REP005 Creating Files

REP005 - Creating Files

A LANSA file may also be referred to as a database table. Fields are added to the file to define the record format (key columns and columns). A LANSA field can also be described as a database column. Once a file is compiled, the records in it can be retrieved, added, updated and deleted.

Objectives

To create two file definitions. You will create a Department Table and an Employee Table. These tables are similar to the ones used in the shipped DirectX Examples Windows application.

To review the database file attributes which can be defined in the LANSA Repository.

The file definitions will be as follows:

Department File iiiDepartments	Employee File iiiEmployees
iiiDeptCode*	iiiEmployNumber*
iiiDeptDescription	iiiDeptCode
	iiiSurname
	iiiGivenName
	iiiSalary
	iiiStartDate
	iiiEmployNotes

* indicates the fields used as the file key

Note: Files can be created manually or by copying an existing file definition in the LANSA Repository. In this lesson, you will manually create the file definitions so that you can see all the steps involved. If you copy an existing LANSA file definition, the fields, rules, and all other related database information about the file can be copied.

To achieve these objectives you will complete the following:

Step 1. Create File Definition

Step 2. Compile the File

Step 3. Create Department Maintenance Form

Step 4. Execute Department Maintenance Form

Step 5. Create the Employee File

Step 6. Create Employee Maintenance Form

Step 7. Execute Employee Maintenance Form

Step 8. Database Attributes
