Network Database Models,anguage. During the late 1960s, CODASYL extended its area of interest to include all areas where COBOL might be used. The possibility of COBOL accessing a database led to the formation of a group within CODASYL to define a CODASYL database model. The resulting model, which has been updated at interv作者: ABIDE 時(shí)間: 2025-3-22 16:12
Relational Database Models,gical model which is further removed from the physical implementation than was the case for the network models examined in the previous chapter.

Network Database Models,als, has been implemented by many computer manufacturers and software houses. The CODASYL database is known as a network database model. In this chapter we will examine the major components of this model and see how our conceptual models have to be altered to form CODASYL logical models.作者: URN 時(shí)間: 2025-3-24 01:54

Dynamic Data Structures,deleted from the middle of the list, all following items must be moved up to fill the gap. Secondly, if the items are held in a specified order, the addition of a new item to the middle of the list also requires other items to be moved. The third problem is that the size of the array limits the size of the list.作者: 老人病學(xué) 時(shí)間: 2025-3-25 03:34
Non-serial File Access,cts of file design covered in this chapter are only supported by extensions to the Pascal language.

Database Design,s first stage is called . A conceptual model serves two main purposes.

Lecture Notes in Computer ScienceThe name ‘fourth generation language’ or 4GL has become widely used in recent times, yet there is no precise definition of it. The difficulty is in saying exactly what features are expected in a 4GL, even though the notion of ‘fourth generation’ is easy to explain.作者: adhesive 時(shí)間: 2025-3-28 21:47
