Oracle Data Warehousing in Kuwait environment includes an extraction, modification, transportation and loading solution, client analysis tools, an online analytical processing (OLAP) engine and other applications that handle the process of gathering data and delivering it to business users.
The EDW (Enterprise Data Warehouse), built upon a relational database, continues to be the primary analytic database for storing a companies core data: financial records, customer data, point-of-sale data and so forth.
Information systems need to use all the sources of data and allow enterprises to analyze and extract business value from them. Oracle data warehousing best practices make sure that your Oracle system will leverage the full capabilities of the Oracle database.
Oracle Data Warehousing in Kuwait Models
1. The Logical Model
There are two classic models used for data warehouse, Third Normal Form (3NF) and dimensional or Star (Snowflake) Schema.
Third Normal Form (3NF) is a classical relational database modelling technique that minimizes data redundancy through normalization.
By definition, 3NF preserves a detailed record of each transaction without any data redundancy and allows for rich encoding of attributes and all relationships between data elements. Users typically need a proper understanding of the data in order to navigate the more elaborate structures reliably. A 3NF data model is commonly used in the Foundation Data Layer.
2. The Physical Model
The transition from the logical to the physical model is influenced by non-functional requirements: data integrity requirements may demand the use of certain constraints, primary keys and foreign keys.
Scalability and response time requirements will influence the use of particular optimizations such as data partitioning, pre-built aggregations and indexes. Oracle Database 12c and Engineered Systems provide features and developments that are all intended to operate transparently with respect to the Information Interpretation component.
This offers great flexibility such that the physical model can be optimized and evolved without any requirement to make changes to the applications that interact with the database. The Oracle database provides optimizations that can:
- Simplify the overall physical implementation.
- Improve scalability and query concurrency.
- Reduce the risk of keeping pace with change and reduce the need to get everything right the first time.
Data warehousing environments require high performance interconnects between database servers and the storage infrastructure because queries and transformations are likely to read and write large volumes of data.
Enterprise Data Warehouses require a large amount of storage so it is especially important to ensure that manageability and scalability is kept as simple as possible. For more information on Oracle Data Warehousing in Kuwait, please contact us.
