A typical example might be that a specific business requires a certain field length to be imposed because a current database is already in place within the business.
另一个问题在于，精确字段仅指定一个参数的最大长度，但是缓冲区需要针对组合起来的数据的最大尺寸调整大小。
Another problem is that precision fields only specify the maximum size of one parameter, but buffers need to be sized for the maximum size of all data combined instead.
例如某些表单的字段，跨越了几行，每行的长度也可能不尽相同，这使得标准的报表组件很难处理。
For instance some forms have fields that span a few rows and the length on each row can be different, which make it difficult to handle by standard reporting items.

源数据的字段规格是什么(字段名、类型、数据长度)？
What are the field specifications of the source data (field name, type, data length)?
该分析最常用于确保字段长度（对于数值型数据，则包括精度和等级）是一致的，但是也可以解决数据类型不匹配的问题。
Most commonly this looks to ensure that field lengths are consistent (or precision and scale for numerical data), but may also address issues in misaligned data types.
字段长度分析是分析当前的源系统是否能在字段长度上与目标模型映射。
The field length analysis is an analysis of whether or not current source systems can map correctly at the field length level of our target model.
