Relational databases are the predominant method for storing repetitive data in computers because they allow efficient and flexible storage of that data. While medical directors and underwriters are more likely to use a spreadsheet than a database program to analyze their business, the data they wish to study are often stored in corporate databases. Or the data may be complex enough to require being keyed into or downloaded into a personal computer (PC) database program for storage, even if the data are then output to a spread-sheet for numerical analysis. In many circumstances, one can benefit from an understanding of efficient database design. After a brief overview, the reader is led step-by-step through a practical explanation of database design, from a flat file to a relational model.
关系数据库是在计算机中存储重复数据的主要方法，因为它们允许对这些数据进行高效且灵活的存储。虽然医疗主管和保险承销商更倾向于使用电子表格而非数据库程序来分析业务，但他们希望研究的数据通常存储在公司数据库中。或者，即使数据随后会输出到电子表格进行数值分析，这些数据可能过于复杂，需要键入或下载到个人计算机（PC）数据库程序中进行存储。在许多情况下，了解高效的数据库设计会有所帮助。在简要概述之后，读者将逐步深入了解从平面文件到关系模型的数据库设计实际讲解。
