Initialization blocks run at a specific time or triggered according to a specific condition. The logical table created at the BMM layer can be based on the data from a single physical layer table when it is called a single Logical Table source.
When the specific logical layer table is dependent on the columns of different physical layer tables, it is called Multiple LTS. Most of the time we will be dealing with Multiple LTS. No, it is not mandatory to create the hierarchies for all the tables, we can just define hierarchies to those tables that need to have it. The Siebel variable is the storage parameters that we can link within the metadata and other configuration parameters in the Siebel.
With the help of the variable manager, all the configuration parameters can be loaded into the specific variable depending upon the different environments we are trying to have. This can help us in making the administrative tasks simpler. In general, then you might want to check the joins, referential integrity between tables.
Talk in detail using the below material.. A materialized view is a physical object and replica of one or more master objects. It will refresh in intervals. Building reports on de-normalized data is not the best practice it leads to performance issues but we can build the reports. You will easily find the answer. The repository location can be changed, this must be done when clustering the BI Server.
INI file are. We cannot have outer joins in the Physical layer. We can outer joins in the BMM layer. In the BMM layer — a complex join can be a full inner join or a full outer join or whatever your criteria were, but in the physical layer — a physical join is always an inner join. Need to find the answer still. Be the first to catch the latest happenings of technology with us. About Author. Ravindra Savaram is a Content Lead at Mindmajix.

What do you mean by pipeline? What are the various levels of access authentications? What is a materialized view? What is the default location of a repository file? This course will help you to achieve excellence in this domain. Select the option of Tools Create a report from the catalog manager. Then click the request SQL option from the create report window.
Also, the sales to the physical path should be saved on the computer. Then by selecting the properties for the user option make sure to enable the level of Log to 2.
If so how can we do it? For reports, dashboards, rpd in OBIEE, mention the method of putting changes to production from development? Mention the various kinds of variables that are present on OBIEE 11g and also give explanations regarding them? First, it is the repository variable that is used in the case of the entire repository. Secondly, it is the session variable that is again of two kinds.
How will you create report from two subject areas From the Criteria Pane of the Report Created from First Subject Area come to the bottom of the page and click combine request. How will you Port changes for dashboards,reports,rpd from development to production? Repository stores the Meta data information. With OBIEE Server, all the rules needed for security, data modeling, aggregate navigation, caching, and connectivity is stored in metadata repositories.
Each metadata repository can store multiple business models. Physical — Represents the data Sources 2. Business — model the Data sources into Facts and Dimension and apply business logic 3.
OBIEE life cycle: 1. Gather Business Requirements 2. Identify source systems 3. Build a repository 5. Build dashboards and reports 6. Testing and QA. If you have 3 facts and 4 dimension and you need to join would you recommend joining fact with fact? If no than what is the option? Instead of joining fact with fact we can create one logical table fact and add the 3 fact tables as logical table source in the BMM layer.
What is connection pool and how many connection pools did you have in your last project? Connection pool is needed for every physical database. It contains information about the connection to the database, not the database itself.
Can use either shared user accounts or can use pass-through accounts We can have multiple connection pools for each group to avoid waiting. What is the purpose of Alias Tables? An Alias table is a physical table with the type of Alias.
It is a reference to a physical table, and inherits all its column definitions and some properties from the physical table. A logical table source shows how the logical objects are mapped to the physical layer and can be mapped to physical tables, stored procedures and select statements.
An alias table can be a reference to any of these logical table source types. Alias Tables can be an important part of designing a physical layer. The following is a list of the main reasons to create an alias table: 1. To reuse an existing table more than once in your physical layer without having to import it several times 2.
To set up multiple alias tables, each with different keys, names, or joins 3. To help you design sophisticated star or snowflake structures in the business model layer. How do you define the relationship between facts and dimensions in BMM layer? Using complex join we can define relationship between facts and dimensions in BMM layer.
Did you create any new logical column in BMM layer, how? We can create new logical column in BMM layer. Can you use physical join in BMM layer?
Yes we can use physical join in BMM layer. Can you use outer join in BMM layer? Yes we can. When we are doing complex join in BMM layer in the join properties we have an option to change the type of join to left outer, right outer, full outer or inner.
What is level based metrics? Every metadata repository can store many business models. Siebel Analytics Server can access many repositories. Metadata represents the analytical Model which is created using the siebel Analytics Administration tool. Repository divided into three layer. In the BMM layer,we can create one logical table fact and add the 3 fact table as logical table source.
Java Development Kit JDK , is a software package that contains the minimal set of tools needed to write, compile, debug, and run Java applets. An opaque view is a physical layer table that contain select statement. An opaque view should be used only if there is no other option.
Dimension tables contain descriptions about data analysts which is used as query in the database. Every table contains a primary key that contains one or more columns; each row in a table is uniquely identified by its primary-key value or values. There is no full form for rpd as such, it is just a repository file which is known as Rapidfile Database. We can disable cache in the physical layer, by right clicking on the table there we can have the option which define cacheable.
Init blocks are used for instantiating a session when a user logs in. To make dynamic variable we have to create IB to write sql statement. It Examine relationship between metadata objects like which column in the presentation layer maps to which table in physical layer. We can do Aggrigation navigation ,level base matrics, time series wizard, create new logical column, comlex join.
Oracle BI Enterprise Edition sometimes simply referred to as Oracle Business Intelligence provides a full range of business intelligence capabilities that allow you to :.
Users have their own personal folder My Folders , where they can store the objects that they create. The objects in a personal folder can be accessed only by the user who created and saved the content into that folder. Users can add sub-folders to their personal folders to organize their content in the way that is the most logical to them. You can also store objects in shared folders where other users or groups can access the objects.
