2. Define OLAP Cube Systems
OLAP cube systems are a fundamental tool in the analysis of multidimensional data. These systems allow users to explore and analyze large amounts of information effectively and efficiently. The definition of OLAP cube systems is a crucial step for successful implementation and understanding by users.
To define an OLAP cube system, it is important to understand the key concepts and the underlying structure. An OLAP cube consists of dimensions and measures. The dimensions represent the characteristics of the data and the measures are the data being analyzed. It is important to identify the relevant dimensions for the analysis and clearly define the relationships between them.
In addition, hierarchies must be defined within each dimension. Hierarchies represent the higher and lower level relationships within a dimension. For example, in a time dimension you can define hierarchies such as year, quarter, month, and day. These hierarchies will be useful for performing analysis at different levels of granularity.
3. Architecture of OLAP Cube Systems
The architecture of OLAP (Online Analytical Processing) systems is based on the use of multidimensional cubes to store and analyze data. An OLAP cube is a logical structure that allows you to organize data in a hierarchical and categorized manner. These cubes represent different dimensions, such as time, product and location, and contain numerical measures that can be analyzed from different perspectives.
It consists of several key components. First, there is the OLAP engine, which is responsible for processing the queries and generating the requested results. Then there is the cube manager, who is responsible for storing and organizing the multidimensional cubes. In addition, a presentation tool is required to visualize the results intuitively.
To design a cube-based OLAP system, it is important to follow certain steps. First, the dimensions and measures relevant to the data analysis must be identified. We then proceed to create the structure of the cube, defining the necessary hierarchies and levels. The data is then loaded into the cube using specific data extraction and transformation tools. Finally, queries and reports can be generated using the presentation tool, taking advantage of the analytical capabilities of OLAP systems.
