Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

5. SIEPON’s QoS Mandate
Address the previously stated
problem: create a comprehensive and
flexible QoS architecture using
EPON transport that simultaneously
enables vendor interoperability.
This starts with defining service
parameters we can use as metrics to
ensure the service requirements (and
operator SLAs) are met:
CIR/CBS
PIR/PBS Throughput
parameters
EIR/EBS
Frame Delay (FD)
Frame Delay Variation (FDV)

“Best Effort Traffic”
Typically used in high bandwidth systems
with small numbers of users
(b) Priority‐first
Improves quality of higher priority traffic,
but cannot prevent starvation
Typically used in bandwidth‐limited
systems with large numbers of users
(c) Strict Priority
Improves quality of the highest priority
traffic
Used only when this highest priority
traffic must be ensured at all costs

9. Final Thoughts
Everyone wants everything!
QoS architecture must be flexible
SIEPON introduces ESPs and defines service parameters to
control QoS portions of ESPs
Flexibility of ESP allows for proper treatment of service for
different user types
Flexibility of QSD allows for proper treatment of service for
different service types
Everyone gets everything!
