Description
Experience Level: Expert
This is a writing project.
don't need a perfect grammar, nor copy paste from the web.
I need an expert to explain the concept and give specific examples, preferably with CRM server and clients.
with examples with java database, gRPC, H2, MQSQL, JPA, JOOQ, JDBC. just a mention is enough.
how the process of requesting to retrieve a data is sent, how API does this, where is data abstraction layer, where is data access layer, how it find the data by hash function or lookup tables.
NOT TOO MUCH DETAIL, JUST EXPLANATION OF WHAT IS HAPPENING.
How library allows users to access, retrieve a data in tables of key, value pairs, sorted sets, maps, fat events.
Examples of each data structure where they might be used, for example in key value pair table, user may store first name, last name or in iWatch, each user's heart rate can be a value where each user's apple ID is the key. and because it's small database, it's written in H2 and embedded on iWatch not server.
Or fat events table may have a timestamp column to store data associated with a time.
I need a detailed paper or essay about
1- data abstraction layer, it's purpose, it's function, it's location, how it's implemented.
2- how it's used in embedded database, for small apps where all data are stored in mobile device, give case study with specific examples with key, value pairs, sorted sets, maps, fat events, preferably with CRM server and clients
3- how it's used in client server model, where the database in on server, for example in distributed network servers, for large projects, , give case study with specific examples with key, value pairs, sorted sets, maps, fat events, preferably with CRM server and clients
4- how tables are generated, give specific examples for tables of key, value pairs, sorted sets, maps, fat events, preferably with CRM server and clients
5- explain hash function, and how it's used in finding a table in database,
6- explain how data abstraction layer is used, where and how the latency and dependencies occur.
7. difference between data access layer and data abstraction layer
I might have some questions if the paper is not complete or clear.
tell me when you can deliver and your experience with this topic, and some examples of your past works.
I need this by today 2/12/2019 or at most by tomorrow.
thanks
