When you read the table to do reporting, for example, all the values of a column are stored together, so if we need to find "all the rows for January 6th, 1988" then we don't need to look at the whole file, just the first part, which contains the first column. There's no need to read, skip forward, check, read, skip forward, and so on. SAP HANA takes this one step further, storing each column in a separate file: Col1:19880101198801021988010319880104198801051988010619880107 Col2:5671234 Col3:LAXLAXLAXLAXLAXLAXLAX Col4:JFKJFKJFKJFKJFKJFKJFK Col5:305301311282300294284 Col6:103-4370416 Col7:1547150-20 If SAP HANA needs to answer the query we saw earlier (the time of the flight from LAX to JFK on the 6th of January 1988), then the server can again cut the query into several components: FlightDate = 19880106 Origin = LAX Destination = JFK Information to return = FLIGHTDATE These components can be run in parallel, one CPU handling each of the tests, finding the row numbers which match: FlightDate = 19880106 – Matching row(s) = 6 Origin = LAX – Matching row(s) = 1,2,3,4,5,6,7 Destination = JFK – Matching Row(s) = 1,2,3,4,5,6,7 Finally all that needs to be done is to find the union of each sub-result set (row 6), and return the final result (which is 294 minutes).
In this way you have one instance where the state of development might be relatively unstable because developers are continually making changes to the information models, and a second instance where only developments that are considered complete are present, and which is therefore more stable. Clicking on Next will make the Studio validate that it can connect to the server whose address you specify, and will prompt you for your connection information: In this example, we're connecting to the server using a provided username and password.
Chapter 7, Hey! That's My Data! – Authorizations in SAP HANA, introduces the notion of authorizations in the SAP HANA system, allowing you, as a developer, to dictate who can access which object in the database, and even which values (that you have created in the different modeling views) can be seen by which of your users. You will learn that user groups can be created by developing authorization roles; you will create a database user to be able to test the authorizations you create. Chapter 8, On Another Level – Hierarchies in SAP HANA, examines the notion of hierarchies as they apply to data visualization, showing the different hierarchy types you can create with SAP HANA.
