Problem Statement\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhen queries already come out confidently, the need to care about data integrity appears. Many materials only mention constraints but do not show them in practice. It is difficult to understand how to properly protect a structure from incorrect records. Examples often remain theoretical. Because of this, creating reliable schemas requires extra attempts and checks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2. Solution\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOrigin Pack gathers modules dedicated to building stable data structures. Explanations go from simple constraints to comprehensive integrity rules. Each module contains practical exercises on creating and testing protected schemas. You see how different types of constraints work in real examples. The materials help form reliable foundations for further work.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3.
