Steps to create Universe without using Fact Table

Dear All,
i am confronting with a problem by creating an Universe.
The problem is that we do no have any fact table.
Could you please explain the steps for creating an universe without fatc table?
Thanks
Pat

The first thing to do is identify the tables in your schema that contain measures. These will be your base tables for contexts.
Then identify all the tables that relate to each of your candidate fact tables.
You may identify two related tables, both with facts in, which would give you a fan trap.
Say you have a schema with only three tables and they are related as: T1 -< T2 -< T3
T2 and T3 both have measure columns.
What you would need to do is create an alias of T2 (AT2) and join it to T2.
You would then have two contexts, T1-< T2 , T2-< T3 and T1-<T2, T2- AT2
For objects from T2, derive the dimensions from T2 and the measures from AT2.
Beyond that, it's fairly standard.
If you have a data schema it is going to be much easier for you.

Create Report Painter using LIS table

Hi Expert,
I'n new in ECC version but I found we can create report painter using LIS table,
but I'm not success to create report without error or debug
Anybody have the documentation about it ? or tell me how it works ...
Please ..urgent...need to tell client about it..
Thanks

Hi,
I have not worked on it but you can try this out:
TCODE for report writer table is GRCT.
There You need to add your z fields in some pre-defined structure like CCSS and then activate the structure and then activate characteristics.
NOTE: 24 charcter is max. length for the characteristics.

What is the best practice for creating primary key on fact table?

what is the best practice for primary key on fact table?
1. Using composite key
2. Create a surrogate key
3. No primary key
In document, i can only find "From a modeling standpoint, the primary key of the fact table is usually a composite key that is made up of all of its foreign keys."
http://download.oracle.com/docs/cd/E11882_01/server.112/e16579/logical.htm#i1006423
I also found a relevant thread states that primary key on fact table is necessary.
Primary Key on Fact Table.
But, if no business requires the uniqueness of the records and there is no materilized view, do we still need primary key? is there any other bad affect if there is no primary key on fact table? and any benifits from not creating primary key?

Well, natural combination of dimensions connected to the fact would be a natural primary key and it would be composite.
Having an artificial PK might simplify things a bit.
Having no PK leads to a major mess. Fact should represent a business transaction, or some general event. If you're loading data you want to be able to identify the records that are processed. Also without PK if you forget to make an unique key the access to this fact table will be slow. Plus, having no PK will mean that if you want to used different tools, like Data Modeller in Jbuilder or OWB insert / update functionality it won't function, since there's no PK. Defining a PK for every table is a good practice. Not defining PK is asking for a load of problems, from performance to functionality and data quality.

Insert XML file into Relational database model without using XMLTYPE tables

Dear all,
How can I store a known complex XML file into an existing relational database WITHOUT using xmltypes in the database ?
I read the article on DBMS_XMLSTORE. DBMS_XMLSTORE indeed partially bridges the gap between XML and RDBMS to a certain extent, namely for simply structured XML (canonical structure) and simple tables.
However, when the XML structure will become arbitrary and rapidly evolving, surely there must be a way to map XML to a relational model more flexibly.
We work in a java/Oracle10 environment that receives very large XML documents from an independent data management source. These files comply with an XML schema. That is all we know. Still, all these data must be inserted/updated daily in an existing relational model. Quite an assignment isn't it ?
The database does and will not contain XMLTYPES, only plain RDBMS tables.
Are you aware of a framework/product or tool to do what DBMS_XMLSTORE does but with any format of XML file ? If not, I am doomed.
Constraints : Input via XML files defined by third party
Storage : relational database model with hundreds of tables and thousands of existing queries that can not be touched. The model must not be altered.
Target : get this XML into the database on a daily basis via an automated process.
Cheers.
Luc.

