Intermediate Database Systems Engineer Knowledge Map
A Chinese-language PDF map for data models, database design, SQL, transactions, indexes, backup and operations review.
What this knowledge map covers
This Chinese-language PDF connects database systems engineering topics into one review path: data models, schema design, SQL, transactions, indexes, execution behavior, backup and operations. It is aimed at learners preparing for an intermediate IT certification or consolidating database fundamentals through small repeatable examples.
The English page is a searchable summary and file guide. The source document remains in Chinese, and product-specific SQL behavior, exam scope and terminology should be checked against the current study requirements.
A scenario-based review path
Begin with row grain, keys and dependencies, then use a small dataset to test queries and transaction boundaries. Finish by comparing index choices, execution plans, backup types and recovery objectives under explicit assumptions.
File and scope note
The indexed file is a 104.18 KB PDF. Database products differ in types, functions, isolation behavior and plans, so retain the product and version used for each exercise. Content review date: 2026-08-23.

Database systems engineer study guide
Use the Chinese knowledge map to connect data modeling, SQL, transactions, performance and recovery through one small reproducible dataset.
Before you start
- Understand relational tables, SQL basics and common database objects.
- Prepare a PDF reader and a small disposable dataset for repeatable tests.
- Keep a table for concepts, examples, assumptions, mistakes and review dates.
Quick start
- 01
Draw the data model
Record row grain, keys, relationships and constraints before discussing normalization or indexing.
- 02
Practise SQL and transactions
Run a few queries, mark transaction boundaries and compare isolation behavior, rollback results and error conditions.
- 03
Compare performance choices
Relate an index or query rewrite to its expected access path, then retain the plan, data scale and database version.
- 04
Map backup to recovery
Put backup type, recovery point, recovery time, validation and rollback path in one comparison table.
Usage tips
- Keep the business grain beside every schema decision so technical terms remain tied to a data question.
- Record product, version, charset and transaction settings when comparing SQL results.
- Treat recovery objectives and restore verification as first-class concepts, not as command memorization.
Troubleshooting and uninstall
Why does SQL behave differently on another database?
Compare product, version, data types, functions, collation, transaction settings and execution plans before judging the result.
How can I tell whether backup knowledge is complete?
Explain the recovery point, recovery time, validation method and failure rollback path in addition to naming the backup type.
Frequently asked questions
Which database topics are included?
The Chinese PDF covers data modeling, design, SQL, transactions, indexes, backup, recovery and operations review.
Can SQL examples be copied across database products?
Basic syntax overlaps, but functions, types, isolation and execution plans vary; keep the product and version with each exercise.
What format and size is the file?
The indexed resource is a 104.18 KB PDF; verify the filename and size after downloading.
