Middle

The networking database model is basically a design to correct the flaws in the hierarchical model specially when there is too much data. However, those databases have been replaced by the new database model. The most database model used nowadays is the "relational database"[eHow]. Developed by Dr. E. F. Codd who was a mathematician working in IBM. Due to the fact that he was a mathematician he developed the relational model based on "mathematical concepts"[the UK web design company] and ideas where each table in the database is connected with the rest of the tables by one or more common key. In this case, the first table would have general information for example, one column titled "patient ID", another column titled "Patient Name", a third column titled "Date of Birth". The second table would have information about specific medical information e.g. taking particular vaccinations at specific ages or if the patient has particular disease, however the common column would be "Patient ID". So the Patient ID is the common key that links all the tables together in the DNA database. This new development made it easier for the data to be accessed retrieved, inserted, updated, or deleted and caused more and people to use those databases and store information on them. ...read more.

Conclusion

Usually the database is saved in its own computer that is specialized for only saving information. That computer is stable and protected on its own, unlike a "public-facing server"[TechTarget] such as a "web server" [TechTarget] (internet). All necessary protection softwares and program patches (e.g. Firewall, Anti-Adware, Anti-Virus...etc) should be downloaded, installed and updated and all "unnecessary features" should be deleted. The database should have a hard username and a password that should be changed frequently every 48 days for example. In case the security is violated and the database is hacked, the privacy of the data will be violated thus to solve the privacy issue is to make sure that the individuals or the patients are aware that their information might be viewed by others in case something goes wrong. This can be done by giving patients forms to sign in which they state that they are fully aware that their information might be viewed by others. Thus by overcoming those issues and limitations, the broad DNA database is a good step towards using technology to improve the scientific and medical field.
