An analytical tool is something used to analyze or "take a closer look at" something. It is normally a way to review the effectiveness of something.
For example, Google offers a free web analytics tool that is used by Web Masters to track visitors on a given site. It allows Web Masters to see where visitors are coming from, how long they stay, what links they are reviewing, etc.

Data flow diagram
-A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system, modeling its process aspects. Often they are a preliminary step used to create an overview of the system which can later be elaborated.[2]DFDs can also be used for the visualization of data processing (structured design).

HIPO
-The HIPO (Hierarchy plus Input-Process-Output) technique is a tool for planning and/or documenting a computer program. A HIPO model consists of a hierarchy chart that graphically represents the program’s control structure and a set of IPO (Input-Process-Output) charts that describe the inputs to, the outputs from, and the functions (or processes) performed by each module on the hierarchy chart.
Using the HIPO technique, designers can evaluate and refine a program’s design, and correct flaws prior to implementation. Given the graphic nature of HIPO, users and managers can easily follow a program’s structure. The hierarchy chart serves as a useful planning and visualization document for managing the program development process. The IPO charts define for the programmer each module’s inputs, outputs, and algorithms.
The HIPO technique is often used to plan or document a structured program (# 62). A variety of tools, including pseudocode (# 59) and structured English (# 60), can be used to describe processes on an IPO chart. System flowcharting symbols (# 37) are sometimes used to identify physical input, output, and storage devices on an IPO chart.
