1 Current Situation and Problems of University Data
After years of information construction, most colleges and universities have established relatively complete software underlying platforms and various information systems. In the process of its own information construction, it has optimized the business process, realized the digital information flow, and accumulated a large amount of data wealth at the same time. However, in terms of underlying data operation and maintenance and emergency response, there is a lack of a complete service system to ensure the timely processing of various data service needs. At the same time, many daily and cumbersome data exchange works also consumes a lot of valuable time and energy of school data managers.
Therefore, colleges and universities need to introduce professional data service teams to ensure the stable and safe operation of their own information systems. At the same time, through professional security consulting and implementation services, they need to gradually build a dynamic, complete, and efficient data operation and maintenance ecosystem to form a continuously perfect and self-optimizing data operation and maintenance system, so as to provide a solid foundation for ensuring the healthy development of business and enhancing core competitiveness.
At this stage, the shared data center system of many colleges and universities generally has the following problems:
1） High Original Service Cost
At present, the data storage adopted by colleges and universities generally adopts imported databases and related products, such as Oracle DB, RAC, DG, Oracle ODI, BIEE, etc. of Oracle system. The after-sales service of such imported software products is generally provided by means of remote service websites, which generally has the problem of high prices and no on-site and on-site services.
2） Slow Demand Response
Whether it is the original manufacturer of related products at the bottom or the third-party education industry integrator, although the price is relatively low, there is a problem of slow demand response for the shared data center of colleges and universities. Often after problems occur, it is difficult to guarantee the deployment of engineers and the processing time of on-site problems. The problem response cycle of one week or even one month cannot meet the business needs of colleges and universities.
In addition, in the operation and maintenance stage, the shared data center in colleges and universities will continue to generate new data integration and data application development needs. Therefore, the contradiction between the continuous derivation of needs and the inability of follow-up implementation services has become increasingly prominent.
3） Key Technical Problems Have a Long Processing Cycle and Cannot Be Solved
Because many education industry integrators are not focused on the data technology field, when dealing with complex or sudden technical service needs, the processing results become very unsatisfactory.
For example:
In the traditional processing of colleges and universities all-in-one card database, there are problems that tens of millions of pieces of data cannot be synchronized or get stuck in the synchronization process.
When the interface between the shared data center and other third-party webservice needs real-time data exchange, it often needs to be realized with the help of code development, and the goal of real-time and stability cannot be achieved.
When it is necessary to complete the data connection with Excel, it is often limited by the operating system (such as Linux) or the inherent technical requirements (such as ODBC), which affects the effect of data synchronization.
When unstructured data needs to be synchronized, the traditional data exchange technology cannot be realized.
Due to the failure to establish a complete database architecture and disaster recovery system in the initial stage, it is difficult to maintain in the later stage.
At the initial stage of business system development, developers’ lack of code writing ability led to many hard parsing problems in the database, which is the root cause of database performance problems.
However, with the explosive growth of data resources in colleges and universities, more and more technical problems will emerge, and the handling of special technical problems will become more and more frequent. Therefore, professional data service teams are also required to carry out relevant maintenance, optimization, integration, and implementation.
4) The Daily Service Work is Complex, Affecting Their Own Work Efficiency
With the continuous improvement of the business system in colleges and universities, the demand for data exchange is also increasing. To deal with the data exchange demand in colleges and universities, the information center of colleges and universities often takes pains in continuous communication and coordination, thus affecting its own work main line and reducing work efficiency.
5) The Technical Operation is Not Standardized, and the Operation and Maintenance Tracking is Not Guaranteed
As the colleges and universities shared data center involves core businesses such as data exchange and data sharing, the data security, operation security and behavior tracking of the shared database become extremely important. Due to non-standard operations, data loss, development source code loss, database load imbalance and other situations occur one after another. Therefore, there is an urgent need for a professional data service team to solve and guarantee.
6) Nonstandard Business System Development and Difficult Database Maintenance
During database development, developers of application system developers have common performance problems due to the lack of specification in SQL preparation, which leads to the degradation of database performance, and it is difficult to modify SQL in a short time. Such problems are particularly obvious in business peak periods.