Luc,
your Doomed !
If you would try something like DBMS_XMLSTORE, you probably would be into serious performance problems in your case, very fast, and it would be very difficult to manage.
If you would use a little bit of XMLType stuff, you would be able to shred the data into the relational model very fast and controlable. Take it from me, I am one of those old geezers like Mr. Tom Kyte way beyond 40 years (still joking). No seriously. I started out as a classical PL/SQL, Forms Guy that switched after two years to become a "DBA 1.0" and Mr Codd and Mr Date were for years my biggest hero's. I have the utmost respect for Mr. Tom Kyte for all his efforts for bringing the concepts manual into the development world. Just to name some off the names that influenced me. But you will have to work with UNSTRUCTURED data (as Mr Date would call it). 80% of the data out there exists off it. Stuff like XMLTABLE and XML VIEWs bridge the gap between that unstructured world and the relational world. It is very doable to drag and drop an XML file into the XMLDB database into a XMLtype table and or for instance via FTP. From that point on it is in the database. From there you could move into relational tables via XMLTABLE methods or XML Views.
You could see the described method as a filtering option so XML can be transformed into relational data. If you don't want any XML in your current database, then create an small Oracle database with XML DB installed (if doable 11.1.0.7 regarding the best performance --> all the new fast optimizer stuff etc). Use that database as a staging area that does all the XML shredding for you into relational components and ship the end result via database links and or materialized views or other probably known methodes into your relational database that isn't allowed to have XMLType.
This way you would keep your realtional Oracle database clean and have the Oracle XML DB staging database do all the filtering and shredding into relational components.
Throwing the XML DB option out off the window beforehand would be like replacing your Mercedes with a bicycle. With both you will be able to travel the distance from Paris to Rome, but it will take you a hell of lot longer.

Steps to create f4 help for a table

steps to create f4 help for a table

These are the steps you have to take first:
1. Please elaborate, your question does not all too clear.
2. Search on SCN.
3. Search on help.sap.com (for creating F4 search help).
I guess you get the picture. Creating an F4 help is quite easy (you can find that on SCN for sure), but what do you mean by
for a table
1.Do you want to create a field which has an F4 help for searching tables or
2. is this field part of a table and you need to have a search help for that field of that table in order to select some sort of value
3. Is this a custom table.
4. Is this a custom field for which F4 help should be added.
5. Won't a domain value do.
6. etc.

Star schema without a fact table?

Hi,
I'm preparing my warehouse for using with Discoverer and my question is about the star schema.
- Is a star schema directly associated with data warehouse?
- Can I talk about a star schema if a) I do not have a fact table (no summarized values) and b) if I do not have a dimension of time?
The problem is, I'm thinking of usine Discoverer but should I use it if it's not connected to a data warehouse?
As I told, I'd like to modelized my data "like" a star schema but my "center table" will contain only the foreign key of my dimensions; no time dimensions, no aggregate data in the center table (fact table).
Is there another word for the model I'd like to do?
Thank in advance.

Hi,
Is a star schema directly associated with data warehouse?Not really, a star schema is just one where there is one large fact table joined to many smaller dimension tables using key fields. You usually see this in data warehouses.
Can I talk about a star schema if a) I do not have a fact table (no summarized values) and b) if I do not have a dimension of time?A star schema must have a fact table but it doesn't need contain summarised values or a time dimension.
You can use Discoverer with any Oracle database, it doesn't have to be a data warehouse.

How to load external data without using external tables

Hi,
I'm asked to develop an ETL for loading external data into a database but, unfortunately, the vers. is 8i so I can't use external tables.
I know that it's possible by using SQL-Loader. What I want to know is whether there's another way in 8i to load external data from a text file or a CSV file directly with a stored procedure without having to write CTL of SQL-Loader on the server. I mean, is there a way to write everything on the database the same manner I'd do whether I wrote data from a table to a file using for example UTL_FILE or the unique way is to write control files of SQL-Loader directly on the server?
Thanks!

Mark1970 wrote:
Thank you very much Karthick
I didn't know I could use UTL_FILE also for reading files. I've always use it only for writing data into external files.Yes you can use UTL_FILE to read. The version of oracle you are using i last used in 2004 :) Still remember giving the OS path of the file to open the file. That is long gone now. Its surprising that you are still in 8i.

Determine when a database was backed up without using MSDB tables?

Hi all,
I was wondering if there was another method to determine when a database was last backed up without using the backup history tables in msdb? whether using DBCC DBINFO, DBCC PAGE on a specific database page...etc.
Also, when restoring a database, is there a trace flag you can use to force restore details to be written to the error log?
John M. Couch

The backup success message is written to the log, but the question is whether you can get restore information outside of successful restore messages to the log. i.e. backup file header information
And on a server I just restored a database too, if its not the source server, there will be no backup information in MSDB for the database or log file. Is there something internal to the database that would have that information?
John M. Couch
if you restore the database -- your msdb database has restore tables, that will tell you where you got the backup from etc..
select * from msdb.dbo.restorehistory
if the backup is from another server, use linked server in the msdb fr backup tables(not restore tables)
refer https://sqlwhisper.wordpress.com/2015/01/08/database-restore-report/
also, AFAIK,i do not think backup information is stored in the database, i would be curious know
as well.

