Sybase最困难的时光已经过去,市场占有率未来会渐渐增大。因为有了SAP作为后盾,会投入更多资金和人力到开发和市场上。象以前通过ISUG提出的compression, database shrink, online data reorg (not index reorg) etc,一直未能落实。现在15.7已基本实现。等SAP将HANA成功植入ASE,一套数据库,一个license,就实现OLTP, DW and real-time Analytics.再加大宣传攻势,还是很有希望的。
SAP running on Oracle, for instance, will require one license for the transactional database, a separate license for the data warehouse database, and a third if the customer opts for Oracle Exalytics. Transactional data is copied into the data warehouse, and if it's needed quickly, a third copy is created in Exalytics. Each copy creates more storage, processing, and power demands. |
