Answer 1

The Analysis Phase is where the project lifecycle begins. The Analysis Phase is where you break down the deliverables in the high-level Project Charter into the more detailed business requirements. The Analysis Phase is also the part of the project where you identify the overall direction that the project will take through the creation of the project strategy documents.

Gathering requirements is the main attraction of the Analysis Phase. The process of gathering requirements is usually more than simply asking the users what they need and writing their answers down. Depending on the complexity of the application, the process for gathering requirements has a clearly defined process of its own. This process consists of a group of repeatable processes that utilize certain techniques to capture, document, communicate, and manage requirements. This formal process, which will be developed in more detail, consists of four basic steps.

1. Elicitation – I ask questions, you talk, I listen

2. Validation – I analyze, I ask follow-up questions

3. Specification – I document, I ask follow-up questions

4. Verification – We all agree

Requirements modeling is one of the earlier phases of software development where requirements are captured and analyzed. This is a critical phase as it is important that requirements are not in conflict with each other and to check that they are complete. Finding these types of issues later in the development process can be time and resource intensive. Requirements can be authored in a textual format and then modeled at a high level using modeling tools. Test cases derived from this early phase of design can be re-used during the later implementation phases.

In simple terms, data modelling is nothing but a process through which data is stored structurally in a format in a database. Data modelling is important because it enables organizations to make data-driven decisions and meet varied business goals.

The entire process of data modelling is not as easy as it seems, though. You are required to have a deeper understanding of the structure of an organization and then propose a solution that aligns with its end-goals and suffices it in achieving the desired objectives.

Five Types of the Data Model:

1. Hierarchical Model:
   The hierarchical model is the first DBMS model; it represents the data in a hierarchical tree structure. The data is sorted hierarchically, and the arrows are used to navigate through the stored data.
   
2. Relational Model:
   The relational model represents the data in tables, and it is based on first-order predicate logic.
   
3. Network Database Model:
   Network Database Model is similar to the Hierarchical Model. However, the Network database allows a record to have more than one parent while Hierarchical Model does not allow more than one parent.
   
   Network Database does not require the parent to child relation, unlike the hierarchical model. It represents the data as a graph and the record type and allows one to many relationships.
   
4. Entity-Relationship Model:
   Entity-Relationship Model is useful in developing a conceptual design for the database. This model is easy to design with an ER model constructed.
   
5. Object Model:
   Object model uses the objects, classes, and inheritance to store the data. The object model is used for complex applications as well as in the file management system.

What is break-even analysis?

A break-even analysis is a useful tool for determining at what point your company, or a new product or service, will be profitable. Put another way, it’s a financial calculation used to determine the number of products or services you need to sell to at least cover your costs. When you’ve broken even, you are neither losing money nor making money, but all your costs have been covered.

For example, a break-even analysis could help you determine how many cell phone cases you need to sell to cover your warehousing costs. Or how many hours of service you need to sell to pay for your office space. Anything you sell beyond your break-even point will add profit.

There are a few definitions you need to know in order to understand break-even analysis.

• Fixed Costs: Expenses that stay the same no matter how much you sell.
• Variable Costs: Expenses that fluctuate up and down with sales.

The final stage of the analysis phase is to organize this information into documents that will guide the work during the rest of the project.

The three important deliverables created during this phase are:

• The business requirements report.
• The conceptual systems design plan.
• The strategy documents.
