Database design

Introduction The aim of this document is to give an overview of the design for the Remodece database. The database is composed of 13 tables, each containing a subset of data, that are linked together using specific fields. This document will list the table and the fields in order to understand how to use it.

1 – The set of tables composing the database. All the Remodece database is actually contained in one file : Remodece.mdb. This file, for development reasons was created using Microsoft Access software (V2000 or above). The file contains 13 tables, each one containing a data subset. This multi-table structure permits to limit the size of the global database, to speed up the searches and to simplify the importation of new data. The 13 tables are split in 4 categories :

T_Project and T_Country contain the data for the projects’ descriptions (by project we mean a measurement or survey campaign),

T_Household and T_InhabitantType contain the data for the households’ descriptions (by household we mean the houses and apartments in which the measurements or survey were done),

T_Appliance, T_AppList and T_AppFamily contain the data for the appliances descriptions (by appliance we mean the uses in the households),

T_DataList, T_AnnCon, T_MonthCon, T_LoadCurve, T_MonthLoadCurve and T_StandBy contain the aggregated values calculated for each appliance or use.

Figure 1 gives you an overview of the different tables.

2 – Field definition for the database tables. Each table contains a subset of the data needed to extract the relevant aggregated data from the database. Certain data has to be shared between all the tables in order to construct a coherent set of data (Project_ID, Household_ID and Appliance_ID are the most important) : 2.1 T_Project table

Fields Desc Value Project_ID Project Identifier 100xxxx (x=0001->9999) Project_Type Measurement campaign / Survey campaign / … Project_Name Project_Start_Date Start date of the project dd/mm/yyyy Project_Stop_Date End date of the project dd/mm/yyyy Project_Involved_Country Country_ID See T_CountryTable

(in this table, one line per country if there are more than one country involved in a project)

3 – Table dependences. Figure 2 shows the dependences existing between the different tables. This dependences are possible by duplicating certain fields between the tables :

Project_ID : unique identifier defining a specific campaign. Household_ID : unique identifier defining a household. Appliance_ID : unique identifier defining a specific appliance or use.

This 3 identifiers, present in all the aggregated data tables, are used to search and retrieve

specific results.
