Why Nokia is coming back

Posted: October 3, 2012 in Big time

I remeber it clearly, I was a pioneer. In the ’90 I use to have a cellphone and that was BIG (not kidding).

Around the end of that decade the phones where contacts, call and sms… and that’s it. My motorola was great and i loved it, reception when no other phone could and a normal size… but then nokia arrived and the T9 was the new heaven of texting.

A lot has changed and now my phone has a microprocessor faster than my pc and a camera better than ever… before the launch of the first iPhone I invested in Apple and seriously that was my best bet in a while.

So, after seen iPhone5 and Galaxy S3, I am here to state that the only real competitor for iPhone will be the Nokia Lumia 920 (http://www.nokia.com/global/products/phone/lumia920/).

I am buying NOK stocks really soon and I tell you why:

  1. wireless battery charging is just amazing;
  2. the touchscreen work also if you have gloves or a pen;
  3. augmented reality in the PureView camera tells you what you need to know about everything around you;
  4. It runs Windows and the brand new “store” will grow really fast since Microsoft development platforms are the top of the line and the easies to jump-in (we’ll see about the APIs).

I think these points are enough to define the new Lumia the next big thing.

Let me know what do you think… be back on something more “architectural” soon.

Why Stored Procedures? It’s true that SP do not allow full flexibility on the coding aspect, but it’s also true that enterprise systems are sophisticated machines that requires fine tuning and extreme security… and this is why the SP are so important.

From a developer point of view, I always see a sad faces when I “force” the use of stored procedures and sometimes, believe it o not, also from the DBAs…
Now, I want to set the target on Oracle and SqlServer and leave outside of this discussion MySQL and DB2: MySQL because when you’re talking enterprise it’s better to use commercial products (especially on the DB)… and DB2 because the implementation of IBM SP sounded always strange to me (in DB2 mainframes, apparently, the bigger and complex the SP, the better… and external access from outside the IBM sphere environment is always really slow).

In general, PROs of the SP:

  • high performance;
  • direct DBA tuning (if every access to the DB is manageable from the DBAs, the tuning is in the DBA hands as well);
  • total execution plan caching;
  • you add a layer of authentication and data validation;

and the CONs:

  • “someone” has to write them;
  • there is DBA time spent on something “developer driven”.

I had been a DBA and also a developer and I can tell you that the best place to put the “development” of the SP is in the DBAs hands… but with a custom SP code-builder.

Normally 90% of the code has the same functionality: GET to show a grid, SET to insert/update/delete values. Every time I work on this topic I build a TABLE-based SP builder which, based on the structure of the table (or view) creates the following SP:

  1. Insert, getting all fields i input;
  2. Update, getting all fields i input and checking with ISNULL if the update value is required or not and using as where always the PK;
  3. Delete, using as where always the PK;
  4. Select, using as where always the PK.

In addition to these normally are used a couple of other SELECT with different where condition. We’ll talk about the dynamic TOP and ORDER BY clause in the future, since normally we use a good amount of them.

Clearly also the calling of these stored procedures must be created from code-builders, so we can build a nice structured code, without double-coding and without add any time-consuming error.

I’ll be soon more detailed about these codebuilders, if you want you can write me and i can send you some example to speed your “perfect system” building.
