different sections, results and how to interpreter the SQL, with common
table expressions, generated by MicroStrategy]](https://image.slidesharecdn.com/a28f4068-8a13-4088-aca4-25e3af2cc8b2-160616120538/85/Microstrategy-for-Data-Engineers-31-320.jpg)
Microstrategy for Data Engineers
- 1. MicroStrategy for Data Engineers Francesco Mucio London, 10 June 2016
- 2. What is MicroStrategy - Born in 1989 - BI Reporting Tool - The last of the old one not acquired and not acquiring - Etc...
- 3. MicroStrategy Architecture dwh MicroStrategy iServer web server with MSTR webapp user MicroStrategy metadata
- 4. What MicroStrategy do wants! - A Dimensional model (snowflake flavour) - Dummy Records for Null values - Good Data Quality
- 5. Star vs Snowflake schema fact dimension 2 dimension 4 dimension 5 dimension 3 dimension 1 fact dimension 2 - lvl1 dimension 4 dimension 5 - lvl1 dimension 3 dimension 1 - lvl2 dimension 1 - lvl1 dimension 5 - lvlb dimension 5 - lvl2a dimension 2 - lvl2 dimension 2 - lvl3
- 6. Star vs Snowflake schema Star Schema Dimension Snowflake Schema Dimension date_id day_of_week month_id month_name quarter_id 20160101 Friday 201601 January 20161 20160102 Saturday 201601 January 20161 20160103 Sunday 201601 January 20161 date_id day_of_week month_id 20160101 Friday 201601 20160102 Saturday 201601 20160103 Sunday 201601 month_id month_name quarter_id 201601 January 20161 201601 January 20161 201601 January 20161 quarter_id quarter_name 20161 2016-Q1 20161 2016-Q1 20161 2016-Q1 DIM_CALENDAR DIM_DATE DIM_MONTH DIM_QUARTER
- 7. MicroStrategy Objects ➔ Schema Objects ◆ mapping of physical objects: Tables, Columns, etc… ➔ Public Objects ◆ application objects: Metrics, Reports, Dashboards, etc…
- 8. MicroStrategy Schema - Tables A MicroStrategy Tables maps a database table or view. Multiple physical tables can be mapped as partition of a MicroStrategy table.
- 9. MicroStrategy Schema - Logical Tables A Logical Table allows to use a query as a table. In the definition you must: - Set the database instance to use - Map all the columns returned by you query
- 10. MicroStrategy Schema - Attributes - A level of a Dimension. - Needs a lookup table. - Can have parents and children. - Has multiple forms. - Each form can have multiple expressions.
- 11. MicroStrategy Schema - Facts A numeric* value that needs to be measured by the business. Can have multiple expressions. Doesn’t know how it will be used. Can be extended, if required. * usually
- 12. MicroStrategy Schema - Facts A numeric* value that needs to be measured by the business. Can have multiple expressions. Doesn’t know how it will be used. Can be extended, if required. * usually
- 13. MicroStrategy Schema - Advanced topics Expressions can contain intra-row operations. Expressions can contain 1-1 functions. Attributes determine the Logical Weight of a table. Transformations defines ways to transform an attribute element to one or more elements of the same attribute: i.e. Previous Year or Year-to-date.
- 14. MicroStrategy Metrics A Fact defines which column of which table we want to use. A Metric defines what, how, where, when to do with that fact/column.
- 15. MicroStrategy Metrics How to aggregate? The Formula defines the kind of aggregation we want to use. Metrics can be compound of other metrics: Profit = Revenue - Cost
- 16. MicroStrategy Metrics Where to aggregate? The Level allows to fine tune the aggregation, depending on attributes/dimension. Filtering: ignore or not a where condition? Grouping: aggregate using the standard grouping or not.
