Five-minute crazy talk about Oracle databases

Oracle Database problems are often encountered when learning Oracle databases. Here we will introduce solutions to Oracle Database problems. Oracle databases are fully based on the JAVA architecture, so they are more advanced than SAP? Since Oracle is more closely integrated with the underlying Oracle database platform, is it more efficient to run?

The above two points seem unrelated, but I put them together because I think they are funny. They are all like red flags and red flags!

It is undeniable that JAVA is an excellent language with good compatibility and versatility. But Does Oracle database use it to build a system mean that it can do its best to avoid its disadvantages? I don't think so.

The first is the issue of execution efficiency. As a large IT system like ERP, no one can turn a blind eye to execution efficiency. The versatility and compatibility of a piece of code are even stronger. I don't think it would be useful if I haven't finished running for half a day. I think that's why SAP claims that the complex business processes at the core of the system will still run on the ABAP language in the future. As a tested Language for business process management, ABAP has gained worldwide recognition for its performance.

In addition, SAP has not yet seen the advantages of JAVA. Now SAP's newest NetWeaver platform can support both the ABAP and JAVA environments, in addition, all interfaces related to the SAP system and external interfaces are completely completed by JAVA programs. In this way, both the advantages of JAVA and the efficiency of system operation are ensured. I have to mention that SAP has made great efforts to increase its investment in JAVA in recent years. Not long ago, it became the third company in the world except SUN and SUN, a joint venture specializing in J2EE ), in fact, SUN is the first company that officially supports the latest Java EE 5 version of J2EE.

In addition, Oracle ERP + Oracle DB must be easy to implement? I don't think so either.

I certainly believe that, as a family member, the Oracle database team may work harder with its own family members. But even if the customer chooses this bundling Method for ERP, he can ensure that other systems like CRM, SCM, SRM ...... Do I also use Oralce + Oracle? Even if the customer is Oracle's super Fans and uses Oracle from the beginning to the end, can he ensure that the upstream and downstream vendors he communicates with use Oracle for System Interconnection?

Interconnection is the trend of the times, and SAP has seen this point before it has been put down and admitted that the customer's system cannot completely adopt SAP, in the future, more important considerations should be integration and composite applications between different systems. However, Oracle is still plausible and contrary to their own open nature. Such behavior ...... It makes me feel ashamed ......
