-based Desktop (single server optional) SAS Data Loader IT users IT Data Pipeline, metadata-based Single server Tamr Human-aided ML for data cleansing Business Spreadsheet, sample-based Single server
- 30. Important questions to ask • Usability – knowing data is more important than knowing tech • Collaboration – essential feature for business users • Data sources – ODBC for NoSQL, cloud, Hadoop not enough • License model – will influence how you adopt the tool • Governance – solving problems or creating new ones? • Complexity – how many moving parts for your end to end analytical process • Vendor viability – crowded market of small players • Ecosystem – no technology is an island
- 31. Market predictions • BI tools build integrated capabilities • But customers want one solution for all tools • ETL vendors try to become “business friendly” • Legacy technology stack is an impediment, not an enabler • Hadoop vendors acquire emerging data prep players • What about data outside of Hadoop? • Opportunity for new approach • Truly self service for the business (no IT required) • Works with all data sources (relational, cloud, NoSQL, Hadoop) • Works with all analytical tools (BI, SQL, R, Python, Spark) • Integrates all layers of the analytical stack

- BI assumes single relational database, but… Data in non-relational technologies Data fragmented across many systems Massive scale and velocity
- Data is the business, and… Era of impatient smartphone natives Rise of self-service BI Accelerating time to market Because of the complexity of modern data and increasing demands for data, IT gets crushed in the middle: Slow or non-responsive IT “Shadow Analytics” Data governance risk Illusive data engineers Immature software Competing strategic initiatives
- Here’s the problem everyone is trying to solve today. You have consumers of data with their favorite tools. BI products like Tableau, PowerBI, Qlik, as well as data science tools like Python, R, Spark, and SQL. Then you have all your data, in a mix of relational, NoSQL, Hadoop, and cloud like S3. So how are you going to get the data to the people asking for it?
- Here’s how everyone tries to solve it: First you move the data out of the operational systems into a staging area, that might be Hadoop, or one of the cloud file systems like S3 or Azure Blob Store. You write a bunch of ETL scripts to move the data. These are expensive to write and maintain, and they’re fragile – when the sources change, the scripts have to change too.

And to do this you build another set of scripts. In the end you’re left with something like this picture. You may have more layers, the technologies may be different, but you’re probably living with something like this. And nobody likes this – it’s expensive, the data movement is slow, it’s hard to change. But worst of all, you’re left with a dynamic where every time a consumer of the data wants a new piece of data: They open a ticket with IT IT begins an engineering project to build another set of pipelines, over several weeks or months
