MIS

Advantages of Data Warehouses

- Organized by dimension or subject: Data are organized by subject. This arrangement is different from transactional systems where data are organized by business process, such as order entry, inventory control or accounts receivable. This is beneficial because it allows it to remain organized and easily accessible to businesses and allows them to make informed decisions. - Using online analytical processing: Business transactions are processed online as soon as they happen. This allows for speed and efficiency which is critical to internet-based business operations. - Integrated: Data collected from multiple sources are organized by subject to remain easily accessible and easy to understand and interpret. This allows businesses to turn them into strategies easier. - Nonvolatile: No one can change or update the data. This allows for unbiasedness in the data and a sure-fire way to make sure that no one is tampering with the data so it is all true.

Explicit knowledge vs Tactical knowledge

Explicit knowledge deals with more technical, objective and rational knowledge. a few examples are procedural guidelines, policies, reports, guidelines and the IT infrastructure. It is knowledge that can be documented in a form that can be distributed to others or turned into a strategy. Tactic knowledge is a cumulative store of subjective or experiential learning. It is never usually recorded and it is super personal to the salesperson or employee. Examples include an organization's insights, experiences, expertise and trade secrets. It also includes organizational culture. It is generally imprecise and costly to transfer.
