====Objinfo: new structure====
 
−
 
−
The structure of Objinfo should be changed. The original plan was that there is at most one row of Objinfo per Object. Now it is clear that this does not have all functionalities we need. Instead, there should be a possibility to add any number of actions per object. Therefore, even the name of the table should be changed to Act. The structure should be changed accordingly:
 
−
* The field id is the primary field for the table. It is NOT the Obj.id any longer.
 
−
* A new field Obj_id should be added. This is the old field id.
 
−
* End field should be removed, it is not used.
 
−
* Url should be changed to Comment, as it may contain also other info.
 
−
* The length of Comment should be 250 characters (at least).
 
−
* Begin should be replaced by When, which is the current timestamp of the row addition.
 
−
* A new field Act_id should be added.
 
−
* A new table Acttype for actions should be added. It would contain only fields id and Act, and the following rows:
 
−
*# Start the object
 
−
*# Finish the assessment
 
−
*# Add a reference
 
−
*# Add an URL
 
−
*# Peer review the object definition: accept based on the discussion
 
−
*# Peer review the object definition: reject based on the discussion
 
−
*# Peer review the object definition: accept (personal opinion)
 
−
*# Peer review the object definition: reject (personal opinion)
 
−
*# Clairvoyant test for the scope: pass
 
−
*# Clairvoyant test for the scope: fail
 
−
*# Save a run of the object.

This page is about the structure of Opasnet Base. For a general description, see Opasnet base.

Scope

Opasnet base is a storage and retrieval system for results of variable and data from studies. What is the structure of Opasnet base such that it enables the following functionalities?

  1. Storage of results of variables with uncertainties when necessary, and as multidimensional arrays when necessary.R↻
  2. Automatic retrieval of results when called from Opasnet wiki or other platforms or modelling systems.
  3. Description and handling of the dimensions that a variable may take.
  4. It is possible to protect some results and data from reading by unauthorised persons.
  5. If is possible to build user interfaces for easily entering observations into the Base.


Definition

Data

Software

Because Opasnet base will contain very large amounts of mostly numerical information, the state-of-the-art structure is a SQL database. Because of its flexibility, ease of use, and cost, MySQL is an optimal choice among SQL software. In addition to the database software, a variable transfer protocol is needed on top of that so that the results of variables can be retrieved and new results stored either automatically by a calculating software, or manually by the user. Fancy presenting software can be built on top of the database, but that is not the topic of this page.

Storage and retrieval of results of variables

The most important functionality is to store and retrieve the results of variables. Because variables may take very different forms (from a single value such as natural constant to an uncertain spatio-temporal concentration field over the whole Europe), the database must be very flexible. The basic solution is described in the variable page, and it is only briefly summarised here. The result is described as 

  P(R|x1,x2,...)

where P(R) is the probability distribution of the result and x1 and x2 are defining locations of a dimension where a particular P(R) applies. Typically locations are operationalised as discrete indices. A variable must have at least one dimension. Uncertainty about the true value of the variable is operationalised as a random sample from the probability distribution, in such a way that the samples are located along an index Sample, which is a list of integers 1,2,3...n, where n=number of samples.


Dependencies

Result

Opasnet base is a MySQL database located at http://base.opasnet.org.

Table structure

Formula structure

Now it has become clear that it is not enough to have samples of the result distributions. It must be possible to completely recalculate the result based on the information in the Opasnet Base. There are different approaches:

  • Calculate the result based on a formula that may refer to other variables called parents. This is a deterministic approach.
  • Calculate the result based on the marginal distribution and (conditional) rank correlations with parent variables. This is a probabilistic approach.

This approach requires new tables, namely Formula and Language.


--11: Do we need tables DIF and DIP like Uninet? --Jouni 21:50, 30 December 2009 (UTC)
  • DIP
    • DIP_node_id
    • DIP_parent_node_id
    • DIP_corr_coeff
    • DIP_parent_index
  • DIF
    • DIF_node_id
    • DIF_formula
    • DIF_varnames_in_formula

All tables: Overview

  • We need Ressec (Result secure) and Resinfosec (Result info secure) tables for secure information. All other tables are openly readable except these two. They have the same structure as Res and Resinfo tables, respectively.

←12: Objinfo should be renamed Act. --Jouni 12:55, 31 December 2009 (UTC)
←13: Uploads (previously "runs") should no longer be called objects. They belong to table Act. As a side effect, one upload refers to exactly one object (i.e., when uploading a full model, all object will have different upload numbers). --Jouni 12:55, 31 December 2009 (UTC)
