Navigating Oracle Business Intelligence: A Comprehensive Guide to Data Analysis and Report Generation - Certbolt

In the intricate tapestry of enterprise data management, the capacity to meticulously analyze vast datasets and to generate insightful reports stands as an indispensable cornerstone for informed decision-making. This discourse will meticulously delineate the intricate methodologies involved in scrutinizing data within the Oracle Business Intelligence Enterprise Edition (OBIEE) ecosystem, with a particular emphasis on the practical steps for crafting compelling reports. We shall embark on a detailed exploration of the procedural nuances involved in establishing an End User Layer (EUL) and constructing business areas, vital components for democratizing data access. Furthermore, we will delve into the interactive capabilities of Discoverer Plus IDE and Discoverer Viewer, culminating in an exposition on leveraging Oracle Reports for robust enterprise reporting.

Laying the Foundation: Establishing the End User Layer (EUL) with Discoverer Administrator

The creation of an End User Layer (EUL) is a fundamental prerequisite for enabling intuitive data exploration and reporting within the Oracle Discoverer environment. The EUL acts as a semantic layer, abstracting the complexities of the underlying relational database schema into business-friendly terms, thereby empowering non-technical users to access and analyze data without needing to understand intricate SQL queries or database structures. The following methodical steps meticulously outline the process of constructing such an EUL utilizing the formidable capabilities of Discoverer Administrator:

Initiating Database Permissions through SQLPlus

The foundational step necessitates the conferment of appropriate database privileges to the designated user account that will interact with the Discoverer environment. This ensures the user possesses the requisite authority to create database objects essential for the EUL.

Launch SQLPlus and Connect as System Administrator: Commence by invoking the SQLPlus command-line interface. Establish a secure connection to your Oracle database instance utilizing credentials endowed with system administrative privileges, typically by connecting as sysdba. This privileged access is crucial for modifying user permissions at a fundamental level.

Granting View Creation Privileges: Upon successful connection, issue the following explicit SQL command to bestow the CREATE VIEW privilege upon the specified user. This privilege is paramount as the EUL internally constructs database views to represent the business areas and items for Discoverer. GRANT CREATE VIEW TO your_chosen_username; Replace your_chosen_username with the actual database user who will own the EUL. This declarative statement ensures that the schema associated with this user can programmatically generate necessary database views.

Terminating SQLPlus Session: After the successful execution of the GRANT command, you may judiciously terminate your SQLPlus session. The necessary permission has now been conferred, and further operations will transition to the Discoverer Administrator interface.

Accessing Discoverer Administrator and EUL Management

With the requisite database permissions in place, the next phase involves launching Discoverer Administrator and navigating to its EUL management interface. This application is the central hub for defining and managing the semantic layer that underpins Discoverer’s analytical capabilities.

Launching Discoverer Administrator: Navigate through your operating system’s application menu structure. On Windows, this typically involves traversing Start | Programs | Oracle Business Intelligence Tools-BIToolsHome1 | Oracle Discoverer Administrator. This action will invoke the application’s primary connection dialog.

Establishing Database Connection: Upon the appearance of the «Connect to Oracle Business Intelligence Discoverer Administrator» dialog, meticulously input the designated username and password pair (e.g., your_chosen_username/your_password) corresponding to the database user account previously granted privileges. Concurrently, you must accurately furnish the service name of the underlying Oracle database instance. This information directs Discoverer Administrator to the correct database.

EUL Existence Verification and Creation Prompt: Subsequent to clicking the «Connect» button, Discoverer Administrator will perform an internal verification to ascertain the existence of at least one EUL accessible to the connected user. Should no accessible EUL be detected, the system will intuitively present a prompt inquiring whether you wish to initiate the creation of a new EUL at this juncture. Respond affirmatively by clicking «Yes,» which will consequently invoke the «EUL Manager» dialog. Conversely, if an EUL is already accessible, immediate connection to Discoverer Administrator will ensue. In this scenario, you can manually access the «EUL Manager» dialog by selecting Tools | EUL manager… from the application’s menu bar.

Initiating New EUL Creation: Within the «EUL Manager» dialog, locate and click the «Create a EUL…» button. This action will orchestrate the launch of the «Create EUL Wizard,» a guided multi-step process designed to streamline the EUL creation workflow.

