Candidate: Experience in database design. The successful candidate will be given access to an inventory management software to analyse and from there create the following: 1st - Database design is connected with application design. The requirements and the collection analysis phase produce both data requirements and functional requirements. The data requirements are used as a source of database design. The data requirements should be specified in as detailed and complete form as possible. 2nd - Conceptual Design Once all the requirements have been collected and analyzed, the next step is to create a conceptual shema for the database, using a high level conceptual data model. This phase is called conceptual design. The result of this phase is an Entity-Relationship (ER) diagram or UML class diagram. It is a high-level data model of the specific application area. It describes how different entities (objects, items) are related to each other 3rd - Logical Design The result of the logical design phase (or data model mapping phase) is a set of relation shcemas. The ER diagram or class diagram is the basis for these relation schemas. 4th - Normalization Normalization is the last part of the logical design. The goal of normalization is to eliminate redundancy and potential update anomalies. Redundancy means that the same data is saved more than once in a database. Update anomaly is a consequence of redundancy. If a piece of data is saved in more than one place, the same data must be updated in more than one place. Designs Conceptual, Logical and Physical data models for scalability/flexibility/Extensibility. Performs Data analysis/Profiling to evaluate data and underlying data structures. Documents and publishes the data dictionaries/Metadata, data models to ensure their correct implementation Competencies: Communication Proficiency. Technical Capacity. Time Management.

This project is to set up a database on AWS to support a mobile app. The database should be a classic rational database (i.e. not no SQL). Part of the task is to suggest what database to use. The database will contain content used in the app, including translations for all text used in the app. The system will be localized to many different languages. At first to English, Simplified Chinese and Traditional Chinese, but over time to other languages, including Arabic. The app will have a database, where the AWS one is the master. Part of the task is to work with the app developer to figure out how best to synchronize the databases. The client database will gather some user data that should be copied back to the AWS one. The first client is an Android app on a customized IOT device. Later we will add mobile apps on Android and iOS, and then a web site, that uses the data as well. We will be using Json here. The first market is China, though we will initially be hosting on AWS Singapore (probably) and later on AWS Beijing. A follow up project to this is to develop a web form to update the database. The markup will be provided, but if you are good at this, then you can offer to do that as well. The database is small to begin with, including only a few thousand rows of code. We will have around 15-20 tables.

Build a survey linked to a database. The survey will match real estate seekers with local communities, matching the seeker's requirements to the community's characteristics. The seeker will enter answers such as "How close to the beach do you want to live?"or Do you want a community that allows pets? There may be 4 or 5 possible answers. A,b,c,d,e. Yes/No For step 1, there will be 3 qualifying questions. Initially there will be 50 - 100 communities. (possible answers) However, it must be expandable to 100s of thousands community possibilities. At the end of the 1st step of the survey, they will be given a list of the top 3 local communities that match their requirements. The results will be ranked in order of closest match. If there are more than 3 that match, the survey results need to be randomized. The results will include one unique link for each result that will give the user the opportunity to learn more about that community. There is also a link to get more detailed results by providing their first name, last name, phone # and email address. Step 2. User opts in to provide their first name, last name, phone # and email address. These fields are all required to move to the next step. (the data collected here needs to be able to be changed, so if we want to collect different data at some point in the future we can.) The answers provided in step 1 needs to be collected and associated with the first name, last name, phone # and email address; so we can go back and look at the answers to the first series of questions and associate those with the user. Step 3. the user has provided first name, last name, phone # and email address. The next step will take them to a more in-depth survey of about 12 questions, which again would provide the top return results with a link to each individual landing page. The answers to the survey questions at this point needs to be attached to the users data record from the first series of questions and user's information. The database needs to capture all of the data that is input including answers to the questions and email, if the first name, last name, phone # and email address fields are populated. The number of survey questions needs to be expandable to at least 25. (This would be potentially used down the road.) The interface needs to be simple - like WordPress where someone can log in and change the questions for the survey if they want, see the results from the survey takers and add new community information that would drive the survey responses. In the future, we want to be able to create an embed code for this survey to be used on multiple websites. Create a unique product key unique to each for the embed code, so that the code will expire after a set period of time or can be renewed based on qualifying for renewal. Embed code must be universal for all types of website platforms. I've attached a screen shot to give you an idea of what we are referring to.
