4. Data structure
Data structure refers to the data objects and their relationships and construction methods. In the software design process, the choice of different data structures, impact on the final performance of the system greatly. So the knowledge is the core software designers test center, whether it is general knowledge part of the morning, afternoon or software design, test scores are high.
According to syllabus, this chapter require candidates to master arrays, linked lists, stacks and queues, trees, graphs, hash knowledge, from the calendar year exam situation, this chapter examines the content stored in the logical structure and characteristics of common data structures.
Basic knowledge of database systems
From the calendar year exam situation, test centers this chapter focused on: ER model, relational algebra, tuple calculus, normalization theory (key, paradigm, mode decomposition), SQL language.
