Source Data
...
After creating new account you need to import data which you want to analyze. There are two ways how to import data - either upload source data files or import data from source application for which eazyBI data import is defined.
Source Files
Currently import from CSV format files is supported (other formats will be supported later, please write feedback if you want support of some specific format). After upload of source data file you need to define mapping from source file columns to cube dimensions and measures (see Cubes, Dimensions and Measures below).
Cubes
...
Imported data are stored in multi-dimensional data cubes. Cubes contain fact data that are divided by dimensions and each detailed fact "cell" contains measure values about that fact.This is example of Sales cube that has Customers, Products and Time dimensions and has measures Sales amount and Units sold. Each detailed cube "cell" contains sales amount and units sold for particular product, customer and time period:
...
...
It is easy to illustrate cube with three dimensions but you can have as many dimensions and as many measures as you need in one data cube.
All measures in the same cube share the same dimensions. If in one account you want to store different types of measures that do not share the same dimensions then you can create several different cubes.
Dimensions
...
Typical cube dimensions are Time, Customers, Products, Locations, Employees, Projects etc. Use dimensions that are best suited to your business domain.

Izejas dati

Pēc jauna konta izveidošanas, nepieciešams importēt analizējamos datus. Standard-BI atbalsta jebkuru atbilstoši strukturētu datu analīzi, tādēļ lietoājam ir pieejamas divas importa opcijas:
Importējot datus, kas iegūti tieši no HansaWorld produkta jums tikai jānorāda, kuru failu vēlaties importēt. Importējot citas struktūras datus, ar tiem jāveic noteiktas apstrādes darbības. Abos gadījumos datu imports notiek, augšupielādējot izejas datu failus Standard-BI. |
Izejas faili
Standard-BI ir speciāli pielāgota noteiktu datu importam tieši no HansaWorld produktiem.
Pēc īsa apmācības kursa iziešanas Standard-BI lietotāji var veikt arī jebkuru citu datu importu no CSV formāta failiem. Šāda importa gadījumā lietotājam jāveic importējamā faila datu kolonnu sasaiste ar datu kuba dimensijām un rādītājiem. (skat. Datu kubi, Dimensijas un rādītāji zemāk).
Tip |

Importējot atbalstītos standarta HansaWorld failus šī sasaiste tiek veikta automātiski pēc iepriekšnoteiktiem loģiskiem principiem. |

Dotais attēls ar trīs dimensijām un diviem rādītājiem (mērvienībām) attēlots tikai piemēra uzskatāmībai. Standard-BI būvētajos kubos var tikt izmantots neierobežots dimensiju un rādītāju daudzums. Visām viena datu kuba rādītāji (mērvienības) tiek sadalītas pa noteiktā kuba dimensijām. Ja vienā kontā jūs vēlaties izmantot rādītājus (mērvienības), kuru dimensijas atšķiras no citiem rādītājiem, Standard-BI piedāvā iespēju izveidot neierobežotu datu kubu

Dimensijas

---|---|---|---|---|

Tipiskās datu kuba dimensijas ir Laiks, Klienti, Preces, Reģioni/Noliktavas, Projekti, Darbinieki un citas. Datu kubā informācia var tikt par katru noteiktā Katrai dimensijai iespējams detalizētais un hierarhiskais datu glabāšanas sadalījums par katru dimensijas biedru. Detalizētas informācijas uzglabāšanas gadījumā tā tiek saglabāta maksimāli detalizētā līmenī (par pamatu ņemot mazāko iespējamo dalījumu) par visiem dimensijas biedriem. Hierarhiskas datu glabāšanas gadījumā informācijas glabāšanai var noteikt vairāku līmeņu hierarhiju. Piemēram, Klienta dimensija var ietvert valsts, novada, pārdevēja un klienta nosaukuma līmeņus. |

All measures are automatically aggregated (typically as sum of detailed level values) in upper hierarchy levels. E.g. looking at Sales amount measure at Country level will give total sales amount for this country. Typically each dimension has All level with one All member which aggregates all dimension members. When you upload source file with date (or date & time) column then automatically time hierarchy will be constructed for corresponding dimension. Time hierarchy will have Year, Quarter, Month and Day levels which can be used to get totals of measures at selected time period level. |
Measures
Align | ||||
---|---|---|---|---|
| ||||
Measures typically are integer or decimal values that can be accessed either at detailed dimension member level or can be aggregated at higher dimension levels. Typical measure examples could be Sales amount, Units sold, Cost amount, Transactions count etc. |
Calculated members
Align | ||||
---|---|---|---|---|
| ||||
Sometimes you want to calculate new measures from other existing cube measures - these are called calculated measures. For example, you could define Profit calculated measure as Sales amount measure minus Cost amount measure. And then you could also define Margin % calculated measure as Profit measure diveded by Sales amount measure (and display result as percentage). You can also define calculated members in other dimensions. For example, you could define in Customers dimension new calculated member North America as sum of USA and Canada members. Calculated member formulas are defined using MDX language. Basic arithmetic formulas can be created very easily but by learning other MDX functions you will be able to create any calculated members you need. Read more about creating calculated members. |
Analyze and create reports

After importing data from source files or source applications you can go to Analyze tab and start to explore data in create cube. You can start creating table reports by dragging needed dimensions to columns, rows and pages and exploring your data at different dimension levels. After selecting needed data in table report you can switch to different chart reports to explore your data in more visual way. When you have created report layout that you want to use frequently you can save this report with given name. When later you will open saved report then you will get latest results drom data cube using saved report layout.