User Selection for EUL Ownership: In the inaugural step of the Create EUL Wizard, you are presented with the option to select a specific user from the comprehensive roster of available database users. This user will effectively «own» the EUL, meaning the EUL objects will be created under their schema. To facilitate this selection, click the «Select…» button within the wizard screen, which will open the «Select User» dialog.

Identifying and Choosing the EUL Owner: Within the «Select User» dialog, click the «Go» button to populate the «Results» box with a comprehensive enumeration of all database users to which you have access. From this generated list, judiciously select your designated EUL owner (e.g., your_chosen_username) by double-clicking the entry. This action will confirm your selection and return you to the Create EUL Wizard.

Finalizing EUL Creation: Upon the successful selection of a user, the «Finish» button within the Create EUL Wizard should become interactively enabled. Click this button to instruct Discoverer Administrator to commence the asynchronous process of EUL creation. This background operation is typically expedited, concluding in less than a minute. Upon its successful culmination, a confirmatory message will be displayed, indicating the successful instantiation of the EUL.

Closing the EUL Manager: Once the EUL creation notification is received, judiciously close the «EUL Manager» dialog by clicking its «Close» button. The foundational semantic layer for your data analysis endeavors is now established, paving the way for defining business-oriented data views.

This meticulous process ensures that the Discoverer environment is correctly configured with a robust semantic layer, translating the intricate world of database tables and columns into meaningful business concepts that empower broader analytical capabilities within the organization.

Structuring Insights: Crafting Business Areas within Discoverer Administrator

With the foundational End User Layer (EUL) firmly established, the subsequent critical phase involves the methodical creation of business areas. A business area in Discoverer serves as a logical grouping of related database tables and views, presented to end-users with intuitive, business-friendly names and organized hierarchies. This abstraction simplifies data exploration significantly, allowing users to focus on business questions rather than data schema complexities. The following steps detail the procedure for constructing a business area within the Discoverer Administrator interface:

Accessing the Administration Tasklist

Upon the successful closure of the EUL Manager dialog, your Discoverer Administrator interface should naturally transition to display the Administration Tasklist dialog.

Once the user is selected, click «Next» to progress to the «Step 3» screen of the wizard, which presents the available tables.

Incorporating Orders Table in Step 3: Within the «Step 3» screen of the wizard, meticulously expand the list associated with the selected user (e.g., usr) in the «Available» box. Locate and select the «orders» item, representing a database table containing order information. Then, click the «►» button to transfer this «orders» table to the «Selected» box, indicating its inclusion in your nascent business area. Subsequent to this inclusion, click «Next» to proceed to the «Step 4» screen of the wizard.

Proceeding to Final Step in Step 4: In the «Step 4» screen of the wizard, which typically presents a summary or configuration options related to the selected items, simply click the «Next» button to move onward to the culminating screen of the wizard. This final step is where you assign a meaningful name to your newly formed business area.

Naming and Finalizing the Business Area in Step 5: In the «Step 5» screen of the wizard, which is the final configuration stage, enter a descriptive and intuitive name for your business area. For instance, input «OrdersBusinessArea» into the «What do you want to name this business area?» field. Upon entering the desired name, click the «Finish» button. As a direct consequence of this action, a multi-tabbed window, aptly titled «End User Layer USR,» will dynamically appear within the Discoverer Administrator interface.

Exploring the Newly Created Business Area

The newly opened «End User Layer USR» window is your portal to understanding and further refining the structure of your business area. This interface provides granular views into its components.

Navigating the End User Layer USR Tabs: By meticulously exploring the various tabs within the «End User Layer USR» window, you can familiarize yourself intimately with the inherent structure of your recently created business area. For example, if you navigate to the «Hierarchies» tab and subsequently expand the «Orders BusinessArea» list, you will observe how the orddate field, which was inherited directly from the underlying orders table, has been intelligently «shredded» into a default date hierarchy. This automatic hierarchy creation significantly enhances the analytical capabilities for temporal data, allowing users to drill down from years to quarters, months, and days with ease.

Exiting Discoverer Administrator: Once you have concluded your exploration and are satisfied with the configuration of your new business area, you can gracefully terminate your Discoverer Administrator session by selecting the File | Exit menu item.

The creation of a business area is a pivotal step in bridging the gap between raw database tables and the analytical needs of business users.
