Develop a Database

Hello, This looks like an interesting project and a chance to learn something new. I do not have much knowledge about the geomagnetic field other than what I quickly read on Wikipedia. I do however have experience with databases (PostgreSQL, MongoDB) and I have managed large instances (over 1 TB of data) and sharded clusters. I have been involved with a project that required storing vehicle tracking data so I'm familiar with GPS coordinates, GIS software (QGIS, Google Earth), libraries (python-shapely, Rtree, pyproj) and platforms (Google Maps, Openstreetmap) I also have experience with writing APIs; I generally use Python and JSON over HTTP for them. I did a quick search and I also found the WMM COF for 2015 and a Python library that makes use of it. Do you have an estimate about the number of records that need to be stored and what data they should include? Thank you for your time! Best wishes, Ionut

Hi, I am 12+ years experienced Database Programmer at CMMI-5 level company. I am working on : RDBMS: Ms Access,Oracle,MySQL,MSSQL Server 7.0/2000/2008R2 and Onwards.

Let me know when we can discuss.

Hello, I'm a PostgreSQL developer with an extensive experience in geospatial data and an active interest in data science. I haven't looked into the database yet since it requires registration to download it but if you're interested in my services I could spend some time to take a closer look at the problem.

Dear I have strong experience design databases. I also develop ETL (Extract, Transform & Load) process among different engines databases. If you are interested, please contact me. Regards!

I currently work with quite a bit of database development and it would be an interesting project to hop on board.

Hi, Neil. First of all, let me tell you I'm not familiar with WMM, but I'm ready to study it and I'm sure it won't be too hard for me, as I have a good background on GPS and navigation (I'm a computer engineer and recently attended to a theoretical flight training). I have been working with PostgreSQL for more than 10 years as DBA, so you can be sure I'm used to large databases and complex queries handling, as well as query optimization and the calculations you mentioned using SQL language. By accepting me as part of your team, you can be sure of the maximum effort to deliver quality work. I'd like to know more about your project, so that I can give you a better feedback on whether I can do it or not. You can expect a straight and sincere answer from me. I'm also open to discuss the bid value, considering this may be the first of many other opportunities we'll have to work together. Hope to hear from you soon. Alex.

I can do the job. select me ASAP and get the job done. If you want to know anything else just drop a message to me.

Hello there. I’m interested in finding out more about your exact needs and the type of integration you require. Do you need a UI built for the queries, or just a view in the database that can be utilized by some other application? What database engine are you using, or would you prefer to use? My day job involves server management for a large public university and our web environments depend heavily on MySQL, MS SQL and PostgreSQL for our needs, and all have capability for this type of data. Please let me know if you have any questions about what I can offer you, and I look forward to hearing from you about this project further.

Hi, my name is Matt and I your project is interesting - and I could help you. I understand the big picture yet I am asking if you will have the same fields e.g. measured data values as in the calculator you have provided a link. NOAA has created mobile apps too so looks like WMM data can be saved to a small database (as mobile apps are not that big, 4 megabytes). At this moment I suggest using a PostgreSQL database (and not those new "NoSQL" databases without solid operations that ensure database stability etc e.g. MongoDB). Though I would like to know how many devices will submit data (hardly believe that is only one) and if there are any variable length measured parameters - if for example MySQL database would be used the performance will be really bad without all fixed length data fields over 1 million of records. Reverse lookup could be done entirely within a database using a stored procedure (precompiled query that expects parameters). So checking a WMM best match would basically be calling a stored procedure with measured data as parameters and returning best match from the WMM table in the database. Querying a database using whatever scripting or programming language would be then much easier to implement, taking one row in measured data (or just came in parameters) to call a stored procedure with it and returning longitude and lattitude (or an error). OK, will read your answers in next 7 hours due to time difference. Looking forward to your reply, Matt

I have good experience in implementing new database. Please get in touch for further discussions