- 17. MicroStrategy Metrics When to aggregate? Condition: a where condition. This can become a CASE statement or a separated sub-query. Transformation: a rule to transform an attribute value
- 18. MicroStrategy Reports Reports or Datasets are glorified SQL queries. Components: - Report Objects - Filter - Template
- 19. MicroStrategy Reports OLAP capabilities: - Moving objects in template - Moving objects between Report object and template - Modify the View Filters Non-OLAP: - Add new objects - Change the Report Filter
- 20. MicroStrategy Reports: SQL ... Pass0 - Query Pass Start Time: 09/06/2016 23:22:50 Query Pass End Time: 09/06/2016 23:22:52 Query Execution: 0:00:01.78 Data Fetching and Processing: 0:00:00.00 Data Transfer from Datasource(s): 0:00:00.00 Other Processing: 0:00:00.02 Rows selected: 131 with gopa1 as (select /*Administrator - job 1049 - New Report - 20160609:232250*/ a13.PROFILE_GENDER_ID PROFILE_GENDER_ID, a12.ACQUISITION_BRAND ACQUISITION_BRAND, a11.PROFILE_REGISTERED_DT Reporting_Date_DT, count(distinct a11.PROFILE_USER_ID) n_users from MICRO.MS_F_PROFILE_REGISTRATION a11 ...

- 21. MicroStrategy Intelligent Cubes In memory copy of a query result. Can be also partially re-published. A report based on an Intelligent Cubes: - has access only to that cube objects - generates an MDX query Dynamic Sourcing allows also not cube-based reports to use available cubes.
- 22. MicroStrategy Reports - Free Form SQL A FFSQL is a report created starting from an existing query. Very good for prototyping Very bad for maintenance You can also have FFSQL cubes.
- 23. MicroStrategy Reports - Free Form SQL Things to define: - Database Instance - Query - Free form objects
- 24. MicroStrategy Filters Filters are like where conditions. Multiple filters can be combined, using AND, OR, and NOT, to make complex ones.
- 25. MicroStrategy Filters: Advanced Reports can be used as filters. Set Qualification are used to filter attributes based on elements not always present in the final report.
- 26. MicroStrategy Filters: Advanced gopa1 as (select /*Administrator - job 2158 - All TYPE REG Active with Revenue - 20160610:132345*/ a11.PROFILE_USER_ID PROFILE_USER_ID from MICRO.MS_F_PROFILE_REGISTRATION a11 group by a11.PROFILE_USER_ID having sum(a11.PROFILE_PHOTOS_TOTAL_COUNT) >= 3.0 ), gopa9 as (select /*Administrator - job 2158 - All TYPE REG Active with Revenue - 20160610:132345*/ a15.REGISTRATION_METHOD REGISTRATION_METHOD, a13.PROFILE_REGISTERED_DT first_click_date, a14.ACQUISITION_BRAND ACQUISITION_BRAND, a14.ACQUISITION_TRANSLATION ACQUISITION_TRANSLATION, a13.PROFILE_GENDER_ID PROFILE_GENDER_ID, count(distinct a11.PROFILE_USER_ID) WJXBFS1 from INGRES.MS_DIM_PROFILE a11 join gopa1 pa12 on (a11.PROFILE_USER_ID = pa12.PROFILE_USER_ID) join INGRES.MS_DIM_PROFILE a13 on (a11.PROFILE_USER_ID = a13.PROFILE_USER_ID) join ingres.DIM_ACQUISITION_PLATFORM a14 on (a13.PROFILE_ACQUISITION_PLATFORM = a14.ACQUISITION_PLATFORM) join ingres.MS_DIM_PROFILE_EXTRA a15 on (a11.PROFILE_USER_ID = a15.PROFILE_USER_ID) where (a13.PROFILE_REGISTERED_DT >= DATE '2016-01-01' and a13.PROFILE_IS_TEST_USER_ID = 0 and a14.ACQUISITION_TRANSLATION in ('Android', 'iOS', 'Webapp', 'Windows') and a14.ACQUISITION_BRAND in ('Badoo')) group by a15.REGISTRATION_METHOD, a13.PROFILE_REGISTERED_DT, a14.ACQUISITION_BRAND, a14.ACQUISITION_TRANSLATION, a13.PROFILE_GENDER_ID )
- 27. MicroStrategy Dashboards A more modern tool for data exploration. - Simpler to develop and use - Slick design - Just nicer
- 29. MicroStrategy Dashboards A dashboard has at least one tab. A tab has one or more panels. A panel contains visualizations. Each visualization is based on one or more datasets.
