The five key stages of Business Intelligence:
► Data Sourcing
► Data Analysis
► Situation Awareness
► Risk Assessment
► Decision Support
Universe is a semantic layer between the database and the user interface (reports).
A good OLAP interface has writes an efficient sql and reads an accurate data from db.To design and architect having good knowledge on DB understanding the report requirements.
► Reporting & Analyzing tool
► Universe creation
► database interaction
Supervisor - For Administrative purposes
Webintelligence - Access of report data through internet
BroadCast Agent - For scheduling the reports
Data Integrator - The ETL tool of Business Objects, designed to handle huge amounts of data
Designates a category of applications and technologies that allow the collection, storage, manipulation and reproduction of multidimensional data, with the goal of analysis.
MOLAP - Multidimensional OLAP.
This term designates a cartesian data structure more specifically. In effect, MOLAP contrasts with ROLAP. Inb the former, joins between tables are already suitable, which enhances performances. In the latter, joins are computed during the request.
Targeted at groups of users because it's a shared environment. Data is stored in an exclusive server-based format. It performs more complex analysis of data.
DOLAP - Desktop OLAP.
Small OLAP products for local multidimensional analysis Desktop OLAP. There can be a mini multidimensional database (using Personal Express), or extraction of a datacube (using Business Objects).
Designed for low-end, single, departmental user. Data is stored in cubes on the desktop. It's like having your own spreadsheet. Since the data is local, end users dont have to worry about performance hits against the server.
ROLAP - Relational OLAP.
Designates one or several star schemas stored in relational databases. This technology permits multidimensional analysis with data stored in relational databases.
Used for large departments or groups because it supports large amounts of data and users.
HOLAP:Hybridization of OLAP, which can include any of the above.
