While this form may be unimportant for non-temporal data, it is certainly important when maintaining data containing temporal variables of a point-in-time or interval nature. With the advent of Data Warehousing 2.0 (DW 2.0), there is now an increased emphasis on using fully-temporalized databases in the context of data warehousing, in particular with next generation approaches such as Anchor Modeling . In this paper, we will explore the concepts of temporal data, 6NF conceptual database models, and their relationship with DW 2.0. Further, we will also evaluate Anchor Modeling as a conceptual design method in which to capture temporal data. Using these concepts, we will indicate a path forward for evaluating a possible translation of 6NF-compliant data into an eXtensible Markup Language (XML) Schema for the purpose of describing and presenting such data to disparate systems in a structured format suitable for data exchange.

  • Normalization
    Normalization Normalization is a process in which we refine the quality of the logical design. Some call it a form of evaluation or validation. Codd said normalization is a process of elimination, through which we represent the table in a preferred format. Normalization is also called “non-loss decomposition” because a table is broken into smaller components but no information is lost. Are We Normal? If all values in a table are single atomic values (this is first normal form, or 1NF) then our database is technically in “normal form” according to Codd—the “math” of set theory and predicate logic will work. However, we usually want to do more to get our DB into a preferred format. We will take our databases to at least 3rd normal form. Why Do We Normalize? 1. We want the design to be easy to understand, with clear meaning and attributes in logical groups. 2. We want to avoid anomalies (data errors created on insertion, deletion, or modification) Suppose we have the table Nurse (SSN, Name, Unit, Unit Phone) Insertion anomaly: You need to insert the unit phone number every time you enter a nurse. What if you have a new unit that does not have any assigned staff yet? You can’t create a record with a blank primary key, so you can’t just leave nurse SSN blank. You would have no place to record the unit phone number until after you hire at least 1 nurse. Deletion anomaly: If you delete the last nurse on the unit you no longer have a record of the unit phone number.

Knowles, Georgia Southern University, Statesboro, USA, [email protected] M. Pavlic, Sveuciliste Rijeka/Odjel Informatike, Rijeka, Croatia, [email protected] ABSTRACT The paper’s scope is conceptual modeling of the Data Warehouse (DW) staging area seen as a permanent system of records of interest to regulatory/auditing compliance. The context is design of enterprise data warehouses compliant with the next generation of DW architecture that is DW 2.0. We address temporal DW aspect and review relevant alternative models i.e. compliant with DW 2.0, namely the Data Vault (DV) and the Anchor Model (AM). The principal novelty is a Conceptual DV Model and its comparison with the Anchor Model. Keywords: Conceptual Data Vault, Persistent Staging Area, Data Warehouse, Anchor Model, System of Records, Staging Area Design, DW Compliance, Next Generation DW Architecture, DW 2.0 INTRODUCTION The new DW architecture 2.0 [14] is an attempt to define a standard for the next generation of Data Warehouses (DW). One of the explicit requirements in the DW 2.0 is to support changes over time (while preserving the entire history of data and its structure). A DW 2.0 staging area may be explicitly recognized as a System of Records [15] or an Enterprise DW, see [4], and [20].

  • Normalization Exercises
    DATABASE DESIGN: NORMALIZATION NOTE & EXERCISES (Up to 3NF) Tables that contain redundant data can suffer from update anomalies, which can introduce inconsistencies into a database. The rules associated with the most commonly used normal forms, namely first (1NF), second (2NF), and third (3NF). The identification of various types of update anomalies such as insertion, deletion, and modification anomalies can be found when tables that break the rules of 1NF, 2NF, and 3NF and they are likely to contain redundant data and suffer from update anomalies. Normalization is a technique for producing a set of tables with desirable properties that support the requirements of a user or company. Major aim of relational database design is to group columns into tables to minimize data redundancy and reduce file storage space required by base tables. Take a look at the following example: StdSSN StdCity StdClass OfferNo OffTerm OffYear EnrGrade CourseNo CrsDesc S1 SEATTLE JUN O1 FALL 2006 3.5 C1 DB S1 SEATTLE JUN O2 FALL 2006 3.3 C2 VB S2 BOTHELL JUN O3 SPRING 2007 3.1 C3 OO S2 BOTHELL JUN O2 FALL 2006 3.4 C2 VB The insertion anomaly: Occurs when extra data beyond the desired data must be added to the database. For example, to insert a course (CourseNo), it is necessary to know a student (StdSSN) and offering (OfferNo) because the combination of StdSSN and OfferNo is the primary key. Remember that a row cannot exist with NULL values for part of its primary key. The update anomaly: Occurs when it is necessary to change multiple rows to modify ONLY a single fact.

  • A Developer's Guide to Data Modeling for SQL Server
    Praise for A Developer’s Guide to Data Modeling for SQL Server “Eric and Joshua do an excellent job explaining the importance of data modeling and how to do it correctly. Rather than relying only on academic concepts, they use real-world ex- amples to illustrate the important concepts that many database and application develop- ers tend to ignore. The writing style is conversational and accessible to both database design novices and seasoned pros alike. Readers who are responsible for designing, imple- menting, and managing databases will benefit greatly from Joshua’s and Eric’s expertise.” —Anil Desai, Consultant, Anil Desai, Inc. “Almost every IT project involves data storage of some kind, and for most that means a relational database management system (RDBMS). This book is written for a database- centric audience (database modelers, architects, designers, developers, etc.). The authors do a great job of showing us how to take a project from its initial stages of requirements gathering all the way through to implementation. Along the way we learn how to handle some of the real-world design issues that typically surface as we go through the process. “The bottom line here is simple. This is the book you want to have just finished read- ing when your boss says ‘We have a new project I would like your help with.’” —Ronald Landers, Technical Consultant, IT Professionals, Inc. “The Data Model is the foundation of the application. I’m pleased to see additional books being written to address this critical phase. This book presents a balanced and pragmatic view with the right priorities to get your SQL server project off to a great start and a long life.” —Paul Nielsen, SQL Server MVP, SQLServerBible.com “This is a truly excellent introduction to the database design methodology that will work for both novices and advanced designers.
