From getting started with Informix to developing a J2EE system based on Informix, it will be 7-8 months. Now I feel not proficient. At least I have passed the entry stage, it is okay to handle general system installation (Win/Linux), data import and export, so-called garbled issues, JDBC application development, process function writing, and so on. In retrospect, obtaining a media set and deploying an environment is indeed the most basic requirement.
Generally, the sources of Informix are summarized as follows:
1. Purchase CDs and find an acquaintance to copy them. We will not start them here.
2. online download. Generally, we can download the development or trial version from the IBM website. It is sufficient for individual learning, but sometimes we need some old versions, such as ids9.4, or the full version.
You can search for chinaunix or Google it. In this articleArticleYou can find the latest IDs version:Http://bbs2.chinaunix.net/thread-1321105-1-1.html
You can check it out for yourself. For ids9.4, you can search for it on some FTP websites or download it here:
