ABAP is a language which was initially developed for the technical users and it hosts many features. All the components are saved in a data dictionary in sap abap; listed below is a brief overview of some of the components of the dictionary:

The ABAP Dictionary is known as descriptive of the objects which are used in application development and reflects how they map appropriately to the databases in a relative manner and this is also displayed in tables or views.

There are three important aspects in ABAP, namely: structure, tables as well as views. Tables are always independently defined of the database. The remaining are all defined as well as separately activated. Once they have been activated, they are also available system-wide, which also ensures security, integrity as well as and consistency of data.

In the ABAP dictionary Tables, domains as well as the data elements all help in defining the data. Domains are used for technical definitions and tables and data elements are utilized for a more semantic definition. Fields are known as a subsection of tables and are always maintained within one; and the field in a table related to the data elements.

Data elements are known as dependent on the existence of a domain; and they also help in determining how a field is visible to the end-user, while they seem individual objects. Data elements are objects and can be reused once these have been well defined, and this could be amongst the other fields or also within the same table.
Data elements can also be descriptive regarding the technical attributes and for the meaning of the field in a table. Of a field, data elements are also accountable for the semantic definition which would also entail the field labels which are essential for display.

The domain is utilized as a centralized object, meant for describing the various technical characteristics of an attribute of a business object and this is done by describing the value range of the field; which is performed by specifying the things like the length and the external format. This specification of values, tends to confine the value range.

The main purpose is ensuring consistency in the data and for any entry of new data, it has to be verified against all the previous entries for ensuring that there is no contradiction. The fields also come under foreign keys in case a combination of fields is utilized as a primary key in another table.

SAP ABAP is known as an extremely important programming language which us presently being used by various companies like STechies.
