A unique username and password must be configured during the JUNOScope software installation to enable read-only access to the Inventory Management System database. Figure 7: Export Inventory Management System Data Topology Diagram Browser Client HTTP or HTTPS JUNOScope Server JUNOScript Router 0 JDBC SQL MySQL (bundled) Router 1 Router 2 External Inventory Apps localhost g External inventory applications can extract inventory data, such as hardware, software, licensed features, and inventory scan events, from the JUNOScope Inventory Management System database. (See Figure 7.) The query examples used in this chapter to extract inventory data are for MySQL. The JUNOScope software is bundled with MySQL, an open source relational database management system (RDBMS). This chapter describes how an external inventory application can connect to the JUNOScope Inventory Management System database and extract Juniper Networks device inventory information by way of an SQL interface. Refer to your applicable SQL guides for complete reference information. It is not meant to be a complete SQL reference.

In practice, I use it with Laravel, and I use a console command, which will compute my product stock in batch (I also use an optional parameter to compute only for a certain product id), so my stock is always correct (relative to the query above), and I never manually update the stock table.1 Chapter 30 Exporting Inventory Management System Data This chapter is intended for users who are familiar with Relational Database Management Systems (RDBMS) and the Structured Query Language (SQL), who want to develop their own customer applications to access information from the JUNOScope Inventory Management System. This is for reliability reasons: to freeze the price at the moment of the purchase, and to be able to recompute the total with a lot of decimals (without loosing cents in the way). You see in the product_order, I duplicated the price and the vat. But that is another deal.Īnyway even if the stock recomputation query is using anonymous subqueries, it should actually be quite fast enough in most of the relatively medium stores. You could imagine creating another table that stores the fact that a stock is being recomputed, and make the user wait until the recomputation is finished (push request or long polling) in order to check if every of his/her items are still available (stock >= user demand). I think another downside could be if you are managing high traffic store. You will deliver faster responses through your API. One of the downside is the data duplication, because you will need to rerun the query above to update your stock (see the updatedAt column). While this could save you one table, you will not be able to scale with it, hence the fact that most of the modelization (imho) use an intermediate stock table, mostly for performance concerns. Which would give something like: id name stock If we stop to this, we could compute our actual stock which would be transcribed into this SQL query: SELECT Supplying act as my +stock, and my orders my -stock. In order to modelize stock movement (+/-), I have my supplying and my order tables. I have the same need, and here is how I tackled your stock movement issue (which became my issue too).

The Type_Movement is either In / Out.īut I'm a bit lost here, I really don't know how to do it nicely. That's why I thought about a Movement_stock table. I wanted to create a design where I'd be able to see when a specific Item is pulled out of our stock, and when it enters the stock with the date. The main concern here is the link between Stock, Item, Movement stock. But here, I have a problem, shouldn't the order table be related to Product ? Products are related to a specific supplier, to whom we can take orders. I thought about doing this, because I'll need to have a trace of where a specific item is, if it's at a client house (rented), if it's sold, etc.

So we have an Product table (which is the type of product : alarms, alarm watches, etc.), and an Item table, which is the item itself, with it unique serial number. We sell and rent alarm systems, and we want to have a good overview of what product is still in our offices, what has been rented or sold, at what time, etc.Īt the moment I thought about this database design :Įverytime we create a new contract, this contract is about a location or a sale of an item. I'm creating an Intranet for my company, and we want to have a stock management in it.
