This famous saying in the industry is mainly used to emphasize the importance of data in information management systems. A complete software system consists of programs, data, and documents. Specifically for the information management system, it consists of the database management system DBMS, database DB and help file (DOCUMENT). In the current country, the underlying technology of the database is out of the question. It is completely occupied by MS SQLSERVER2008, MY SQL, ORACLE, SYSBASE, and IBM's DB. Most of us can only do some work on DBMS with E-text names such as OS DBMS. Application development can be said to be equivalent to secondary development.
Management means establishing and supervising the implementation of systems in terms of security, operation, allocation of operating authority, and data collection. Management is more important than technology. No matter how advanced the DBMS technology is, no matter how good the information management system is, if the management cannot keep up, and no matter how good the system is, if the system is not implemented, the powerful effect of MIS will not be exerted and it will only bring waste.
In database technology, information can be represented by a system of data, or in other words, a series of data can reflect a piece of information. A record represents many attributes of an object. Therefore, it is very important to reflect the initialization data of the information management unit and the basic data that reflects the unique attributes of many things. Compared with the technology used and daily management, the importance of data is countless times greater.
The value of the information management system MIS is reflected in the use of modern technology to quickly retrieve information (conditional query), perform statistical analysis in real time, and even provide decision-making support. Just imagine, if there are not enough data records in the information management system and it is just a gorgeous empty framework, then the value of information retrieval, statistics, analysis, decision support and other values ??cannot be discussed at all. If the accuracy, completeness, and timeliness of data records are not high, and there are too many logical errors, the results of information retrieval, statistics, analysis, and decision support will be greatly compromised in terms of meaning and value.
There is a "99 degree" theory in management. In layman's terms, it is the barrel theory or the short board effect. In short, in a database system, if there is no data or the data is not rich enough, there is no database. Data is inaccurate, untimely, and incomplete. No matter how advanced foreign database technology is used, no matter how advanced management systems are formulated, they are all constrained by the shortcomings of data. This is called "twelve points of data".
