ANNEX I
DATA FORMATS

1. Introduction

This annex will discuss, and exemplify, the data formats proposed for the computer based system of economic analysis of fish culture activities. It concerns those formats needed for the first stage of development (see section 5.1).

The author is of the opinion that the information contained in the formats described in this annex should be sufficient for the economic analysis proposed for the first stage of system development. Naturally, however, this information would be handled by the computer making use of a much larger number of matrixes than given here. Possibly a greater number might make computer usage more efficient. If so, this will become apparent as programming work progresses.

2. Standard data formats

The five types of standard data formats are listed and exemplified in this annex: Basic Formats for Economic Data (BFEDF) Farm related; Basic Formats for Economic Data NATIONAL (BFEDN); Standard Formats for Economic Information for the culture bit (SFEI-I) and Standard Formats for Economic Information for the accounting bit (SFEI-II).

2.1 Identification

The data on culture units must be identifiable. Therefore, the data formats holding this information must be identifiable. The identification of format types should not prove a difficulty. A simple alpha-numerical code of the type used in this text can be used.

It seems logical to identify the data content of formats by providing information on one or more of the following six identifiers:

• culture bit;

• enterprise bit;

• farm bit;

• accounting bit;

• period; and

• region.

The farm related data which is physical in nature will be identified by the farm bit in all cases. This is so because output will be presented, always, for ‘farm-bits’ (even if the farm bit in question is not more than a culture bit). The farm related economic data will be identified at least by the farm bit and the period. Economic data which is not farm related will be identified by the region and the period. In practice, each standard format will be identified by one or more of the above six ‘identifiers’.

2.2. Basic Formats for Physical Data (BFPD)

There are 21 formats. They are listed in Appendix I-1. However, in reality there are only 7 different formats. That is why examples of only formats 1, 2, 3, 4, 13, 14 and 19 appear in Appendix I-1. Formats 5, 6, 7, 8, 9, 10, 11, 12, 15, 16, 17, 18, 20 and 21 are identical in format to one of those exemplified, the difference appearing only in the title.

Formats 5, 6, 7 and 8 are identical to the first four but relate to the enterprise bit instead of to the farm bit. Similarly, formats 9, 10, 11 and 12 are identical to the first four but relate to the ‘culture bit’ instead of to the farm bit.

Formats 13, 15, 16 and 17 are identical, the only difference being in the titles.

Formats 14 and 18 are identical, the only difference being in the titles.

Formats 19, 20 and 21 are identical, the only difference being in the titles.

2.3 Basic Formats for Economic Data Farm Related (BFEDF)

There are 10 formats (BFEDF). They are listed in Appendix I:2.

2.4 Basic Formats for Economic Data, National (BFEDN)

These are six basic formats. They are identical in layout to formats BFEDF/5 to BFEDF/10. They appear in two sub-sets: BFEDN-I and BFEDN-II. The first sub-set will contain information on normal, market prices for the area concerned. The second set will contain policy makers' estimates of appropriate ‘shadow prices’.

2.5 Standard Formats for Economic Information (SFEI)

There are 22 formats, as listed in Appendix 1:3, comprised of two sets of 11 formats. One set refers to the ‘culture bit’; the other to the ‘accounting bit’.

In each set, formats 3, 4 and 9 are basically the same; similarly formats 5, 6, 7 and 8 differ only with respect to headings.

Thus, Appendix I:3 includes examples only of formats I/1, I/2, I/3, I/5, I/10 and I/11.

3. Stage I of programming work

In chapter 5, the content of the first stage of computer programming has been proposed. It would seem advisable to:

• programme all Basic Formats for Physical Data;

• programme all farm-related Basic Formats for Economic Data;

• programme all standard formats for economic information related to the culture unit.

It would be possible to do with less than this.

• In BFPD it is not necessary to programme the last formal type, that is the one represented in formats 19, 20 and 21.

• It is strictly essential to programme only BFED 4, 5, 6, 7 and 10, although it would be better to prepare all the standard BFED. If not, the algorithms (B) must be remade once the the other formats have been programmed.

• With regard to SFEI, it might be possible to do without formats 2 and 11.
