First, give conclusions that can be used for decision-making
The risk of changing SQLs in the natural language includes error in field understanding, error connection, leak filtering, overloading, full-table scanning and malicious input. The control focus is not to make the hint more rigorous, but to reduce the semantic and implementation space that the model can choose. User questions are first mapped to approved indicators, dimensions and data sets, searching for gateways to apply identity privileges, SQL resolution, read-only limits, cost budgets and overtime. High-risk queries can generate previews only or be confirmed by data personnel. Answers should show the calibre, time and filter conditions that enable users to detect problems.
What conditions need to be identified before judgement is made?
The same question may have different answers under different business, data and project phases. It is suggested that the following conditions be checked and that the common findings on the web be incorporated into their own projects.
Suggested order of advance
First, we'll be clear about the target and the border.
Creates controlled semantic layers and read-only data sets.
Validation Key Dependence
The results are SQL resolution, filtering of rights, resource constraints and auditing.
Development of assessable outcomes
Tested with cross-cutting and large-scale search samples.
Make sure you decide the next step with the real results.
Checking failed, slow-searching and irregular access after going online.
How do you understand it in the actual business?
When asked by the regional manager for a detailed list of clients nationwide, the system returns only to the authorized area by identification; if the request contains sensitive fields, the request is not authorized. The query is converted to a pre-aggregation indicator when the scanning budget is exceeded or the time frame is reduced.
The easiest pit to step on.
Do all queries using the shared administrator database account
Hide fields only on the page and not filter them on the data layer
No decomposition, no time limit for direct execution after model generation of SQL
How should we end up receiving and confirming?
The log should be able to locate the user, problem, query and result status of the organization, column and sensitive fields, using different job accounts and covering SQL injection, tip injection, super-high query, error connection, time overtime and repeat requests.
When preparing to communicate with suppliers or internal teams, it is recommended that current processes, representative samples, existing systems, planning time and budget levels be brought. First, the unknown items are clearly marked, and then the decision is made to use diagnostics, PoC, fixed-range projects or ongoing research and development, which is usually more reliable than a direct demand for a price and duration without borders.
