2.1 specific content (understanding)

Oracle is one of the largest software providers in the world, along with Microsoft and Adobe. And with the development of Oracle, he has become one of the largest providers of enterprise office platform.

Oracle, which means oracle inscription in Chinese, was translated as "oracle" and "darling of God" in ancient Greek mythology. Oracle first came to IBM as an analyst's paper on the development of relational databases.

So at this time, the founder of Oracle began to develop his own database software, and this database is our later Oracle database.

Later, Scott left Oracle to develop a set of his own database-PointBase, but this database did not get very good development. Later, after 2000, PointBase began to be promoted as BEA's workshop development strategy, but then ironically, Oracle acquired BEA, so the PointBase database basically disappeared.

In Oracle's strategy, all the developments are carried out with Microsoft as competitors, which means that all product lines of Oracle are targeted. For example, Microsoft has developed customized ERP and CRM systems (too expensive, split for sale) on Office,Oracle, the office platform launched by Microsoft.

Later, Oracle acquired Sun and acquired Java, so it completely surpassed Microsoft's. Net platform developers in terms of development language technology. However, it is a pity that Oracle lagged behind in the cloud era, and then Oracle began to vigorously promote its own cloud services. Later, the 12c version released by Oracle also supports the so-called cloud age, which is actually the beginning of the halo era.

Oracle 11g (1.7g): a stable version of Oracle 10g, which is now widely used in new projects.
