DATA BASES CRITERIA
1. Definition of information levels – compromise between tipification (key-words indexation) and transcription of integral texts or summaries. 2. Definition of the main tables: they should reflect the research grid of Hisportos: Geomorphologic conditionalisms/ Seaports interventions/ Central and local policies/ Entities and persons involved. 3. 3. Definition of key-words: indexing specialized languages, specific to each knowledge area. Technical glossaries of hydraulic engineering and geo-morphological concepts (tables Geomorphologic Phenomena and Technologies)
DATA BASE STRUCTURE
![](img/bd_en.gif)
Data base was built in the assumption that all data are supposed to be linked in every field according criteria of interconnectivity.
A. MAIN TABLES
1. CONDICIONALISMS – Data on geomorphologic, climatic and antropic conditionalisms of seaport interventions. 2. INTERVENTIONS – Data on all kinds of harbour construction or intervention, namely technical operations linked to polices condicionalisms, geomorphology and human agents. 3. POLICES – Data on central and/or local polices regarding seaports interventions. 4. MAPS – Technical description of historic cartography
B. SECONDARY TABLES
1. GEOMORPHOLOGIC PHENOMENA and TECNOLOGIES. Meta-information: technical glossaries. 2. PERSONS and ENTITIES. – Biographic and institutional information
C. REFERENCE TABLES
1. SOURCES 2. BIBLIOGRAPHY
