Lossless Compression
Huffman-Encoding: Performing a frequency table.
-RLE (Run Length Encode): Replaces sets of repeated values for a key with a numeric indicator (3 * 2).
-LZW (Lempel-Ziv-Welch): When you find a similar sequence to another, it is replaced by a code of two values, corresponding to how many steps are reversed and how much data is repeated (101 # 32). It is used in GIF or TIFF.
Lossy Compression
.- Method fractal: Divided into blocks, scaling, rotation, we can

9: Input Domain Partitioning & Boundary Test Cases
Domain Testing
Generate test cases by assigning specific values to input variables based on analysis of the input domain.
- Input Space: x1,…,xn represents an input space where each input corresponds to a single data item. Together, they form the input vector. When the vector takes on a specific value, it is called a test point or test case.
- Input Domain: All points that are allowable input combinations.
- Sub Domain: Subset
Java Programming: Controllers, Servlets, JSPs, and Data Streams
Types of Controllers
There are four different driver bridges or JDBC drivers defined by the JDBC specification from Sun.
Bridge 1
Drivers using the system as a gateway or bridge. One example is the JDBC-ODBC. This is not the best solution because in many cases it is necessary to install specific software on the client, besides being slow to access the database.
Bridge 2
This type of controller is called native API. The driver contains Java code in which calls are made to the native methods of the database
