Data Warehousing - Future Aspects


Following are the future aspects of data warehousing.

  • As we have seen that the size of the open database has grown approximately double its magnitude in the last few years, it shows the significant value that it contains.

  • As the size of the databases grow, the estimates of what constitutes a very large database continues to grow.

  • The hardware and software that are available today do not allow to keep a large amount of data online. For example, a Telco call record requires 10TB of data to be kept online, which is just a size of one month’s record. If it requires to keep records of sales, marketing customer, employees, etc., then the size will be more than 100 TB.

  • The record contains textual information and some multimedia data. Multimedia data cannot be easily manipulated as text data. Searching the multimedia data is not an easy task, whereas textual information can be retrieved by the relational software available today.

  • Apart from size planning, it is complex to build and run data warehouse systems that are ever increasing in size. As the number of users increases, the size of the data warehouse also increases. These users will also require to access the system.

  • With the growth of the Internet, there is a requirement of users to access data online.

Hence the future shape of data warehouse will be very different from what is being created today.
