PC\Laptop will never be dead although new platform emerge: Analysis of Microsoft Strategy

PC / laptop may be dead or it will become centre piece of interaction of all devices at home.
Now as internet of things evolve or semantic agents start searching  web for you and customize search for you.
There will more than 100 devices like fan , cooler, heater, washing machine , each room sensor etc in your home as Home computing/smart city emerges platform like Zigbee, personal area network become more visible. PC will become like server controlling/configuring/updating/debugging all these devices at home.
This is in response to this news I am writing:
that Microsoft is trying to keep PC as device of choice.
Some places where low computation and mobilty is required smartphone and tablet may take up market which they already have but still PC/laptop will have its own market as it will become Home server of choice.
At end of day you want to come back home and sink all your devices to server which is Laptop with max processing power to do it fast.

How to solve mutating table Error? Oracle PL\SQL

What is mutating table Error?

One of the scenario when mutating table errors occurs when Table A is parent to Table B and there are triggers defined on table A trigger a1 and on Table B trigger b1.
Triggers are defined in such way that before insert trigger a1 on A

Mutating table error
before insert trigger b1 on Table B. inside trigger b1 you are trying to check value in parent table if it exits parent field. While in parent Table A triggers are called before insert which having reference to Table B values. this leads to kind of race conditions causing mutating table error.
How to solve mutating table error?
While writing trigger care should be taken that parent table triggers should try to avoid update to child table otherwise mutating table error occur.
There are more scenario which would be covered in next Example you can just read many reference available on Mutating table Error.
just do a google search and read its common PL/SQL error which would face.

second option: Use after insert trigger.

Strategies For Software Services/product Companies next decade




These requirement are going to stay for next decade:Strategy-Small1Where can Software services/product firms lay emphasis for next stage of development. Or the areas which will see maximum amount of work coming in future..

Or What areas of knowledge should software companies develop manpower on:
1. Game development and Gamification:

2-7. Each of the Seven areas in development:

As you read you realize software which can take advantage of multiple processor available on the devices None of sotware present in market today is written to take advantage of this fact. It may be possible an new language may come up to take benefit of this fact of we can still use old java/C++ threads more offen or we can distribute load on server by more specific COM/ DCOM or Distributed Common Request broker Architecture CORBA to processor level at server.. We have virtual switches and VM ware or Zen virtualisation which can exploit maximum benefit from it.
8. More virtualised network stack: this I wrote 2 yrs back still valid to quote here:

private and public cloud new API will emerge: https://sandyclassic.wordpress.com/2011/10/20/infrastructure-as-service-iaas-offerings-and-tools-in-market-trends/

9. from SDLC V model to Agile and now to lean Agile ..use of six sigma to control process is just one part of mathematics being used for quality control but there would be new data model which will be tested based to mathematical modelling like probability distributions new model industry specific models would keep emerging.
like how for security project how security user stories are plugged into model

10.  BI would be Everyware:
parallelism , map reduce algorithm and cloud

Next generation Application development

The Next generation application development will not only take care of utilizing 50 or 100+ processors which will be available in you laptop or desktop or mobile but by using parallel processing available at clients
I covered 7 points last article this is part -2 of
also Next genration ERP read first: https://sandyclassic.wordpress.com/2013/09/16/new-age-enterprise-resource-planning-systems/
8. More pervasive BI eating App: Business Intelligence application development will go deeper in organisation Hierarchy
Oraganisation Hirearchyfrom more strategic level BI  and Middle management level to more pervasive  transactional processing level , and Office automation System level BI (shown in diagram as knowledge level or operational level.)

How it will affect architecture of Enterprise product Read SAP HANA
Understanding Management aspect to little contrary view but related.. there will be need for more deeper strategic Information system to make more unstructured decision making.

pervasive BI bound to eat up Application development market also fulled by in-memory products like cognos TM1, SAP HANA etc..but also changes, cross functional innovation happening at enterprise level.

As with these products no need for separate Database for datawarehouse and for operational systems. This unification of Operational data store ODS and data warehouse DW. on reporting level both Business intelligence BI and operational reporting will be accessing same database and that will be using in Memory technology.

9. Bigdata as everyone knows is Hot: more unstructured data than structured data today present for you is like open laboratory to experiment. More of it will find place in strategic management system and Management Information system.

10. Application security will be important as never before: its already there .
The intensity can be gauged from fact that changes in top 10 OWASP list is happening as never before and positions are changing in terms of top most risk ranking.

list before:


2010 A2 was Cross site Scripting XSS but 2013 at ranking to of perceived risk is Broken Authentication and session management. Changes do happen but here ranking and no of incident changing fast because momentum is fast.
11. More will continue when I find time next time….
