  • The Design of Multidimensional Data Model Using Principles of the Anchor Data Modeling: an Assessment of Experimental Approach Based on Query Execution Performance
    WSEAS TRANSACTIONS on COMPUTERS Radek Němec, František Zapletal The Design of Multidimensional Data Model Using Principles of the Anchor Data Modeling: An Assessment of Experimental Approach Based on Query Execution Performance RADEK NĚMEC, FRANTIŠEK ZAPLETAL Department of Systems Engineering Faculty of Economics, VŠB - Technical University of Ostrava Sokolská třída 33, 701 21 Ostrava CZECH REPUBLIC [email protected], [email protected] Abstract: - The decision making processes need to reflect changes in the business world in a multidimensional way. This includes also similar way of viewing the data for carrying out key decisions that ensure competitiveness of the business. In this paper we focus on the Business Intelligence system as a main toolset that helps in carrying out complex decisions and which requires multidimensional view of data for this purpose. We propose a novel experimental approach to the design a multidimensional data model that uses principles of the anchor modeling technique. The proposed approach is expected to bring several benefits like better query execution performance, better support for temporal querying and several others. We provide assessment of this approach mainly from the query execution performance perspective in this paper. The emphasis is placed on the assessment of this technique as a potential innovative approach for the field of the data warehousing with some implicit principles that could make the process of the design, implementation and maintenance of the data warehouse more effective. The query performance testing was performed in the row-oriented database environment using a sample of 10 star queries executed in the environment of 10 sample multidimensional data models.

    Chapter 7 Multi Dimensional Data Modeling Fundamentals of Business Analytics” Content of this presentation has been taken from Book “Fundamentals of Business Analytics” RN Prasad and Seema Acharya Published by Wiley India Pvt. Ltd. and it will always be the copyright of the authors of the book and publisher only. Basis • You are already familiar with the concepts relating to basics of RDBMS, OLTP, and OLAP, role of ERP in the enterprise as well as “enterprise production environment” for IT deployment. In the previous lectures, you have been explained the concepts - Types of Digital Data, Introduction to OLTP and OLAP, Business Intelligence Basics, and Data Integration . With this background, now its time to move ahead to think about “how data is modelled”. • Just like a circuit diagram is to an electrical engineer, • an assembly diagram is to a mechanical Engineer, and • a blueprint of a building is to a civil engineer • So is the data models/data diagrams for a data architect. • But is “data modelling” only the responsibility of a data architect? The answer is Business Intelligence (BI) application developer today is involved in designing, developing, deploying, supporting, and optimizing storage in the form of data warehouse/data marts. • To be able to play his/her role efficiently, the BI application developer relies heavily on data models/data diagrams to understand the schema structure, the data, the relationships between data, etc. In this lecture, we will learn • About basics of data modelling • How to go about designing a data model at the conceptual and logical levels? • Pros and Cons of the popular modelling techniques such as ER modelling and dimensional modelling Case Study – “TenToTen Retail Stores” • A new range of cosmetic products has been introduced by a leading brand, which TenToTen wants to sell through its various outlets.

Ad hoc queries are difficult to construct for end-users or must go through database “gurus.” 2. Even standard reports require considerable effort and detail knowledge of the database. 3. Data is not integrated or is inconsistent across sources. 4. Changes in data values or in data sources cannot be handled gracefully. 5. The structure of the data does not mirror business processes or business rules. 6. The data model limits which BI tools can be used. 7. There is no system for maintaining change history or collecting metadata. 8. Disk space is wasted on redundant values. 9. Users who might benefit from the data don’t use it. 10.Maintenance is tedious and ad hoc. 2 Advantages of Dimensional Data Modeling Part 1 3 Part 1 - Data Model Overview •What is data modeling and why is it important? •Three common data models: de-normalized (SAS data sets) normalized dimensional model •Benefits of the dimensional model 4 What is data modeling? • The generalized logical relationship among tables • Usually reflected in the physical structure of the tables • Not tied to any particular product or DBMS • A critical design consideration 5 Why is data modeling important? •Allows you to optimize performance •Allows you to minimize costs •Facilitates system documentation and maintenance • The dimensional data model is the foundation of a well designed data mart or data warehouse 6 Common data models Three general data models we will review: De-normalized Expected by many SAS procedures Normalized Often used in transaction based systems such as order entry Dimensional Often used in data warehouse systems and systems subject to ad hoc queries.

As time goes by, these organizations produce a lot of data related to their business, but often these data are not integrated, been stored within one or more platforms. Thus, they are hardly used for decision-making processes, though they could be a valuable aiding resource. A central repository is needed; nevertheless, traditional databases are not designed to review, manage and store historical/strategic information, but deal with ever changing operational data, to support “daily transactions”. 3/80 Andrea Brunello Data Warehousing What is Data Warehousing? Data warehousing is a technique for collecting and managing data from different sources to provide meaningful business insights. It is a blend of components and processes which allows the strategic use of data: • Electronic storage of a large amount of information which is designed for query and analysis instead of transaction processing • Process of transforming data into information and making it available to users in a timely manner to make a difference 4/80 Andrea Brunello Data Warehousing Why Data Warehousing? A 3NF-designed database for an inventory system has many tables related to each other through foreign keys. A report on monthly sales information may include many joined conditions.

However, unlike a star schema, a dimension table in a snowflake schema is divided out into more than one table, and placed in relation to the center of the snowflake by cardinality. Now comes a major question that a developer has to face before starting to design a data warehouse. Difference Between Star and Snowflake Schema. Star schema is the base to design a star cluster schema and few essential dimension tables from the star schema are snowflaked and this, in turn, forms a more stable schema structure.

    Information Technology Policy Introduction to Data Warehousing ITP Number Effective Date GEN-INF004A November 7, 2006 Category Supersedes Information None Contact Scheduled Review [email protected] May 2022 1. Introduction Data Warehousing: Data Warehousing systems have reached a new level of maturity as both an IT discipline and a technology. 2. Main Document Content: Data Warehouse systems assist government organizations with improved business performance by leveraging information about citizens, business partners, and internal government operations. This is done by: • Extracting data from many sources, e.g., application databases, various local and federal government repositories, and/or external agency partners. • Centralizing, organizing, and standardizing information in repositories such as Data Warehouses and Data Marts. This includes cleansing, appending, and integrating additional data. • Providing analytical tools that allow a broad range of business and technical specialists to run queries against the data to uncover patterns and diagnose problems. Extract, Transform and Load (ETL) Data integration technology is generally used to extract transactional data from internal and external source applications to build the Data Warehouse. This process is referred to as ETL (Extract, Transform, Load). Data is extracted from its source application or repository, transformed to a format needed by a Data Warehouse, and loaded into a Data Warehouse. Data integration technology works together with technologies like Enterprise Information Integration (EII), database replication, Web Services, and Enterprise Application Integration (EAI) to bridge proprietary and incompatible data formats and application protocols. Data Warehouses and Data Marts A Data Warehouse, or Data Mart, stores tactical or historical information in a relational database allowing users to extract and assemble specific data elements from a complete dataset to perform analytical functions.
