Data Element

A data element is a piece of data which is self contained and is part of a larger set of data in a particular system. Every component is vital for the system’s operations since it adds particular data that are required for the system to function appropriately, including numerical values, names, or any other type of data.

Role of Data Elements in a System

In data management, a data element is a single piece of information which is stored within a structured framework including a database or a data model. The elements can also be of different types; this can includes basic types such as intergers and strings among others to more complex such as objects and records. Nonetheless, each data element has a significant function in supporting the capability of the system in handling information, storing it and retrieving it.

For instance, in a database data elements may be specific items of information that may be stored in a table for instance, a customer’s name, address or account balance. All these data elements when integrated give the system a complete and sufficient data record to perform operations such as searching, updating and analyzing.

Data Elements and Metadata

In the context of metadata, a data element is quite specific in terms of its meaning as to the semantics of the data, that is the meaning of the data. Thus metadata is the information which describes specific data elements telling what each element is and how it should be utilized. This makes sure that the data elements are not just isolated pieces of information which can be randomly arranged, but rather, are comprehended in the context of the whole system.

Discovery of Data Elements

Recognizing and comprehending the data elements within an application or a system is a very important step in development, modification or integration of the application or system. Data elements can be identified during a survey of the systems and of the code that is in the application. This discovery approach can be done by the developers who analyze the code base in order to determine each single piece of data and its function in the given system.

On the other hand, the discovery process can also be done through application of tools like Application Discovery and Understanding (ADU). Using the application’s code, documentation, and data structures, ADU tools collect information on data elements to create a detailed inventory of the data that is present in the application. This automated fashion is especially important in large or intricate systems because it is easier and more accurate to track data elements mechanically.

Importance of Data Elements

Every data element is an important part of the whole system information architecture, which is no less than a system. The appropriateness, suitability and storage of data elements are vital in the functionality of the system. The improper management of data elements or mistakes made in the same can result in wrong processing, data loss or even system failure thus emphasizing the need to correctly recognize and manage these elements.

Conclusion

A data element is a basic piece of information that forms one element of a data structure that is necessary for the purpose of a given system. In the sense of metadata, data elements are defined and are used for supporting the semantic of the data within the system. Knowing and identifying the data elements manually or with the use of tools like Application Discovery and Understanding (ADU) is very important as it will aid in checking the proper and efficient functioning of the system. Every data element is very important since it has a specific function in the proper handling of information within the system.
