If you publish anything, watch out for the Oracle licensing no-nos. Specifically, I believe they disallow certain comparisons. I believe performance is one of them. > Why most enterprises prefer Oracle than Postgres even though it is > free and has a decent enough user community. Many reasons, some legit, some not. I expect a Greg or two will seriously add to and correct this list, but: 1. Oracle was "first", and has vendor lock-in momentum. 2. Oracle is still the "de facto" in terms of speed/performance/concurrency (but that gap is closing fast) 3. Oracle has application lock-in as well. There've more than a few threads on this list regarding which applications. 4. Oracle is company-backed, so there is ostensibly "someone to blame" or sue if something goes wrong. Don't underestimate the managerial "need" for blame. 5. Influencing individuals within a company may prefer it *because* it's expensive, as it helps "justify" their higher salary. 6. Mucho better advertising to the right people. Much harder for an open source project to fund advertising to the same level. 7. Though I don't personally buy it, I have heard others complain loudly that there is no print-version of Postgres documentation. There's a starting list.
