About the SW0x_Project Database

Introduction to the databases

clip0012Note!
A project database can hold any number of projects. Each project is uniquely identified by a ProjectID. The ProjectID is found in every table of the Project database.

Project Info
The information found in the Project Info window of ShipWeight can be found in the SHIP-table. This includes Name, Owner, Main type, Sub type, Build year, Frame spacing etc.

Weight, Center of Gravity and Extension
Information of Weight, Center of Gravity and Extension for each weight item can be found in the ITEMS-table.

The ITEMS-table contains 123 columns/fields. These are:

 

WgtGrp

The name of the weight-group the weight-item belongs to.

ItemNo

An id-number for the weight-item (unique within the weight group).

Description

Name of the weight-item.

RegUser

Name of the user who created the weight-item.

RegDate

Date of registration.

UniqueNo

An integer to uniquely identify each weight item. The UniqueNo field is automatically assigned.

The total weight and CoG for each weight-group is available in the SHIP_POST-table. The SHIP_POST-table contains five fields. The three most important are:

ProjectID

ID to uniquely identify each project in the database.

sPostID

The name of the weight-group, e.g. LW

sType

Type of information. A = Aft, F = Fore, L = LCG, V = VCG, T = TCG, W = Weight, P=port side (TCG_min), S=starboard (TCG_max), B=bottom (VCG_min), U=up (VCG_max)

fValue

Value. Records of type V, L, T, P, S, A, F, B and U are given in meters, while records of type W is given in tons.

 

 

Parameters

Various parameters, such as lengths, areas, volumes etc. can be found in three tables: SHIP_FATT (float parameters), SHIP_IATT (integer parameters) and SHIP_TATT (text parameters).

The SHIP_FATT-table includes two columns/fields:

ProjectID

ID to uniquely identify each project in the database.

sFAttID

ID of the parameter

fFAttValue


Value of the parameter.

Likewise the SHIP_IATT and SHIP_TATT include a field for ID and a field for value.

The full name of the parameter can be found in the WeightDB database (see next page).

The parameters found in the Main Project Parameters window are:

lm
