Open Streetmap API (embed)



View Larger Map

Here Open Street Maps is embedded via a simple i-frame – but it’s just a standard map. Not much Leaflet or Mapbox styling is possible when we use the OSM embed options. But at least you may add a marker via the OSM web page. As far as I can see the marker is made via Leaflet somehow.

Since the AUH is a behemoth building complex. But you can use the pointer in order to pinpoint an entrance or building.

ER-Diagram Symbols

Above you see the atomic building blocks of the ER-Diagram:

  • Entity
  • Attribute
  • Relation
  • Carninalities (Crow’s feet notation) one, zero-or-one, zero-or-many, one-or-many, many.

From Requrements to Deployment

Model inspired by Jukić et al.

ER-Diagram

This ER-Diagram is inspired by some of the tables in his sample database

 

Database Implementation

Here are Ben Forta’s tables in PhpMyAdmin “design viewW.

During implementation you will create the tables and structure.

Note that you have to design the data as integers, numbers, etc.:

  • cust_id = int(11)
  • cust_name = char(50)

The customers table in ER-diagram form.

Normalizing

 

In the diagram the cardinalities have to be normalized. Here are a few solutions to typical problems.

 

TIP: From ER-diagram to HTML form

Look at the attributes. Create an input for each field. Then use the INSERT keyword.
