Repository means set of database tables, Business object store security information e.g user, group, access permission, user type etc. , universe information e.g. objects, classes, table name, column name, relation ship etc.and document information

it is centralized and set of data structure that can be stored in databases.basically repository can be made up by 3 domains.

Report Template is a specimen for your future reports.

You create a report from scratch, say make it Master-Detail Report with charts, put your company logo, add some default colors(something like same colors your company uses for its documents, webpages etc.) & then save it as BO Report Template file.

Next time when you are creating new reports, & select use Templates option, your report saved as template will be listed in the box. If you select it, your new report will automatically use all color formats, & table-chart structures, logo....whatever you used in your template report file.

Advantage : 1 time devaelopment of display & structure format, for multiple reports use. i.e. Time Saving. No need of formatting for all standard reports.

ZABO is zero administrator businessobjects , which will be installed on your local m/c when any full client report in opened/edited from infoview . For this you don't require any BO mainkey , key will be installed from BO server.Webi is also called as thin client , where -in you are create BO reports on web browser . Reports are only based on Universe .

We can do this in three ways:
1.alphabetical order-prompts will appear in alphabetical order
2.numeric order-prefix number and they will appear in numeric order
3.date order-prompts will appear date wise
it depends on the type we choose in prompt syntax

Cartesian product is getting incorrect results.
for instance if we have a cham trap or a fan trap n we din't solve them after checking the integrity also we get duplicate results of the same record ie nothing but cartesian product.

ex:-
we have customer,orders,loans classes
orders for one product if the product_price is 150$ it will appear twice in the report due to traps bcoz of the cartesian product thats why to solve the cham trap we create context and in order to solve fan trap we create alias table.

Bo XI R2 versions is used in the BO dashboard work.

The difference between union and group is as follows:
★ Take two tables t1 and t2.
★ In t1 we have columns like a,b,c,d. and t2 has a,d,e,f.
★ Ao union means t1 union t2 i.e getting result from both tables i.e a,b,c,d,e.,f
★ Where as group performs on a individual column in a particular table.

to get good name , fame n earn well amt is top business.

As far as i know we schedule the reports through broadcast agent.

The DENSE_RANK function computes the rank of a row in an ordered group of rows. The ranks are consecutive integers beginning with 1. The largest rank value is the number of unique values returned by the query. Rank values are not skipped in the event of ties. Rows with equal values for the ranking criteria receive the same rank.

The DENSE_RANK function does not skip numbers and will assign the same number to those rows with the same value. Hence, after the result set is built in the inline view, we can simply select all of the rows with a dense rank of three or less, this gives us everyone who makes the top three salaries by department number.

ex:

Give me the set of sales people who make the top 3 salaries - that is, find the set of distinct salary amounts, sort them, take the largest three, and give me everyone who makes one of those values.

SELECT * FROM (
SELECT deptno, ename, sal,
DENSE_RANK()
OVER (
PARTITION BY deptno ORDER BY sal desc
) TopN FROM emp
)
WHERE TopN <= 3
ORDER BY deptno, sal DESC
/

DEPTNO ENAME SAL TOPN
---------- ---------- ---------- ----------
10 KING 5000 1
CLARK 2450 2
MILLER 1300 3

20 SCOTT 3000 1 <--- ! (in case of rank JONES will have 3 and dense rank will have 2)
FORD 3000 1 <--- !
JONES 2975 2
ADAMS 1100 3

30 BLAKE 2850 1
ALLEN 1600 2
30 TURNER 1500 3

We can select either tables or procedures or views as our data to generate our reports.In the designer in bo's we can select tab "insert" n select the particular data source for generating the report through mouse click.

1. Motivation factor
2. Team leader quality
3. Risk handler

No there are only 3 repository domains for BO 6.5 i.e universe, security and document.

There is no such tool available yet for comparing Universes/Reports. The best way to compare Universes is to do check intergity constraints & the compare the outputs.

It is similar to views,it is mainly used to restrict the datas.

Alerts are used to alert some part of the data if any change occurs.

select the part of the data in the report where u want to keep alerts n just click on alerts in the tool bar which is present in the third line from menu bar besides rank
then a window pops up n we ca n give some condition where in if it crosses that an alert is sent.

Alerts means highlights the data.
1. select the cloumn/row
2. apply the alert that is available in tool bar
3. provide the necessary condition
4. Apply it
Tx

Here alert means to highlighted data in a particular report.in every report we can apply alerts situtation like, sales revenue per city wise.here city field we can apply alert,condition like sales revenue >=50,000.

We can create any number of universe, but at a time we can open only one universe, generally number of universes should be equal to number of sub-domains.

You can schedule any report using Business Objects (reporter) .1) Open report in BO2) Select option " File->Send To- BCA"3) Select the BCA name to which report has to be scheduled4) Set other options for report scheduling like time , any macro , user etc.

BusinessObjects Enterprise lets you preview a report using thumbnails. You can request the server to take a snapshot of the first page of the report and return it to the browser as an image file. This image can then be displayed as part of the Report Details page.

To retrieve a thumbnail, a separate page needs to be created because the code that writes an image to the screen erases any text that may have previously been there.

Start BO,
Select "Others" on Data Providers wizard page,
from drop down menu, select "ersonal data files",
specify file location & check the box "First Row contains Column names" this will help you in creating Objects.

click Ok.
Start building your reports.......

Conditions: these retrievals the data based on the condition (universe level)Filter: it brings the data and filter; performance will be slow (report level)

Filters - are used to restrict the number of rows in the output.
Conditions - It wont reduce the Number of Rows, but you can show up data based on some validations.
For Eg: select cust_id from customer where cust_name like 'A%'
Filter is Cust_name like 'A%'.
Condition is also applied at report level.

1. In order to solve fan trap in busines objects we either create alias table or aggregate awareness function

2. Through aggregate navigation we can also select the compatable as well as incompatable objects
Ex:-year, quarter, month, week, day
year:-quarter, month, week, day are compatable objects
quarter:-year?class is incompatable and month, week, day are compatible.

3. We specify the objects in descending order.

In data Warehouse when u change + symbol to - , u would c all the aggregation level in that + this is called rolling down.

So if u again click over that - it would again compressed back to +. This is call drill up.
your Aggregation levels woudl b like
Year>Month>Week>Day>Hour>Minutes>Seconds.
So by changing the symbol from - to + at month aggregation level u can drill up.

Object store is nothing but the container of object which is created after rpt file run once.
