1.1 How is LANSA used?

LANSA is normally used in the following way:

• Optionally, a logical model of the information that you need to handle is defined and refined, until it represents a fair and accurate representation of your data requirements. This logical model may then be converted into a set of fields and files that represent a physical implementation of it.

• Fields, files and processes are set up (or have been created automatically from a logical model) to store and process the information your company or organization needs.

• These are then used to input, store, maintain and retrieve computerized company or organization records. The level of knowledge required to use LANSA varies according to which task is being performed:

• To set up a logical data model you will require specialized data modeling skills and an ability to think in abstract and pure terms about the type of information that is being processed.

• To set up fields, files and processes you will require a sound knowledge of most of the components of LANSA (except for logical data modeling) and some experience in data processing at the programming level.

• To use LANSA to maintain company records you will need very little knowledge of LANSA. The main skills required relate to more general data processing requirements such as keyboard skills, a general understanding of computer systems and a knowledge of the organization's own business applications. The attainment of these skills is beyond the scope of this guide.