Relationship between Dimension without linking Fact table

Hi,
My question is like I have five dimensions connected to a fact table through primary - foreign key(Composite Key) relationship. Will this referential integrity help if I want some information between two dimension which are not linked directly and I am not
including any measures from fact table .
Example: Suppose I have customer, Product and Manufacturer Dimensions all linked to a fact table but not linked to each other directly but can I get right result when I want to know what are the manufacturer for each product? or list of
customers using a particular product. Will the referential integrity work ? since they all are related in fact table.
regards
Sanjoy ghosh

Hi Sanjoy -
The answer to your questions depends on your dimensional design and exactly what the fact table represents. Fact tables naturally capture the intersection of the different dimensions. This is true whether you physically implement a
PK - FK relationship in the relational db.
In your case, since customer is involved, sounds like a sales transaction fact. If that's true, you can easily join from customer, through the fact, to the product dimension, to get the list of customers that purchased a particular product.
For the manufacturer for each product, a sales transaction fact will not necessarily answer this question completely. Particularly in the case of products that have no sales for a given period, and thus, don't have any fact records to join from manufacturer
across to product. If you need to solve this question, you have some other options:
- flatten the Manufacturer directly into the Product dimension as attribute of the product (probably the simplest approach and allows you to remove a key from the fact)
- embed the Manufacturer key directly in the Product dimension (if you need the Manufacturer dimension separate for use with other events / facts and more detailed dimensionality - i.e., detailed attributes about the Manufacturer that wouldn't need
to be flattened onto the product)
- build a factless fact that captures the products offered by a given manufacturer at a given point in time (perhaps representing various products catalogs and associated dates. This would allow you to capture rich details about each dimension separately
and use the factless fact to record)
Let me know if that helps.

How to create links without using widgets

I am using a vertical menu via the widget, but want to create a submenu without using the widget. btw, the rollover feature is fun

To create a sub menu without using the sub menus in the menu widget you can combine the menu widget and the tooltip widget to create your menu.
There is plenty of examples and widgets that do what you are asking if I understand correctly at the Muse exchange and places like musegrid.com.

Create index without using temp tablespace

Hello,
i have a great table with over 2.000.000.000 rows. Therefor i want to create an index on column1:
CREATE INDEX "SCHEMA"."INDEX_TABLE1" ON "SCHEMA"."TABLE1" ("STR1")
PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS NOCOMPRESS LOGGING
STORAGE( INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
PCTINCREASE 0 BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
TABLESPACE "USERS" ;
If i execute this my temp tablespace will be used and if its full (max 20gb) the creation will be aborted.
Where is my fault to create the index?

If this is the complete definition of the table, and if (str1, str2) are unique, and this really is the only way you use the table, then it looks as if your STRATEGIC move would be to rebuild the table as a hash partitioned IOT with something like 128 partitions. Since you probably can't do that in the short-term you could create a hash partitioned index on the table (assuming you have paid the partitioning licence) with enough partitions that you can create each one separately. Something like:
SQL> create index t1_i1 on t1(n1, n2, n3) unusable global partition by hash (n1, n2) partitions 4;
Index created.
SQL> select index_name, partition_name from user_ind_partitions;
INDEX_NAME           PARTITION_NAME
T1_I1                SYS_P8713
T1_I1                SYS_P8712
T1_I1                SYS_P8711
T1_I1                SYS_P8710
4 rows selected.

Index altered.

Help required to create portal without using any vendor specific API's

Hi All,
I am trying to develope a portal without using any vendor specific API or tool like Weblogic workshop or Vignette Wizard. I would like to know whether Sun Microsystem provides any API for developing portal. I would also appreciate if I can get few links for developing portal using java API's...
Thanks in advance...
Dgk

Sure Sun provides the tools: it is called the compiler. Now all you need to do is write the code for a portal. But since there are vendor specific solutions available that could make your life a lot easier, writing one yourself is like reinventing the wheel.
Pardon my mild sarcasm, but avoiding API's not developed by Sun is not the general idea behind the Java platform. You are encouraged to use those API's.
