Validasi data dengan menggunakan objek lookup pada borland delphi 7.0

TL;DR

This paper discusses data validation using lookup objects in Borland Delphi 7.0, demonstrating how to implement and validate relational data input through specific design steps and objects.

Contribution

It introduces a practical five-step method for implementing lookup data validation in Delphi 7.0, including relational schemes and object configurations.

Findings

Lookup objects are valid for data validation

Delphi lookup objects support various relationship types

The method enhances data accuracy in applications

Abstract

Developing an application with some tables must concern the validation of input (specially in Table Child). In order to maximize the accuracy and data input validation. Its called lookup (took data from other dataset). There are two ways to look up data from Table Parent: 1) Using Objects (DBLookupComboBox and DBookupListBox), or 2) Arranging the properties of data types fields (shown by using DBGrid). In this article is using Borland Delphi software (Inprise product). The method is offered using 5 (five) practise steps: 1) Relational Database Scheme, 2) Form Design, 3) Object DatabasesRelationships Scheme, 4) Properties and Field Type Arrangement, and 5) Procedures. The result of this paper are: 1) The relationship that using lookup objects are valid, and 2) Delphi Lookup Objects can be used for 1-1, 1-N, and M-N relationship.
