In summary, there are three points to remember with respect to DBMS support for concurrency control and recovery: 1 Every object that is read or written by a transaction is rst locked in shared or exclusive mode, respectively Placing a lock on an object restricts its availability to other transactions and thereby a ects performance 2 For e cient log maintenance, the DBMS must be able to selectively force a collection of pages in main memory to disk Operating system support for this operation is not always satisfactory 3 Periodic checkpointing can reduce the time needed to recover from a crash Of course, this must be balanced against the fact that checkpointing too often slows down normal execution visual basic fill pdf VB .

One solution to Exercise 14-1 (continued) The PL/1 function SUBSTR(string, begin [,length]), used extensively in this model program, takes a number of characters, up to the value length, out of astring of characters, beginning at position begin Console.WriteLine(a); Cat c = a as Cat; // cast to cat if (c != null) // if it is a cat { c.Purr( ); // only cats purr } } } static void Main( ) { Tester t = new Tester( ); t.Run( ); } } } A system such as RETRIEVE is not adequate to support a general database No means exist to cross-reference multiple les, and the data elements are limited to two simple types The fact that the les are strictly sequential can cause long delays on large les On the other hand, the facilities are easy to comprehend by the types of users the system designers envisaged, the possibilities for processing errors are reduced, and results of processing are well identi ed The facilities shown here are similar to those for manipulating a single le or relation of a larger system Solution to Exercise 14-2. Replace the array in Exercise 14-1 with a List. Sort the animals by size. You can simplify by just calling ToString( ) before and after the sort. Remember that you ll need to implement IComparable. The first thing you need to do here is replace the array in Run( ) with a List, specifically a List<Animal>. You don t need to worry about the size of the List; you can just call Add( ) to add each element to the List. Output the values of the list (using a foreach) once, then call Sort( ) on the List, and output the values again. For the Sort( ) to work, you ll need to make sure Animal implements IComparable. To sort on the animal s weight, you ll need a CompareTo( ) method that delegates responsibility for the comparison to the int version of CompareTo( ), using Animal.weight. Example A-39 shows one way. Figure 13 shows the structure (with some simpli cation) of a typical DBMS based on the relational data model Sec 8-2 Example A-39.
