Data Partitioning and Relational Model Implementation
Implementation of Data Partitioning through Range
Step 1: Create a Database
mysql>create database mca;
mysql>use mca
Step 2: Create a Partitioned Table
mysql> CREATE TABLE tr (id INT, name VARCHAR(50), purchased DATE)
PARTITION BY RANGE (YEAR(purchased)) (
PARTITION p0 VALUES LESS THAN (1990),
PARTITION p1 VALUES LESS THAN (1995),
PARTITION p2 VALUES LESS THAN (2000),
PARTITION p3 VALUES LESS THAN (2005),
PARTITION p4 VALUES LESS THAN (2010),
PARTITION p5 VALUES LESS THAN (2015)
);
Step 3: Insert Data

Understanding Mobile Network Architectures: From GSM to 5G
LTE Network Architecture
The Long-Term Evolution (LTE) network architecture consists of three main components:
- User Equipment (UE): Devices like smartphones or tablets that connect to the LTE network.
- Evolved UMTS Terrestrial Radio Access Network (E-UTRAN): The radio access network with eNodeB base stations, providing the connection between the UE and the core network.
- Evolved Packet Core (EPC): The core network handling signaling and data traffic, including nodes like the Mobility Management Entity
Software Engineering and Project Management Overview
Features:
Software does not wear, is not sensitive to environmental problems, failure means whole design or implementation error: SW maintenance is more complicated than the HW, Most software is tailored. Today: Object Orientation, Reusability ( reduces costs and improves designs).
A computer system is characterized by d: Hardware – Software-Information – Users – Tasks – Documentation
Software applications: Basic Software – Real Time – Shopping – Science or Engineering – Embedded – Personal Computer

Basic Concepts
Various Wireless Spectrums: range, data rate, frequency, technologies
Wireless technologies: WHAN, WPAN, WLAN, WMAN, WWAN
Cellular Networks: 0g, 1g, 2g, 3g, 4g
Bandwidth
– Data rate, frequency, channel width
• Throughput
– Bandwidth, data rate, output, good‐put, as well as link, path, system throughput
Throughput is achievable data rate
Capacity is the maximum throughput
Wireless is primarily in Layers 1 and 1⁄2
All Wireless Networks are in Cellular format, 8/29/2017
