... I had no desire to create adatabase and store images in it. More importantly, I had no desire to figure out what image types(JPEG, BMP, PNG, etc.) were actually supported. I know why pictures were added, but I neverplayed much in that world. Images were added so store catalog/inventory records could contain amemo field with the item description, and a picture field with an image of the item. If you havean eBay store with around 100 items, this is fine. If you are running a serious business or think itmight turn into a serious business, you should really start with a relational database and bolt onwhat you need later. (Remember that 2GB data file limit? We always say the 4GB file limit wasimposed by FAT32, but have you checked the header file and 10 digit tag algorithm of a memofile to ensure it isn't limited by an unsigned 32bit integer as well?)1.101.101.101.101.101.10 Programming Assignment 3Programming Assignment 3Programming Assignment 3Programming Assignment 3Programming Assignment 3Programming Assignment 3Modify the last two dump_records() calls in testShowMe.java to dump only the second recordof class.dbf and only the third record respectively. This is a very simple assignment designed tobuild confidence in the boundary logic of the dump_records() method.Create your own version of testShowMe.java which operates on the teacher.dbf file. I haven'tprovided you the source to create the teacher.dbf file, so you will need to pull it down from thexBaseJ project site.63Chapter 1 Fundamentals1.111.111.111.111.111.11 Descending Indexes and Index LifespanDescending Indexes and Index LifespanDescending Indexes and Index LifespanDescending Indexes and Index LifespanDescending Indexes and Index LifespanDescending Indexes and Index LifespanYou have already seen how indexes can be useful when it comes to keeping data in a sortedorder. Even if the data isn't physically sorted, the index allows you to retrieve it in the order youwant. ... value until a newer record is added. This method looks much like our otherfind methods. We establish a key of reference, call startTop() to establish a position, then callfindNext() to pull in the record.You might think at first glance that get_next() is coded incorrectly. It makes no attempt toestablish any key of reference or position via that key. It couldn't care less where it is or where itis going. If you happen to hit one end or the other on the file it will let you know by returningDOE_KEY_NOT_FOUND, otherwise it returns DOE_SUCCESS and you can be fairly certainyou got the record you wanted.If you were confused by get_next() or get_newest(), then you should love get_oldest(). It'snot a complex routine; it simply needs you to really understand both how the indexes work and what the key actually contains. Remember, indexes are stored only in ascending order with thislibrary. The smallest date value on file will be the first record in the primary index. We find theoldest record by getting the record at the top of the primary index (K0) and the newest record bygetting the record at the top of the secondary (K1) index. It is true that you could also get thenewest record on file by calling startBottom() on the primary key and work your way back to theoldest record ... method must physically free any resources (other than dynamically allocated RAM)which might be needed somewhere else.
